Hellgate Campground in Montana. Ringed marker is this site; the other dots are the 803 public campsites we map in Montana.
Hellgate Campground is located 30 miles east of Helena, Montana, along Montana Highway 284. In July of 1805 the Lewis and Clark Expedition traveled through the Canyon Ferry area exploring and mapping the Missouri River. When Lewis visited the area he described it as a beautiful and extensive plain country of about 10 to 12 miles wide which extended upwards further than an eye could see.
