The Rice Northwest Museum of Rocks and Minerals is a non-profit museum in Hillsboro, Oregon, United States. Located just north of the Sunset Highway on the northern edge of Hillsboro, the earth science museum is in the Portland metropolitan area. Opened in 1997, the museum’s collections date to the 1930s with the museum housed in a home built to display the rock and mineral collections of the museum founders. The ranch style home is listed on the National Register of Historic Places, the first of its kind listed in Oregon.
The museum sits on 23 wooded acres (9.3 ha), with the main building containing 7,500 square feet (700 m2) of space. Collections include petrified wood, various fossils, fluorescent minerals, meteorites, zeolites, and a variety of other minerals. With more than 20,000 specimens, the museum is the largest of its kind in the Pacific Northwest. The facility has around 25,000 visitors each year, many of whom are on school tours.
The Rice Museum offers a variety of public programs, including hands-on classes for children where participants make necklaces out of rocks. It hosts an annual summer festival with events such as thunderegg cutting and demonstrations of gold panning. The facility has hosted the Northwest Fossil Fest. The museum offers tours for school groups and other youth programs, often handling multiple groups each day. Children in the school tours get to select a stone to take home from a pile outside. The museum is open Wednesday through Sunday.
The museum and grounds are located on the north side of the Sunset Highway west of Portland between the Helvetia Road and Jackson School Road exits. Situated on 23 acres (9.3 ha) of mostly forested land, the museum is housed in the historic Richard and Helen Rice House, built as a single family residence. Completed in 1952, the home was built of Arizona flagstone on the exterior and wood native to Oregon, including curly maple and myrtlewood.
