2011 Map of Twin Sisters

About this map

Twin Sisters defines the high northern landscape of this Idaho quadrangle, presiding over a complex network of drainages that feed into the Little Weiser River and Squaw Creek. The 2011 survey reveals a territory primarily shaped by forestry and water management, evidenced by the many Forest Service routes like NFD 818 Rd and NFD 853 Rd that penetrate the canyons. This map is particularly notable for identifying the Third Fork Project Camp, situated near the confluence of Third Fork Squaw Creek and several steep-walled features such as Bear Gulch and Buck Canyon. The geography here is marked by significant topographical landmarks like Mill Creek Summit, which serves as a natural divide between the north-flowing Mill Creek and the southern watershed. Named features such as Lava Gulch, Woodard Gulch, and Four Bit Creek provide specific points of reference for those tracing local place names or exploring the drainage patterns of Gem County.
