1. New Deal in Colorado. The Works Progress Administration (WPA), which focused on giving people jobs rather than providing direct relief, employed tens of thousands to make civic improvements. Together the CCC and the WPA built the 10,000-seat Red Rocks Amphitheater near Morrison in the foothills west of Denver, and the WPA constructed Alameda Parkway to link the theater to Denver.

3. Dinosaur Ridge History. In 1937, during the construction of West Alameda Parkway, dinosaur tracks were discovered on the east side of Dinosaur Ridge in the 100-million-year-old rocks of the Dakota Group, representing the Early Cretaceous Period. Because these strata represent the shoreline sediments of an ancient seaway that was frequently trampled by dinosaurs, these beds have been called the “Dinosaur Freeway.” (Submitted on September 3, 2020, by Cosmos Mariner of Cape Canaveral, Florida.)

6. Rattlesnake at Base of Marker
Having photographed many thousands of historical markers, across 3 decades, in all 50 states and in several other countries, this one represents the only time I found myself in danger. Going in for the marker close-up, I found my self face-to-face with this large rattlesnake! Fortunately, the polite critter chose rattling, rather than striking, as its greeting behavior!
