1991 Map of Terrace Mountain East

About this map

Terrace Mountain dominates the western edge of this Box Elder County landscape, its steep contours rising sharply from the surrounding basins. This 1991 revision, based on aerial photography from the late 1980s, captures a stark, unpopulated expanse where the high desert meets the extensive salt flats and playas characteristic of the region. The map is defined by the vast area labeled simply as Mud, representing the ephemeral lake beds and saturated alkaline soils that spread across the eastern and southern portions of the quadrangle. The lack of infrastructure, settlements, or even unimproved roads throughout the central sections of this survey suggests a terrain that remains largely impassable or restricted by the harsh environmental conditions of the Great Salt Lake Desert basin.
