Historic Quarry Trail

Most hikers complete this 2.5-mile (4 km) loop trail in about 1 to 2 hours. The duration can vary based on your fitness level, acclimatization to the high altitude, and how much time you spend exploring the quarry site and reading the educational exhibits.

The Historic Quarry Trail is generally rated as moderate to strenuous. This is primarily due to the significant elevation gain of nearly 700 feet (213 m) and the high altitude, which can make breathing more difficult and increase the risk of dehydration. It's not suitable for wheelchairs or strollers.

The trail is primarily a dirt path, generally wide enough for a single file line. You'll traverse parts of the Wasatch and Green River Formations. There's a short, steep side loop to the historic fossil quarry, which includes several flights of stairs. This section can be steep with uneven footing. The trail also cuts through a talus slope of loose rock, so careful footing is required. In spring, snowmelt can make it very muddy.

Yes, dogs are permitted on the Historic Quarry Trail. However, they must be kept on a leash no longer than 6 feet at all times to protect wildlife and ensure the safety of other visitors.

Parking is available directly at the trailhead within Fossil Butte National Monument. You'll find restrooms, water, and a small picnic area conveniently located at the trailhead for your use before and after your hike.

Fossil Butte National Monument does not charge an entrance fee. Therefore, you do not need a permit to access the Historic Quarry Trail or other areas within the monument.

The trail offers different experiences throughout the year. Spring can be very muddy due to snowmelt, while summer can be very hot with no shade, requiring plenty of water. Fall offers cooler temperatures and potentially pleasant hiking conditions. In winter, it's accessible for snowshoeing, though it may be difficult to follow when covered in snow. Consider your tolerance for heat and mud when planning your visit.

Given the desert environment and high elevation, it's crucial to bring plenty of water, wear sunscreen and a hat for sun protection, and consider bug spray during the summer months when mosquitoes can be present near hidden streams. Sturdy hiking shoes are recommended due to uneven terrain and loose rock.

Despite being in a desert environment, the trail offers expansive views of the surrounding landscape, including the distinct Wasatch Formation and vast seas of sagebrush. The quarry site itself provides great panoramic views. While fossils aren't visible directly on the trail, wayside exhibits provide fascinating information about the park's geology and paleontology, connecting you to the ancient freshwater lake that once covered the area.

Yes, due to the high altitude and lack of shade, dehydration is a risk, so carry ample water. It's also advised to avoid hiking during thunderstorms, as the butte tops are prone to lightning strikes. Always stay on marked trails and be mindful of uneven footing, especially on the steep sections and talus slopes.

The Historic Quarry Trail is a loop trail, allowing you to experience different views and geological formations as you complete the circuit.
