WALK THE RIDGE WITH A GEOLOGIST
Join a Professional Geologist for a tour of DINOSAUR RIDGE for a 2 ½ hour walk and discussion of the geology and changes of the Denver area through time. The season’s first walk is May 4, 9:15am at the Visitor Center, 16831 W. Alameda Parkway. You will be transported by van from the Visitors Center to the west side of DINOSAUR RIDGE for a 1 ½ mile walk back. Physically the first quarter of a mile gains approximately 100 feet of elevation. The remainder, 1 ¼ miles, of the walk is downhill.
Your tour leader will explain the Precambrian – Fountain Formation Unconformity located across the valley in Red Rocks Park, the missing rocks and life in between the Precambrian and the Pennsylvanian time, the dinosaur fossils and environment of formation of the Jurassic Morrison Formation, the volcanic ash bed in the Cretaceous Dakota Formation, why there are oil and gas deposits in the Denver Basin, the dinosaur tracksite that developed along a swamp section of the Cretaceous beach, the tidal channel and associated life along other stretches of that same beach, and finally the Cretaceous interior seaway that extended across Colorado from the Artic Ocean to the Gulf of Mexico. Your leader will use maps that show how North America and Colorado fit into a global pattern of movements with the assembly of the supercontinent Pangea that allowed world-wide migration of dinosaurs to our continental dispersal of today.
These tours are designed for adults. The charge is $10.00. For reservations call 303-697-3466x103 or email firstname.lastname@example.org by noon the Friday prior to the walk. Walks will be the first and third Saturdays of May through October of 2013.
