About this map

Knowles sits as a primary settlement point in this Sierra Nevada foothill landscape, where the local economy and geography were long defined by granite extraction. Evidence of this industrial history is visible at the Raymond Quarry and Madera Quarry, while the surrounding terrain is marked by prominent peaks such as Buford Mountain and Lilley Mtn. The Fresno River serves as a central artery through the quadrangle, with notable points of interest including the Fresno Crossing and a Gaging Sta.

Downstream, the development of the Hensley Lake reservoir highlights the management of water resources in this part of Madera County. To the southeast, the San Joaquin Experimental Range indicates a legacy of land use study, while the Red Top Lookout stands watch over a complex system of drainages like Coarse Gold Creek and Wild Hog Canyon. This survey, updated with 1978 data, captures the shift from traditional quarrying and ranching toward modern water infrastructure.
