1964 Map of Jumbo Mtn

About this map

The South Fork Boise River winds through this high-elevation landscape on the border of Elmore and Camas Counties, where the Soldier Mountains meet the Sawtooth National Forest. This 1964 field-checked survey highlights a remote wilderness defined by a network of drainage systems like Iron Creek and Beaver Creek, and punctuated by landmark peaks such as Jumbo Mtn and the Iron Mtn Lookout. The river corridor provides the primary hub of human activity, featuring a string of riverside recreation sites including Baumgartner Campground, Bighorn Campground, and a Hot Spring near the mouth of Jumbo Creek. Inland, the terrain is traversable only by a series of high-mountain routes, labeled as Pack Trail and Jeep Trail, which connect isolated features like the Gardner Gulch Corral and the small alpine Heart Lake. Further south, the map identifies the Deer Park area and the point labeled Bremmer near Stewart Creek.
