Mount Heliograph is a high mountain peak at an elevation of 3.060m (10,039ft) above the sea level, located in Graham County, in the southeastern part of the U.S. state of Arizona. It's one of the highest mountain roads of Arizona.
The road to the summit, located within the Coronado National Forest, is gravel and rocky. It’s impassable in winters. Avoid driving in this area if unpaved mountain roads aren't your strong point. 4x4 required. Stay away if you're scared of heights. Expect a trail pretty steep. At the summit there’s a fire lookout tower built in 1934.
