Iron Mountain is a high mountain peak at an elevation of 3.082m (10,111ft) above the sea level, located in Sweet Grass County, in the U.S. state of Montana. It’s one of the highest mountain roads of Montana.
The road to the summit, located within the Custer Gallatin National Forest, is gravel, rocky, tippy and bumpy at times. It’s called Picket Pin Creek Road. The road is usually impassable from October to June (weather permitting).
Great trail for experienced wheelers. Avoid driving in this area if unpaved mountain roads aren't your strong point. 4x4 vehicle required. Stay away if you're scared of heights. Expect a trail pretty steep. Wet conditions may make for tough driving along the muddy road. This area is threaded with ATV and old mining roads.
