OSHR 1815 - Geologic Field Excursion: Larimer County Foothills

  • Noncredit

This course is offered through the Osher Lifelong Learning Institute (OLLI) at Colorado State University. You must be a member of Osher to enroll in this course.

This one-day field excursion is designed to examine a variety of geologic features and rocks in the Northern Colorado Front Range Foothills. We will examine and discuss the origin of sedimentary, metamorphic, and igneous rock units ranging in age from Precambrian to Cretaceous. We will also view and discuss the origin of large-scale structural features such as hogback and folded rock strata that formed during the mountain-building episode that created the Front Range Uplift. Our trip will begin near Carter Lake Reservoir, west of Loveland, and proceed north to Owl Canyon along U.S. 287 with stops along the way.

(NOTE: This Geologic Field Excursion is designed for non-geologists who have a basic understanding of geologic processes and rocks from a basic geology course or from personal reading and study. The ability to hike up to about one mile round trip at several stops is required).

Noncredit courses do not produce academic credit nor appear on a Colorado State University academic transcript.
