It is renowned for its exceptional fossil deposits, specifically the mesmerising Painted Hills, which is one of the three units in the park.

One can get a glimpse of fossils of opossums, oreodonts, sabre-toothed tigers, and turtles by visiting the Clarno unit of the monument. These remnants serve as a reminder of the dynamic and fascinating history our planet holds.
