1955 Map of Sunshine Peak

About this map

Lava Mountains and the surrounding high desert terrain dominate this mid-century survey of the San Bernardino interior. The landscape is characterized by extensive volcanic deposits and notable geological formations such as Pisgah Crater, situated near the northeastern boundary. Evidence of early to mid-20th-century resource extraction is found throughout the area, with several mining operations indicated, including the Silver Cliff Mine, National Lead Mine, and Imperial Lode Mine. These sites suggest a history of prospecting for lead, silver, and other minerals in these isolated heights.
