About this adventure

The Rice Northwest Museum of Rocks & Minerals, located in the pine forests north of Hillsboro, is presented as a top geological science collection. This weekend, a special family day event is planned, featuring 'Geode Cracking' and a 'Little Fossil Hunter' activity. Children may choose an unopened natural geode and, with the help of a professional technician, use a hydraulic rock cracker to open it, keeping the sparkling amethyst or calcite crystal clusters found inside. In the dinosaur fossil exhibit hall, a treasure hunt checklist can be used to search for trilobites, dinosaur egg fossils, and a rainbow fluorescent mineral darkroom. The main building and exhibition halls have smooth ramps for stroller access. The museum also provides spacious family restrooms with changing tables, and an outdoor pine forest picnic area is available. This event is suggested for young explorers curious about geology and gemstones.
