Special Considerations
- The mountain passes at Reservation Ridge on US 191 in Utah and Douglas Pass on CO 139 in Colorado can be treacherous during winter storms. These roads are rarely, if ever, officially closed but sometimes a few hours delay would be prudent.
- All points along the Diamond are subject to snowfall with snow cover lasting longer in the northern and higher elevation areas than in the lower elevation and southern portions.
- Dinosaur trackways are difficult if not impossible to see under snow cover.
Restrictions
- The Cleveland-Lloyd Dinosaur Quarry is closed during the winter months.
- Cleveland-Lloyd Dinosaur Quarry is at the end of 13 miles of gravel road that is accessible to family sedans in all weather except deep snow.
- The Mill Canyon Dinosaur Trail and Copper Ridge Dinosaur Trackway can be reached by a couple miles of dirt road, accessible to two-wheel drive vehicles in good weather but not advisable for the same vehicles in wet weather.
- Tour buses are not able to reach Mill Canyon Dinosaur Trail and the Copper Ridge Dinosaur Tracksite.
