2012 Map of Mount Wilson

About this map

Mount Wilson Observatory stands as the crowning landmark of this San Gabriel Mountain landscape, overlooking a dense network of suburban development and canyon trails. The map highlights the sharp transition between the residential grids of Pasadena, Altadena, and Arcadia and the steep wilderness of the Angeles National Forest. This 2012 survey illustrates the critical infrastructure managing the region's hydrology, including the Eaton Canyon Reservoir and an extensive series of debris basins such as the Sierra Madre Debris Basin and Santa Anita Debris Basin. Historic recreation sites and summits like Echo Mountain, Mount Lowe, and Inspiration Point are documented alongside local institutions like William Carey International University. The presence of the Sierra Madre Cem and various golf courses provides valuable points of reference for genealogists and local historians tracking the modern layout of these established Los Angeles County communities.
