items needed for a safe hike

Visitor safety is a high priority at Fossil Butte National Monument. Report safety hazards to an employee or volunteer.

When hiking, wear sturdy, comfortable hiking shoes, carry plenty of water and protect yourself from the sun and insects.

Avoid hiking during thunderstorms. In sagebrush country you become a lightning rod. Lightning can be dangerous as far as 10 miles away.

Mosquitoes, deer flies, horse flies and wood ticks are bothersome in the spring and summer months. No need to worry about rattlesnakes, they do not live here.

Do not approach or feed wildlife.

Railroad workers played a major role in the discovery of fossils from the Green River Formation. In the late 1860's, Union Pacific workers uncovered the first major fossil fish beds (Lake Gosiute) near the town of Green River, Wyoming.
