Rimrocks

The Rimrocks are towering sandstone cliffs that run for miles along Billings, rising sharply above the Yellowstone River and overlooking the city below. These massive formations create a dramatic natural boundary between the river valley and the surrounding landscape.

These cliffs formed roughly 80 million years ago when the area was the shoreline of an ancient inland sea. Over millions of years, the Yellowstone River carved and shaped the rock layers into the steep walls visible today.

Local Native American nations viewed these cliffs as sacred locations for rituals and watching over the land. The sites remain deeply meaningful in the spiritual life of these communities.

Several parks and trails along the formation provide different access points for visitors of varying fitness levels. Wear sturdy footwear and plan your visit during spring or fall when temperatures are more comfortable for walking.

Early European traders used natural crevices within the sandstone for shelter during harsh winters in the 1800s. Researchers later discovered remnants of these temporary dwellings hidden within the rock formations.
