Frequently Asked Questions: 

Can I pay for admission at the gate?
No additional admissions will be sold once this event is sold out. This event is very popular and we recommend online ticket reservation (for members) or purchase (not-yet members) as early as possible.

Do we need to be there at a certain time to hunt the eggs? 
No! To redeem for a prize, you need to find four plastic eggs of certain colors (based on their location on the property, the “egg zones”). That eliminates the “mad dash” of other egg hunts and keeps it fair! You can show up any time in your admission window and we promise there will be eggs hidden.

Can adults participate?
Absolutely! Children of all ages are welcome to participate at the Rice Museum.  Everyone loves a good egg hunt.

Do adults have to pay if they’re not participating?
Yes, your $8 covers your admission to the museum regardless of if you choose to hunt eggs. That price is reduced from our $12 general admission.

If I’m in the AM group and I show up at 12:30, can I stay past 1:00?
Yes. You’re welcome to stay as long as you’d like once you’re admitted.

I’m in the PM group but I showed up at 12:30 to get in line, can I come in?
No. You will not be able to park or enter the grounds until 1 PM so we can minimize traffic congestion.

Can I bring my own thunder eggs from home and have you cut them?
No. Our volunteers are here to cut thunder eggs from this event only. Please ask for a recommendation for local cutters if you have your own thunder eggs to cut.

Do you sell food?
Limited snacks will be available for purchase at our hospitality table, so bring your own lunch or plan to grab it from one of the fabulous nearby restaurants. Keep in mind, we do not allow food or drink inside the museum.

Major Oregon Meteorite finds new home at the Rice Museum

The Rice NW Museum of Rocks and Minerals recently acquired the famed Morrow County meteorite, a 40-lb. specimen discovered by Donald Wesson in 1999 in Morrow County, Oregon. The cone-shaped space rock was already on display as part of a loaned exhibit, but is now a part of the permanent collection.

The Morrow County meteorite is noteworthy as an oriented specimen, meaning it did not tumble as it fell through Earth’s atmosphere. Instead, it settled into a fixed position, much like NASA’s famed Apollo spacecraft as they returned to Earth. The exterior of the Morrow County meteorite has distinctive flow lines left behind as heat from its fiery passage through the atmosphere melted away its surface.  It also has a distinctive yellowish color due to weathering.

There is a notable anomaly to the Morrow County specimen. There is speculation that the tip of the meteorite’s cone was broken off when farm machinery encountered it. More recently, scientists sawed off a large section from the base to aid in identification.

The Morrow County meteorite is of great interest to scientists.  A team of researchers at The Cascadia Meteorite Laboratory (CML) at Portland State University positively identified the rock as a meteorite.  Further research by CML scientists Melinda Hutson, Alex Ruzicka, and Dick Pugh revealed that the Morrow County meteorite was once part of an asteroid that collided with another object 460 million years ago.  The collision produced multiple fragments, one of which would eventually become the Morrow County meteorite after its journey to Earth.

Morrow County Meteorite
The Morrow County meteorite was discovered in 1999 by Donald Wesson and his wife Debbie. They discovered the interesting rock in a ditch, carried it home, and stored it in various places, including under their deck barbecue. A television show about meteorites inspired Mr. Wesson to take the rock to a local county fair in Castle Rock, Washington in 2009, and a member of the Southern Washington Mineralogical Society referred him to Western Washington University geologists in Bellingham, Washington. Ultimately, the Cascadia Meteorite Laboratory at Portland State University confirmed the specimen as an L6 ordinary chondrite. There is no known crater associated with the Morrow meteorite. 

“This is fantastic news for Oregon collectors and meteorite enthusiasts,” noted executive director Julian Gray. “We have been trying to acquire this specimen for years, and we are especially proud to be able to bring this specimen ‘home’ to Oregon. This important acquisition reinforces the Rice Museum’s commitment to the Pacific Northwest rockhounding community and to the preservation of scientifically important specimens. We hope that stories like the discovery of the Morrow County meteorite will spur other collectors to find the next Oregon meteorite.” he added.

Gray also expressed thanks to the Rice Museum curator. “This was a great trade. I want to express special thanks to curator Leslie Moclock, who completed the trade with famed mineral collector Ed Thompson. We appreciate Ed’s dedication to our museum.”

Camp del Cielo meteorite
The Campo del Cielo group of iron meteorites was discovered in 1576 in northern Argentina by the Spanish military in response to Native legends. Indigenous people in the area had been using iron collected from the area for many years to fashion into weapons, and called the place Pigueum Nonralta, which the Spanish translated to “Field of Heaven,” or Campo del Cielo. Subsequent expeditions in 1783 and 1803 verified that the material was not iron ore, but a meteorite. By 1969, scientists had located a 26 impact craters in a strewn field measured about 2 miles wide and almost 12 miles long. The largest single piece unearthed was named Gancedo, for the nearby town that aided the excavation, and weighed about 31 tons. The el Chaco fragment, named for Chaco province, weighed almost 37 tons, and the combined mass for the field is over 100 tons, which if intact, would have made it the largest such mass in the world, ahead of the 60-ton Hoba meteorite of Namibia. Examination of charred wood from beneath larger Campo del Cielo specimens yielded an impact date of about 4,000 – 5,000 years ago. The metallic composition of the Campo fragments is 92.6% iron, 6.7% nickel, with cobalt, phosphorous, germanium, gallium, and iridium also present. Specialists classified the Campo del Cielo meteorite as a coarse octahedrite to granular hexahedrite, group IAB.

