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.

Colorado is rich in energy, mineral, and water resources that society has found to be useful and valuable. These resources include oil, natural gas, coal, coal bed methane, metal deposits, industrial minerals, construction materials, gemstones, surface water, ground water, and geothermal. The total production value of oil and gas in 2014 was $15.8 billion, and the mining industry added $7 billion.

In this course, we will examine Colorado’s rich history of exploration and mining, the types of resources available, and their geographic distribution and geologic origin. This is a natural follow-up course to Geology and Geological History of Colorado, or a stand-alone course.

Please Note: No Class November 22
