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.

The Types Of Geodes Found In Montana

The world abounds with different types of this natural wonder, and the price of a geode depends on its variety. Here in Montana, you can mostly find geodes that are lined with drusy Quartz and rimmed with black and white fortification Agate.

Pryor Mountains

Pryor Mountains is a hidden gem that’s tucked away from the hustle and bustle of city life. It’s located in the southern part of our state, not too far from the Wyoming border. Its geography is pretty diverse, with rolling hills, steep cliffs, and a mix of deciduous and coniferous trees.
