Southwest Wyoming offers two seasons: summer and winter.  To participate in ranger-led activities, schedule your visit between the Memorial and Labor Day holiday weekends.  Allow all day to fully explore the park.

Fossil Butte National Monument is located between 6,800 and 8100 feet elevation in the sagebrush covered hills of rural, southwestern Wyoming.  Wide open spaces, fresh air, blue skies, abundant wildlife and, of course, some of the most incredible fossils in the world are found here.
