1969 Map of Dolphin Island East

About this map

Dolphin Island and the western reaches of the Great Salt Lake define this stark 1969 orthophotomap of Box Elder County. Unlike traditional line-drawn maps, this survey utilizes an orthophotomosaic composed from 1966 and 1969 aerial photography, providing a photographic rendering of the shoreline and the expansive Mud Flat regions. The data records a specific moment in time, noting a Great Salt Lake elevation of 4,193 feet as measured in November 1966. This specialized survey was compiled with technical contributions from the U.S. Naval Reserve and the U.S. Corps of Engineers, focusing on the desolate interface where land and salt water meet. The absence of roads or trails emphasizes the isolation of this corner of the lake during the late 1960s.
