About this map

Henrys Lake and its surrounding high-country basin define this 2011 survey of the Island Park area. The northern waters of the lake are regulated by the Henrys Lake Dam, which feeds the meandering Henrys Fork southward across the wide, alluvial expanse of Henrys Lake Flat. This landscape is shaped by recreational and conservation interests, evidenced by the expansive Henrys Lake State Park and the Island Park Golf Course near the settlement of Flat Rock.

Canyons and peaks provide significant relief to the west and east, including Garner Canyon and the prominent Mount Two Top. A network of forest roads and trails, such as the Two Top Snowmobile Trl and Bootjack Pass Rd, provides access to these higher elevations and remote basins like Stamp Meadows. These features illustrate the area's transition from a historic water-resource hub to a contemporary mountain recreation destination.
