About this map

Sixteenmile Cr cuts through the northern reaches of this Gallatin County landscape, carving the prominent Sixteenmile Canyon along the border with Broadwater County. The terrain transitions from the high elevations of the Horseshoe Hills in the south toward the expansive Ellison Flat to the east. This 2017 survey reveals a network of named drainages and hollows, such as Roy Gulch, Poison Hollow, and Whiskey Gulch, which define the local topography.

Water sources are vital markers in this arid region, with numerous named points including Townsend Spring, Dunbar Springs, and Eastham Spring scattered across the township. The infrastructure is characterized by remote access routes like Clarkston Rd and Pole Gulch Rd, which connect isolated homesteads and grazing lands. These features collectively illustrate a ranching and wilderness character, where geographic landmarks like Big Davis Gulch and Lone Pine Gulch remain the primary points of orientation.
