Dillon Pass is one of the panoramic viewpoints on Badlands Loop Road in Badlands National Park. The different strata of rock can clearly be seen, many of them rich in fossils. These strata, from newest to oldest, include:
- Sharps Formation (28 to 30 million years) - wind, water and volcanic deposits forming the jagged peaks of many of the formations.
- Rockyford Ash - the bottom layer of the Sharps Formation formed by volcanic ash.
- Brule Formation (30 to 34 million years) - brownish formations from the Oligocene Epoch containing some paleosols (fossil soils) and sandstone from a time when the land was covered by prairie.
- Chadron Formation (34 to 37 million years) - greyish deposits at the time when the seas retreated and temporary rivers flowed across the land. These deposits can contain alligator, titanotheres and other mamal fossils. The deposits have eroded into low, rounded mounds.
- Yellow Mounds - lying below the Chadron Formation the Yellow Mounds were exposed during the uplift of the Rockies and formed of ocean mud.
Shale (69 and 75 million years) - oldest of the Badlands formations deposited during the Cretaceous Period when a large shallow ocean covered the Great Plains. These deposits contain many marine fossils, clams, ammonites, and sea reptiles.
