2020 Map of Thatcher Hill

About this map

The Bear River meanders through the heart of Gentile Valley, marking a landscape where high-desert agriculture and rugged terrain meet at the border of Caribou and Franklin Counties. The valley floor is defined by a complex network of irrigation and infrastructure, including the Gentile Valley Canal and several local roads like River Road and Gentile Valley Road that follow the natural contours of the water. To the west, the topography rises sharply into the Portneuf Range, characterized by deep incisions like Left Fork Mill Canyon and Right Fork Mill Canyon. Local history is anchored by the Thatcher Cemetery and the presence of the W E Ranch Airport, suggesting a sparsely populated ranching community. The map also documents geographic landmarks such as Thatcher Hill and Gem Valley, providing a detailed look at the land use and drainage patterns of this southeastern Idaho corridor.
