1984 Map of Gifford Spring

About this map

The Wapi Lava Flow dominates the northern landscape of this Idaho quadrangle, showcasing the stark volcanic geology characteristic of the Snake River Plain. This 1984 provisional survey documents a region defined by the transition from these lava beds to the fertile riparian environments of the Snake River. At the water's edge, the Minidoka National Wildlife Refuge encompasses the southern reaches, protecting the diverse habitats of Lake Walcott and Tule Island. Human activity in this arid environment is centered around critical infrastructure and isolated outposts, such as the settlement of Wapi along the rail corridor and the remote DeWoff area. The presence of Gifford Spring and numerous wells highlights the ongoing importance of water management in a terrain also marked by Shifting Sand and the prominent Bonanza Bar.
