2024 Map of Island Park Dam

About this map

Island Park Reservoir dominates the landscape of this portion of Targhee National Forest, where the waters of the Henrys Fork are held by the Island Park Dam. The geography here is defined by immense volcanic features, including the Island Park Caldera and the Henrys Fork Caldera, illustrating the complex geological heritage of Fremont County. To the north, the Eastern Centennial Mountains rise above the basin, with drainage through Sugar Creek and Mill Creek. Local settlement and recreation are centered around Island Park and residential areas like I P Bills Island. Tracing the varied road networks, such as Kilgore Yale Rd and Old Shotgun Rd, reveals the transition from valley floor to the high terrain of Thurman Ridge and the Centennial Mountains.
