About Billings, MT

The downtown core and much of the rest of Billings is in the Yellowstone Valley, a canyon carved out by the Yellowstone River. Around 80 million years ago, the Billings area was on the shore of the Western Interior Seaway. The sea deposited sediment and sand around the shoreline. As the sea retreated, it left a deep layer of sand. Over millions of years, this sand was compressed into stone known as Eagle Sandstone.
