1962 Map of Illinois Hill

USGS Topo · Published 1981

About this map

Mining operations and rugged foothills define this Mariposa County landscape during the early 1960s. The map reveals a high concentration of gold-era activity, evidenced by the Great Northern Mine, Pocahontas Mine, and the Klondike Mine nestled near Illinois Hill. These sites, along with the San Jose Mine and Goodview Mine further south, reflect a legacy of extraction that shaped local geography long before modern photogrammetric mapping.
