Be sure to visit us for our upcoming Garage Sale August 30-31, 2019 and scoop up some amazing bargains by the pound. We are overrun with donated material from local rockhounds, and we are running out of storage space. This material is priced to sell! The rough lapidary material and yard rocks are at especially attractive prices.
We’re hoping to declutter the storage area and reduce the inventory we’ve accumulated not just this summer, but over the years. At a similar event for Memorial Day earlier this year, many of you suggested we should do another one – so here it is!
This time we’ve got some interesting material we picked up from multiple sources. First and foremost, we’ve got excess zeolites from the late Rudy Tschernich, our former curator and author of “Zeolites of the World.” The museum hosts some of the finest zeolite specimens anywhere on display in the Northwest Gallery, but if you knew Rudy, you can imagine we have tons more from some of the best zeolite localities known, including Robertson Pit in Washington, the Goble area in northwest Oregon, countless basalt quarries in western Oregon, and even a few from India and Europe.
Rudy’s definitive book is available for free download as a PDF. By the time he retired, Rudy donated over 13,000 zeolites to the museum, and we probably have the finest collection anywhere. There are countless duplicates, however, so we’ve made about 100 available for sale this year.
Zeolites from Succor Creek and Rickreall, from the collection of Rudy Tschernich.
In addition, super-volunteer Linda Harvey journeyed north to tackle famed mineral collector Bob Jackson’s storage area, where she picked up pounds of Spruce Ridge material. Bob’s claim up near Snoqualmie Pass in Washington has yielded amazing clusters of nicely terminated quartz crystals, with large pyrite crystals interspersed.
Some of the clusters offered for sale will need to be cleaned; museum staff manning the garage sale can provide you with tips on the right kitchen chemicals to use.
On top of all that, we have taken in a few hundred pounds of material collected from the Nehalem River. This material includes a fine red jasper and some interesting agate.
Some drop by, bring a bucket, and go home with some interesting pieces. You’ll be supporting the museum and snagging some great collectibles.
If you collected some strange rocks over the summer, bring them in Saturday, August 24 from 10:00 to 2:00 to see if you can stump the experts. We’ll have several geologists, mineralogists, and rockhounds available to identify your finds. Or, if you’ve been wondering what the heck that strange rock is that you think might be a meteorite, now’s the time to get it checked.
Remember, all you need is a paid admission to the museum to participate. While you’re here, be sure to check the Spann Exhibit, the Snook Exhibit, and the “Brilliance of Trilliants” exhibit – all three went up since the first Mystery Mineral Day of the year back in February.
Vendors are already hard at work preparing for the opening of SummerFest 2019 on Saturday morning, August 3. The event runs both Saturday and Sunday from 10-5, but many of the vendors get their setups going as early as possible, to get their booths and tables squared away.
If you’ve never been to our SummerFest celebration, you owe it to yourself and your family to drop on by. We’ll have more vendors this year, expanded activities for kids, and upgraded food options. And parking is easier, too! Learn to pan for gold, shop for fantastic rocks and minerals, explore the many jewelry options, pick up information from the strong local clubs that specialize in rocks, gems, prospecting, and faceting, and have a great time.
One of the most popular attractions at our museum is the Rockpile, a regularly-stocked 10×10 area containing agate, jasper, petrified wood, quartz crystals, sunstones, and other collectibles. We try to maintain a regional flavor to the material, but that’s not always easy. Plus, there’s good stuff from other locations that the kids enjoy. So we recently made a trip to Oregon Decorative Rock in Beaverton to see if they might help us spice things up. They have the largest selection of natural stone in the Pacific Northwest, and if you haven’t been there, you should make the trip.
Over the years, the Rockpile has expanded and contracted in size. At one time, it was a couple feet high. Last year, a local group of Scouts set up a project to screen out the dirt and rehab the mound.
The collectable material is hidden among more common rocks, making it a treasure hunt at times. Kids get one free rock from the Rockpile as part of their admission, and senior citizens who can no longer mount their own expeditions to collect in the field still get a little surge of excitement picking through the pile. With so many people touring the museum, it takes a lot of material to keep things interesting.
Rockpile Manager John Lillie said journeying to Oregon Decorative Rock was a real treat. The abundance was almost overwhelming, he reported. “I was really happy to see the wide variety of material on hand,” John said. “I realized immediately that they had kid-sized rocks that would make the students really happy.”
Oregon Decorative Rock manager Jim Reed was a huge help, and gave the museum a nice discount. Reed said he’s a big fan of the museum, and he hears about it from customers all the time. “I’ve have hundreds of customers mention you guys,” he told John. “We’re happy to help,” he added.
