About this map

The geologic legacy of the Henrys Fork Caldera and Island Park Caldera dominates this portion of Fremont County, where the Henrys Fork river winds through a landscape shaped by volcanic history. The 2017 survey reveals the intricate hydrologic network feeding the region, including the Buffalo River, Toms Creek, and the headwaters at Big Springs. Settlement patterns are defined by the corridor of the Old Highway (Macks), which connects the communities of Island Park and Trude.

Infrastructure markers such as the Macks Inn Substation and various forest service access points like the Moose Cr Sh Area illustrate the modern management of the Targhee National Forest. The map also preserves the memory of the area's railroad history through labels for the Island Park Siding and Trude Siding. This detailed record provides a clear view of how recreational access and forest management coexist within a unique geological basin.
