Alma Rose Video - the "Alma Rose" from the Sweet Home Mine in Alma, Colorado is a magnificent specimen the Museum is privileged to have on display. The Alma Rose includes crystals measuring up to 9.5 cm in length along with quartz and calcite highlights. The Rices once owned the "Alma King" rhodochrosite from the same mine, but sold the piece to the Denver Museum of Nature & Science.

The two were purchased as a "couple" for nearly $1 million USD. The Museum shows a wonderful video on the discovery and mining of this specimen in the Museum's Video Presentation Room.

Video Presentation Room - watch a 10 minute video on mining rhodochrosite or view and touch the various types of rocks that make up the earth.

Reference Library - Rudy Tschernich and others have donated countless hours accumulating, consolidating, organizing, restoring, indexing and making available hundreds of books, guides, manuals, magazines, and other reference materials for member use. For 50 years the primary reference materials (prior to recent additions/consolidation) have been utilized and continue to be available for viewing, study, and research to museum members interested in the earth sciences.

Rock Pile - the museum maintains a huge rock pile full of treasures, such as agates, petrified wood, jaspers, thundereggs, obsidian, quartz crystals, marble pieces, fluorescent specimens, and more. The pile is constantly changing with frequent donations from local rock hounds and collectors.

Every student that visits the museum may select his or her own special "free" rock, which gives them a hands-on experience in the world of rock collecting. The surplus and larger rocks are available during business hours at a per pound rate.

Geologic Walk - large specimens of basic and unusual rocks are arranged on the grounds. See a 4,800-pound basalt column, a 5,000-pound sandstone boulder, gigantic pumice, thunderegg, petrified wood, a 2,700 lb. boulder of Biggs Jasper from the China Hollow Mine and rocks from the Missoula flood.

Largest Opal-Filled Thunderegg in the World - The Northwest Minerals Gallery is home to the World's Largest Opal-Filled Thunderegg, found right here in the state of Oregon.