John returned to the museum with interesting new material. Some of the new additions to the Rockpile include polished black quartzite from Mexico, polished white and yellow quartz from the Southwest, and a striking blue-green aventurine from Montana that is still rough. The new black, white, and green mix makes a nice contrast to the current material, and response has been positive.
John has completely overhauled the Rockpile storage, inventory, and accounting process, and he is making a huge difference. He is semi-retired and energetic, and is a former project geologist who specialized in environmental remediation in his career. He now stays busy part-time at the museum as a host and serves as an interim museum store manager. The Rockpile is his favorite job. “Occasionally we get material from local rockhounds that goes right to the pile,” he said. “It’s fun to talk with them, and I try to get enough information about what they’re bringing in that I can tell the students what they’re looking at.”
“The aventurine has already been a big hit,” John continued. “The kids can spot it from a long way off, and it just seems to call to them.” If you’re not familiar with aventurine, that’s understandable. There is only one good occurence of aventurine in the Pacific Northwest, located on public land near Omak, Washington. The green aventurine sold by Oregon Decorative Rock is found in the gravel beds of the Yellowstone River, and is called Glacier Green. It is actually a form of quartzite, containing interlocking grains of quartz and other minerals. Small flecks of mica are sometimes contained in the stone. It can also come in red, but the characteristic green-blue is extremely popular.
The museum welcomes donated material from local rock clubs and rockhounds to keep the Rockpile interesting, but please don’t dump material directly to the pile. We’ve had problems in the past with obsidian shards and sharp jasper pieces that we didn’t know were in there until it was almost too late. It’s very important that you check with a museum employee when you donate rocks – you get a form for your taxes, and we can track the donation.
Note also that we are not set up to purchase collections. Families contact us regularly asking if we can buy their rocks and gems, ranging from unidentified specimens to yard rocks. We rarely see anything that we need, so we suggest visiting Treasures in the Grove, the nearest rock & gem shop in Forest Grove.
Stocking the Rockpile with Pacific Northwest material will always be an important part of what Richard and Helen Rice envisioned when they got things started here. Still, it’s fun to experiment with material from a supportive local business and spice things up. We’ll be going back to Oregon Decorative Rock soon, to see about landscaping material for our paths and gardens. They’ve been “All About Rocks” since 1976, and we speak the same language!
If you’ve always had a fascination for volcanoes and earthquakes, Rice Northwest Museum of Rocks and Minerals shares your passion. On Saturday, May 11, 2019, we’ve scheduled a full day of events with demonstrations, family activities, and talks by volcanologists from the U.S. Geological Survey Cascades Volcano Observatory.
We live in a highly volcanic region – most of us in western Oregon can see one or two volcanoes when the weather is right. But what do we really know about these icons? Volcano Day is a good opportunity to learn more about our local geology.
Talks and demonstrations will take place throughout the day. We encourage you to try to time your visit for talk and demonstration.
Event Schedule: 10:30 – 11:00 – Talk by USGS Scientists Liz Westby and Carolyn Driedger 11:00 – 12:00 – Trash-Cano eruption & other demonstrations 12:00 – 12:30 – Talk by USGS Scientists Liz Westby and Carolyn Driedger 12:30 – 01:30 – Trash-Cano eruption & other demonstrations 1:30 – 2:00 – Talk by USGS Scientists Liz Westby and Carolyn Driedger 2:00 – 3:00 – Trash-Cano eruption & other demonstrations 3:00 – 3:30 – Talk by USGS Scientists Liz Westby and Carolyn Driedger 3:30 – 4:00 – Trash-Cano eruption
This event is included with regular museum admission. Admission costs $12.00 for adults, $10 for seniors over 60, $8 for kids ages 5-17, $8 for veterans and active military. Admission is free to members and children 4 and under.
The most popular demonstration by far is the famed trash-cano – a simulation of a volcanic eruption done by blowing up a trash can using liquid nitrogen.
Other hands-on demonstrations will be available, including Lahar-in-a-Jar, a demonstration of pyroclastic mudflow.
In addition, we’ll be honoring the 39th anniversary of the May 18, 1980 eruption of Mt. St. Helens. Local collector Mike Medvec will bring his collection of Mt. St. Helens memorabilia and will be available to discuss the eruption throughout the event.
For those of you who don’t remember the rumbling blast of power that echoed across Portland and down the Willamette Valley, it was a signature event in our history. Many still remember being a long ways away that Sunday morning and hearing a thunderous sound around 8:30 am.
Unfortunately, 57 people died in the 1980 eruption, including USGS volcanologist David A. Johnston, for whom the USGS Johnston Ridge Observatory is named.
