1977 Map of Highland Springs

About this map

Adobe Creek winds through a landscape of high ridges and narrow valleys in this orthophotomap of Lake County. Unlike traditional topographic sheets, this aerial perspective provides a photographic view of the dense vegetation and drainage patterns across the local Mountains as they appeared in the late 1970s. The contrast between the undeveloped high ground and the geometric grid of cultivated fields in the east illustrates the sharp transition between the region’s wilder uplands and its agricultural valley floor. Researchers can use this photographic data to study land use and brush cover during a period of significant regional mapping by the U.S. Geological Survey.
