Based on Late Cretaceous fossil evidence found along this trail, this area was a delta with lakes, streams and a mosaic of swamps, scrubby forests, palm tree thickets and small open areas. Impressions of logs, leaves and palm fronds suggest a warm, humid climate similar to that of the Gulf Coast today.
Animals in this painting include: Triceratops protecting her young from Tyrannosaurus rex, a wading bird, and a mammal clinging to a tree stump.
This is North America at the time the Laramie Formation was being deposited about 68 million years ago. A shallow seaway was receding from the interior of the continent. The future state of Colorado is highlighted.