Subsequent eruptions dumped volcanic ash locally on rooftops as far as Forest Grove. Heavier ash accumulations reached eastern Washington, Idaho, and even Oklahoma. It was a mess. But it was scientifically fascinating.
Geologists had warned for years that our volcanic neighbors were not extinct, just quiet. Native American legends recalled Mt. Hood (Wyeast) and Mt. Adams (Klickitat) “fighting” over the beautiful maiden Loowit. The mountains hurled rocks at each other, started fires, and shook the earth, according to the stories. Angered, Tyhee Sahale turned all of them into mountains, with Loowit transformed into the once beautiful symmetrical cone-shaped volcano we know as Mt. St. Helens.

In the fossil conservation world, the concept is the same, but the mechanics of making it happen are a bit more complex. For one thing, it can take four strong backs and a truck just to leave home. But thanks to a collaboration with the Oregon Museum of Science and Industry (OMSI) and the North America Research Group (NARG), the Rice Northwest Museum of Rocks and Minerals recently shipped a 100-lb. fossil skull to OMSI to be prepped for eventual display here.
First, some background. Many years ago, the museum took possession of a 34-million-year-old mammal skull from the famed Chadron Formation of South Dakota. Known at the time as a titanothere, the animal was part of a now extinct group of gigantic rhinoceros-like perissodactyls (odd-toed ungulates, or “hoofed mammals”). These behemoths roamed in herds, primarily in the Badlands area of the United States and Canada. Now usually dubbed “brontotheres,” (thunder beasts) these enormous animals were the largest North American mammals during the Eocene, standing up to 8 feet tall at the shoulder, and reaching 14 feet in length. They were so abundant during their time that entire fossil beds have been found at several locations in the Badlands area.
Brontotheres were browsing herbivores with large “W” shaped molars, useful for grinding and chewing. They had a large bony “Y” shaped horn, which protruded just above the nose. The horn was much larger on males and probably used for head butting. The head was large, but the eyes were small and located on the front of the head. Ears were situated at the back. The body resembled a rhino, but the legs and feet were more like an elephant.
As brontotheres evolved, the core of their horns grew larger and longer. They had fewer incisors, which might have been related to development of a prehensile (able to grasp) lip. Their nasal canals shortened.
Most brontothere fossils are recovered from North America, although some have been found in Asia.
Connected to Famous Bone Wars
Dr. Hiram Prout, a St. Louis physician, described what was dubbed a titanothere jaw in 1846. It was the first scientifically described fossil specimen from the American West and discovered in what is now Badlands National Park. The jaw is now in the collection of the Smithsonian Institution National Museum of Nature.
The famous fossil hunters O.C. Marsh and Edward Drinker Cope gave the varied fossil titanothere-related specimens many different names, based on the shape of the horns. It turned out the horns were highly variable within a single species, and if Cope and Marsh weren’t so competitive about discovering and naming new fossils, in what became known as The Bone Wars, they might have figured the horn variability out on their own. After later paleontologists studied large collections of skulls occurring together from the same areas, they discovered that one shape actually grades into another.
Over time, more researchers adopted the brontothere name, but the scientific literature still retains numerous references to titanotheres, so both names are used. The key source for North American brontothere fossil remains is the Chadron Formation. According to the literature at the website of Badlands National Park, the Chadron is found in North Dakota, South Dakota, northwestern Nebraska, and eastern Wyoming. It is named after the town of Chadron, Nebraska and was mapped out by Carl Vondra in the 1950s. The greyish Chadron Formation was deposited between 34 and 37 million years ago by rivers across a flood plain. Each time the rivers flooded, they deposited a new layer on the plain. Alligator fossils indicate that a lush, subtropical forest covered the land. Most fossils found in this formation are from early mammals like the three-toed horse and the large titanothere.
Into Our Collection
This particular fossil skull came to the Rice Museum five years ago as a donation by a local dentist, who displayed the skull in his office. It was in bad shape, and the movers accidentally broke it during transport, adding further insult. A fossil preparation expert from NARG took over the skull and put in considerable time stabilizing the specimen. He also embedded a crucial metal strut under the hard palate because there was too much plaster to give any meaningful support.
The skull came back to the museum, but it still needed a lot of work before it could go on display, and volunteer help at NARG was then consumed with preparation of a recently discoveredthalattosaur, a sea-going reptile discovered near Mitchell, Oregon. The skull gathered dust until recently, when it made its trip to OMSI. But now that the specimen is back in the lab, it’s time for some serious pampering.
