1968 Map of Bonnie Claire

The topography transitions sharply from the level Alkali Flat and its scattered Wells to the steep eastern slopes of the Grapevine Mountains. Near the northern border, the curiously named Coyote Holes mark a rare water source in a region defined by arid depressions and dry lake beds. The presence of these specific landmarks among the surveying benchmarks provides a clear view of the sparse but persistent infrastructure required for desert survival and mineral processing in the late 1960s.
