Road Risks and Hazards

There are many dips along preserve roads that often follow historic telegraph or railroad routes.

Use roads at your own risk.

Many dirt roads lead to isolation. They do not lead to visitor centers, cell phone service, hotels, stores, or gas stations. Depending on the time of the year and the roads you are on, you may not see another vehicle the entire time you are out there.

While very rare, people have died here while many others were rescued just in the nick of time. They didn't fully appreciate the risks, traveled in a vehicle not equipped for the conditions on a remote, seldom traveled road, or didn't let anyone know where they were going. They lacked a satellite communication device to call for help and didn't pack enough equipment, warm clothing, food, or water.

Do not overestimate the capability of your vehicle. Some roads are fine for stock high clearance 4x4 pickups and SUVs. Third party tow bills often reach hundreds or thousands of dollars. Rangers are happy to provide you advice about a trip plan or to discuss your equipment. Contact Us

Always assume the road will get worse ahead. If it gets too rough for you, turn around!

Hazards may be on the roadway or next to it. Keep an eye out for potential hazards while driving in the preserve.

Potential Road Hazards

Current conditions: Due to the sheer size of the region and the number of roads in the preserve, it is not possible to provide updated travel conditions. Expect and be prepared for poor conditions. Don't go if it looks bad or rain is forecast. For official updates, check the Road Conditions page.

Summer Weather: During the summer monsoon season (June - September), it is better to travel in the morning. Storms usually occur after 1pm and can totally wipe out roads.

Winter Snow and Ice: Planning on travel in areas above 3,000 feet? Check road conditions with a ranger. Roads at this elevation may be saturated from rain or snow and impassible.

• There are very few people to help you if you break down.
• Temperatures can drop well below freezing. The short days of winter surprise hikers who may need to finish their hike by headlamp.

Cattle: This is ranch country. Expect cattle standing in the road on blind corner and especially in the dark. Black cows on a moonless night have resulted in many accidents where people were driving too fast for the conditions.
