About this map

Las Mariposas and the surrounding Sierra foothills define this landscape during a period of active gold mining and early conservation. Surveyed in 1909 and 1910, the map records the industrial footprint of the region, from the Texas Flat Mine near Coarse Gold to the Standard Mine and various marble quarries. The settlement pattern reflects a mix of mining camps, ranching outposts like McFarland's Ranch, and an Indian Settlement on Fresno River.

Transitioning into the high country, the map shows the southern edge of Yosemite Natl Park and the rugged timberlands where Clarks Mill and Sugar Pine operated. Transportation is dictated by topography, with the Mono Trail and Chilnualna Trail providing access to the peaks. The presence of numerous remote schoolhouses, such as Indian Peak School and Oakvale School, illustrates the spread of small communities across the Chowchilla River and Fresno River watersheds before the era of modern reservoirs.
