2013 Map of Bottleneck Lake

About this map

Craters of the Moon National Preserve dominates this arid interior landscape of Minidoka County, illustrating the complex volcanic geology that defines the region. The map reveals a delicate water management system where small, isolated catchments like Pronghorn Reservoir and Lower Thumb Reservoir collect rare runoff. These water bodies are often the only markers of activity in a terrain otherwise characterized by its intricate contour lines and expansive, undeveloped blocks. The northern portion of the preserve is marked by Bottleneck Lake and Three Forks Lake, providing vital hydrographic detail for those studying the natural drainage patterns of this high-desert environment. This 2013 survey is particularly useful for identifying the specific township and range boundaries, such as t4s r24e, which help orient researchers in this otherwise sparsely labeled wilderness area.
