Walk With a Geologist at Dinosaur Ridge

Walk with a Geologist at Dinosaur Ridge Trail is a 2.5-hour (1.5 mile) walking tour of the East and West sides of Dinosaur Ridge led by a professional or amateur geologist. In addition to the interpretation of the dinosaur track and fossil sites, the tour includes an in-depth discussion of the geology and changes of the Denver area through time. All walkers require a ticket to be transported via shuttle bus to the starting point. This tour is designed for participants ages 16 and older.

This enhanced walking tour 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 track site 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 Arctic 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 resulting in our continental dispersal of fossils today.

Tour Guides

Al Kleeb has had lifelong interest in both geology and paleontology which brought him to volunteer at Dinosaur Ridge a little over ten years ago. He has worked closely on local scientific projects with such internationally known geologists and paleontologists as Nora Noffke (Old Dominion University) and Martin Lockley (Professor Emeritus, CU Denver). Recently, Al has joined the Preservation Committee and has taken on the task of staining the tracks on the track site and implementing a program to train other volunteers to participate in track-staining, including through use of ropes and rappelling.

Larry Lens is a retired oil and gas geologist with 32 years at Amoco and BP. He has also been working with PetroSkills and continues to do contract teaching. Larry started volunteering with Dinosaur Ridge in 2020 and enjoys inspiring young people to be scientists by leading public tours, school programs and greeting our visitors every Wednesday in the exhibit hall as a docent.

Bob Mason is also retired from the petroleum industry where he worked for 42 years as an exploration geologist and has studied geology all over western US from Alaska to New Mexico, with emphasis on sedimentary rocks. Bob has been leading tours with us since 2019 and says that he “thoroughly enjoys teaching anyone of any age about the geology/paleontology of Dino-Ridge”.

Kermit Shields received his geology degrees and spent his professional career with Mobil Oil in a variety of production and exploration jobs in both domestic and international offices. After retiring, he became an active volunteer at both the Denver Museum of Nature and Science and at Dinosaur Ridge. Kermit was an active Board Director with Friends of Dinosaur Ridge from 2006-2021.

Bill Stone received bachelor and master of science degrees in geology and spent a career in the petroleum industry, exploring for and developing oil and gas reserves in the U.S. Bill began guiding tours at Dinosaur Ridge in 2018 and loves sharing its geological wonders with everyone.
