2018 Map of Tacna

About this map

Tacna sits at a critical junction of desert transportation and irrigation history, where the Union Pacific Railroad and Interstate 8 parallel the ancient course of the Gila River. The landscape is a study in desert water management, featuring the engineered path of the Mohawk Canal and the Colfred Floodway, which protect the small settlements of Tacna and Colfred from the erratic flows of the Mohawk Wash. In the southwestern corner, the terrain shifts abruptly from the flat agricultural expanses of the Mohawk Valley to the sharp elevation of the Baker Peaks. This 2018 survey captures the precise layout of local access roads such as Gila Levee Rd and E Mohawk Canal Rd, providing a clear view of how human habitation is structured around these vital water and transit corridors.
