Cave Tours Open Friday - Sunday 10am-5pm | Howe High Adventure is Closed for the Season
New Clear Bag Policy in Effect. See Details Below.
Purchase a bag of mining rough, and make your way to the water sluice. A water sluice is a trough of running water where bags of mining “rough” are emptied and sifted through screen trays. The water washes away the dirt, revealing sparkling gems and minerals. You are panning for earthly mineral treasures (if not gold)! You will discover garnets, rose quartz, fool’s gold, emeralds, aquamarines and many beautiful natural stones. You can use the identification charts to accurately identify exactly what you have unearthed. Try your hand at sifting for fossils or arrowheads. And remember, all the treasures you find, are yours to take home!

Once you’ve found your gemstone treasures, there are other hidden treasures waiting for your discovery! There are ancient volcanic geodes. Select your natural geode, and watch as we carefully cut it in half to reveal its inner world of mineral beauty.
Geodes are usually spherical hollow rocks containing crystalline structures that vary in chemical compound, size, color, density and internal shape.
Geodes are mysterious. It is impossible for one to know what’s on the inside until your Geode is cut open! The formation of geodes is still scientifically unconfirmed – another mystery! Each geode offers a unique glimpse of the spontaneous beauty that nature can generate with the earth’s minerals over time.
Geodes are priced by size from $6.00 (1-2″ diameter) to $45.00 (6-8″ diameter) You receive both halves of your cut geode. Prices do not include taxes as applicable.
