Origin: Alluvial gravels of the Yellowstone River and its tributaries between Sidney and Billings, Montana, USA

Description: Montana Agate was actually formed in the Wyoming area of Yellowstone National Park. Locals walk the river banks and collect it. There are also a couple suppliers that pay high school kids and pwd's to collect it. They are paid by weight. 

It is a unique rock because it is well known in North America, yet not commercially mined- only surface picked.