The museum also acquired a new 125-pound Campo del Cielo iron meteorite specimen, and it, too is on immediate display. The two new meteorites were traded for the museum’s 200-lb. Gibeon meteorite specimen, a common iron meteorite from Namibia. The Campo del Cielo iron meteorite is an interesting addition to the museum’s “hands-on” display, because unlike many mineral specimens, the Campo actually benefits from human contact. The surface, when first discovered, tends to be rusty and can flake. The oils in our skin, combined with handling, tends to clean and polish the surface. “The oil from human hands is like magic for the care and curation of any Campo Del Cielo,” Thompson explained. The museum invites visitors to explore the entire meteorite collection to learn more about these fascinating rocks from space.

Donor-Sponsored School Tours Top 1,000 Students for 2018

Nothing fills a museum with energy like school children on field trips. It’s always a pleasure to hear them marvel at our various exhibits of rocks, minerals, fossils, meteorites, gold, and gems. Thanks to the generosity of our donors, Rice Northwest Museum of Rocks and Minerals is proud to offer financial aid for qualifying schools and keep those hallways packed. With the end of the year rapidly approaching, we thought it would be a good time to update our followers about the program.

For background, the program began two years ago with a gift from a new benefactor. In 2018, we raised additional funds at the annual Benefit Dinner, specifically earmarked to help subsidize school trips for in-need communities. Qualifying schools may visit the museum, or we can send offsite programs to their classrooms. The goal is simple – to make sure kids of all backgrounds can experience how we can make earth science education fun. 

Schools can receive up to 75% of their program fees to be covered by our donors, based on the percentage of students who qualify for free and reduced lunches. To date this year, the museum subsidized 19 school visits, mostly for grades 3 and 4, and served over 1,100 kids.

School buses line up adjacent to the Northwest Gallery. We like to see these buses all the time!

This week, a group of 5th graders made the trek from the Centennial School District, on the far east side of the area Rice NW Museum serves. The students learned about the rock cycle, how minerals form, how fossilization occurs, about mining, and about the volcanoes and earthquakes common in our region. 

Museum Educator Ramona Radonich prepares the students to enter the museum. 

If you would like to learn more about donating to the program, you can find more information on our Donations page.

To book a field trip or classroom visit to the Rice NW Museum for your school, please visit the For Teachers page and fill out the program form. We can review your financial aid status after you fill out the booking form. We are accepting reservations through June 2019 and look forward to seeing your students, so sign up today!

Thank you for another amazing year.

Thank you for your continued support. Because of you, we were able to develop rich and relevant exhibit content, fund financial aid for schoolchildren, facilitate community events, and create engaging programming and innovative experiences for guests of all ages within and beyond the walls of the Museum. Thanks to our supporters, 2018 was a truly incredible year.

The mission of the Rice Northwest Museum of Rocks and Minerals is to engage, inspire, and educate generations on the splendor and complexities of our Earth.

Last year, we demonstrated that together we have the power to accomplish many goals. Here are a few ways in which we fulfilled our mission in 2018:


• Record breaking attendance at the Museum and all events: 33,000 visitors and counting.
• Created bilingual exhibits to reflect the diversity of our community.


• Sponsored hundreds of kids to bring programs to Title I schools, improving access for students who otherwise might not get to experience the Museum.


• Reached more than 9000 school children on field trips to the museum.
• Community outreach at festivals and events around the Pacific Northwest.
• Taken our STEM programming into dozens of schools in the Portland area.

What’s next?

We are proud of the tremendous progress we have made together, both at the Museum and in the community. Now, it is time, through your support, to make 2019 even better. We rely on your donations to help keep our future fresh and vibrant. While admission fees and museum store purchases cover our operating expenses, we rely on donations for new exhibits, events and programs, and for reaching thousands of school children every year on field trips.

Your investment will be used wisely. While continuing to care for our collection and historic building, we want to upgrade our exhibit cases and security system in order to make the most of the Smithsonian Affiliations loan program and to borrow from other outstanding collections from our friends around the country.

We call upon all donors now to join us on our mission to engage, inspire, and educate generations on the splendor and complexity of our Earth! There are many ways to support the museum. There are many ways to give. Donate online or contact us now to donate in another way. All donations are powerful. Please give what you can today. Thank you, we look forward to seeing you often at the Rice Museum.
