kg), was combined with the Rice Museum's existing pieces. The log is from Eastern Oregon and is estimated to have lived more than 15 million years ago. The petrified wood specimens come from Oregon, Washington, and as far away as Argentina and Australia. Other fossils include those of cycads, palms, and ferns. The main rhodochrosite attraction is the "Alma Rose" from the Sweet Home Mine in Colorado. The Alma Rose includes crystals measuring up to 9.5 cm in length along with quartz and calcite highlights. The Rices once owned the complementary "Alma King" rhodochrosite from the same mine, but sold the piece to the Coors Brewing Company, who then donated it to the Denver Natural History Museum. The two stones had been purchased by the couple for US$800,000. Other rhodochrosite specimens include those from mines in Arizona. The museum also has a collection of 107 gold pieces from the F. John Barlow collection featuring items such as a 42 troy ounce (1.31 kg)) leaf and pieces mined from the Ace of Diamonds mine in Liberty, Washington. One of the museum's pieces, a sperrylite from Russia, is considered one of the finest in the world. Individual items on display include coprolite from Mongolia, a 500-pound (227 kg) piece of the lightweight volcanic rock pumice, obsidian and basalt. One specimen on display is a wide plate with clear quartz crystals, epidote crystals measuring as large as 10 cm and translucent calcite scalenohedrons, and comes from Green Monster Mountain on Alaska's Prince of Wales Island. The collection includes a cycad fossil dating from the Jurassic era that weighs 500 pounds (227 kg). One meteorite is the Gibeon meteorite which weighs 210 pounds (95 kg) and came from the African nation of Namibia. The world's largest known opal-filled thunderegg, weighing 1.75 tons (1600 kg), is housed at the museum. The thunderegg is Oregon's state rock. Other items include azurite, Oregon sunstone, amber, copper crystals, zeolites, morganite, and agate among others. Programs The Rice Museum offers a variety of public programs. It once hosted 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 also offers tours for school groups and other community groups. These events will resume if staffing and funding increase. Facilities The museum and grounds are located on the north side of the Sunset Highway west of