Local fossil preparation expert Greg Carr is spearheading the project. He determined that there are three layers of restoration to update, including a coat of white paint over drywall mud and lime mortar, plus several applications of PaleoBond glue. “I plan on cleaning off the drywall mud and smoothing out the lumpy Bondo with a Dremel,” he reported. He will remove some of the lime mortar to expose as much bone as possible, but not endanger the mechanical strength.
we’ll repaint the filled-in parts to complement the bone,” Greg said. “We’ll build
a mount to hold the skull about one foot above a strong plywood base, then add
lights and mirrors to highlight the wonderful teeth,” he added.
about one day a week, Greg estimates it could take a year to get the specimen
ready for a public display.
Sue Wu, OMSI Earth Sciences Coordinator, is enthusiastic about OMSI, NARG, and the Rice Museum teaming up. “I’m excited that we can partner with the Rice Museum on this project,” she said. “There are so many great science education organizations in this area. When OMSI can collaborate with places like the Rice Museum, we provide a richer experience for our visitors. Most visitors have never heard of this fossil mammal, so this is a rare opportunity for them to see a skull being worked on. I’m grateful to the Rice Museum for providing us with this opportunity.”
She said Greg is a good choice to lead the project. “He is the perfect person to be preparing the skull. Not only is he a highly experienced fossil preparator, he’s also a fabulous educator who loves showing and sharing with visitors what he’s doing with the fossil.”
Greg and his fellow volunteers already have a nickname assigned to the skull. “Another volunteer named Jack Pollock thinks we should nickname the beast ‘Lumpy,’” Greg said. “It seems very appropriate!”
Famed mineral photographer Jeff Scovil dropped by the museum recently to shoot pictures of some of our top specimens, as well as “glamor shots” for regional collectors. The Rice Northwest Museum of Rocks and Minerals is sponsoring six-pages featuring the best of the museum’s collection in a supplement to the The Mineralogical Record, to be published later this year. Many collectors in the area are participating in this project as well. Jeff recently set up a temporary studio at the Rice Museum to accommodate all the need for high-quality images for this project.
The title for the upcoming supplement is “Mineral Collectors of the Pacific Northwest.” The goal is to show off specimens from collectors in the northwest community and is open to public and private collections. Dr. Wendell E. Wilson, Publisher & Editor-in-Chief of The Mineralogical Record, said in a press release that the upcoming supplement will feature the best of collections of mineral enthusiasts living in Washington, Oregon, Idaho, Montana, Alaska, British Columbia, the Yukon Territory and Alberta.
The Mineralogical Record was founded in 1970 by John White, who was at that time a curator in the Mineral Sciences Department of the Smithsonian Institution. Today The Mineralogical Record continues to set the standard for quality content for the serious mineral collector. In 1982, The Mineralogical Record was honored with the naming of a new mineral species: minrecordite. In 1994, the publication won the prestigious Carnegie Mineralogical Award. It’s issues are collectibles in their own right, and are highly prized.
Based in Phoenix, Jeff has written numerous articles about his craft, and he published the definitive book on the subject: Photographing Minerals, Fossils, & Lapidary Minerals. His book shows amateur and professional photographers several techniques for getting the best possible images in both color and black & white. He explains the basic concepts, covers equipment and formats, and goes into detail about photographing transparent and opaque materials, with advice on lighting techniques, filters, photomicrography, stereo-photography, fluorescence, location photography, and slide presentations.
According to his website, when Jeff got his first camera from his father at high school graduation, it was the beginning of a lifelong passion. Jeff grew up in Connecticut and had been collecting minerals and fossils since he was eight years old. He started college majoring in geology, but switched to anthropology and archaeology. After one field season on a dig in New Mexico he became the site’s laboratory photographer. Jeff studied what little there was published on archaeological photography; finding the literature minimal, he started researching scientific photography from other fields and applied what he learned to archaeological materials.
After three years in the photo studio at the dig, he renewed his passion for minerals with camera in hand. Initial image results were disappointing but Jeff kept at it and started gaining recognition for his work. He photographing other collector’s articles for the popular magazines in the hobby such as The Mineralogical Record and Rocks and Minerals.
Jeff’s approach was summarized in an excellent Vimeo recording produced by Daniel Buckley for the Arizona Centennial’s virtual museum, arizonaexperience.org. “The most important thing…is that a mineral is a geometric solid…. I’ve developed a technique where I photograph on a piece of non-glare glass suspended above the background so that I don’t get reflections. I can light from behind, from underneath, and through the glass. Crystal faces are frequently extremely lustrous, so you’re trying to avoid burned-out highlights. Then I have another light, which is for the background. I usually have a third light, which I call a ‘kicker.’ The more you diffuse [the background light], you’re going to have fewer problems with reflections on faces. This little kicker adds sparkle back in and increases the color saturation and gives the specimen lots more life than you would get otherwise. Once you light the crystal, the actual definition of the crystal faces and the other attributes of the specimen is done with a variety of small cards that range in specularity from completely matte to highly reflective. So trying to balance the lighting can really be a task.”
