Geology Quick Fact


Welcome to the Wyoming State Geological Survey’s website. Within these web pages, you will find information about Wyoming’s vast geologic, mineral, and energy resources. Whether you are looking for industrial data, facts for a weekend of rock hounding, or general education on geology, you can rely on the scientists at the WSGS. I would like to take this opportunity to invite you to visit the survey building in Laramie where you can preview publications or visit with the staff. I hope you find this website useful and enjoyable.
