About this map

Register Rock serves as a prominent landmark along the Snake River in this mid-1980s landscape of southern Idaho. The map reveals a geography defined by the impounded waters of Lake Walcott and the ecological expanse of the Minidoka National Wildlife Refuge. The terrain is marked by distinctive geological features like Janes Nipples and the steep passage of Lake Channel Canyon, which contains the small Bonanza Lake.

Traces of local history and infrastructure are visible through labels like Quigley and several water sources such as Mowers Spring and Morgans Waterhole. The area's development is indicated by a Double Wooden Power Line and a large Pipeline cutting across the high desert, while river access is noted at a dedicated Boat Ramp. This survey provides a clear look at the intersection of protected wilderness and utility corridors during the late 20th century.