Jake Slagle at Mineral Bliss sums up Jeff’s many credentials: “A recipient of the 2007 Carnegie Mineralogical Award, his work is everywhere in just about every issue of Rocks and Minerals, Mineralogical Record, and the mineral and lapidary magazines of France, Germany, Spain, Poland, and Russia, as well as in numerous books about minerals. The posters for most of the larger shows around the world (including eleven for the Tucson Gem and Mineral Show) bear his work, and he’s photographed the collections of scores of museums in the US and around the world.”
At Jeff’s website,
you can see multiple examples of his fine work. You’ll find extreme closeups of
malachite, agate, fluorite, and garnet, as well as stunning images of complete
minerals, fossils, meteorites, lapidary, archaeological artifacts, and more.

One of the best parts of working at the Rice Northwest Museum of Rocks and Minerals is the park-like setting on the grounds. We love our rocks and minerals, but we’ll talk at length about any of the earth sciences. For example, it’s common to see us commenting about deer on the lawn, elk in the fields, coyotes along the treeline, or raptors circling overhead. Lately, we realized we had to address some long-overdue management of our forested stands. We love our trees, but there are problems to fix.
One concern has been the frequency that the large trees come down in winter wind storms. The Northwest Gallery took a major hit two years ago when a middle-aged Douglas Fir crashed into the roof. Last year a dead branch fell among some school kids exploring the rock pile. Nobody was hurt, but we didn’t want to go through that again.
We contacted the Oregon Department of Forestry (ODF) for insights and explained our concerns centered on safety and environmental management, rather than an economic boost. During a lengthy tour, ODF Stewardship Forester Kevin Nelson from the Forest Grove office walked the entire 28-acre property with us, and told us some of his concerns.
The large stand located south of the Northwest Gallery has multiple problems. Dubbed the “Compromised Stand,” it has served as overflow parking for major events, which, in retrospect, was not a good idea. Years of parking cars there has compacted the soil and damaged the tree roots, resulting in unhealthy trees. Several of the larger trees displayed signs of significant rot. The younger trees underneath appeared stunted and in poor health. ODF approved removing most of this stand to convert to dedicated parking.
The trees growing at the bottom of the lawn, dubbed the Front Yard stand, are in good shape, so no action is required there.
The Southwest Stand appears to be in good shape as well, but in serious need of thinning, and showing signs of distress. Our ODF contact stipulated that he would not sign off on high-grading the good wood out of that stand; instead, he advised an “addition by subtraction” approach to remove rotting or undersized leaners, fixing crowded spots, etc. He also advised against keeping some of the larger trees along the edge of the stand that threaten the main museum building. He pointed out a thriving section of Western Red cedar that he recommended leaving as-is, and believes we’ll end up with a truly park-like setting when the job is complete.
With all the permits in place and consultations concluded, Salmon Creek Construction began removing the compromised stand on February 8. They immediately confirmed our worst fears: many of the larger trees were weak and dangerous.
In addition, we have some up-to-date advice for the rest of the acreage to the north, which was logged and replanted with Douglas Fir with mixed success many years ago. ODF advised against restocking any more Douglas Fir seedlings, due to extended droughts and changing climate. Way back in Oregon Territory history when Joe Meek homesteaded on the property directly west of the museum, Douglas Fir was a dominant species across the Tualatin Plains. Now, foresters recommend replanting with an Oregon variety of Ponderosa Pine, which is much more resistant to drought. Since six out of the last ten years have experienced drought-like conditions through the summer, he was concerned that we would waste our time stocking with Western Redcedar or Douglas Fir. So we’ll be removing 60-70 unhealthy trees from the front, and replanting with about 300 Ponderosa Pine seedlings in the back, with a mix of local oak. We’ll retain the oak habitat, with a long-term goal of creating some nature trails for public use.
We are sorry to see the trees go, but it was time to act. We anticipate Salmon Creek will be done with the Compromised Stand very quickly weather permitting), so patrons shouldn’t be affected once the trees are down and we turn the slash pile and stumps into much-needed chips. The plan is to address the Southwest Stand from the back, via the service road, further reducing impact to the public. Once the logging is complete, we can apply for a permit, hire an engineering firm to address grading, and lay down a thick bed of gravel in time for our major events this summer.
