2023 Map of Jumbo Mountain

About this map

The Sawtooth National Forest dominates this high-elevation landscape where the South Fork Boise River carves through the northern reaches of the quadrangle. The terrain is a complex network of steep drainages, including Big Water Gulch and Weeks Gulch, which feed the river system. Settlement is sparse, represented primarily by the Deer Park area near the center of the sheet and the South Fork Ranch Airport in the northwest corner. The map documents an extensive system of wilderness travel routes, such as the Skeleton Creek Trl and the Iron Mountain Trl, which provide access to peaks like Jumbo Mtn and Iron Mountain. These trails follow the natural contours of the Soldier Mountains and Sawtooth Mountains, tracing the historical pathways used by forest rangers and backcountry travelers before modern road development was established.
