What Are Montana Geodes?

Geodes are rock formations with crystal-lined cavities. Found in different parts of the world, they typically form in sedimentary rocks and are created by mineral-rich groundwater that seeps into existing rock cavities. Over time, the minerals crystallize and form beautiful patterns inside the cavity. Montana’s unique geology is suitable for this!
Geodes come in various shapes and sizes, ranging from small, round rocks to large, oblong-shaped formations that can weigh over 100 pounds. The crystal formations inside them can also vary greatly, with some featuring delicate needle-like crystals, while others having larger, multi-colored formations. These natural wonders never fail to fascinate and intrigue anyone who gets a chance to find them.
To make your geode hunting a bit easier, we created a brief guide on geode identification that you can use.
