1991 Map of Dolphin Island East
USGS Topo · Published 1991About this map
Gunnison Bay dominates this late-twentieth-century study, showcasing the fluctuating shoreline and remote landscape of the northwestern Great Salt Lake. The terrain is defined by the isolated Dolphin Island on the western edge of the quadrangle, where topographic contours reveal the subtle elevation changes of this desert island. This 1991 revision, based on aerial photography from the 1960s and 1980s, focuses on the hydrologic and geological characteristics of the region, noting a base water Elevation 4200. The absence of roads or human settlements emphasizes the harsh, saline environment of northern Utah, making it a critical reference for understanding the natural history and shifting water levels of the basin.
