2015 Map of Lone Tree Creek

About this map

Lone Tree Creek and its many tributaries carve through this California landscape, defined by sharp ridges and deep canyons at the intersection of San Joaquin, Stanislaus, and Alameda counties. The massive Hetch Hetchy Aqueduct cuts across the northern terrain, a critical piece of water infrastructure that contrasts with the natural hydrology of the area's many seasonal springs, such as Lone Tree Mineral Spring and Sulphur Springs. High elevations are marked by landmarks like Mt Oso in the southeast and Cedar Knob, while the intricate network of gulches including Sulphur Spring Gulch and Buckeye Gulch illustrates the complex drainage patterns feeding into Hospital Canyon. Named ridges like Pegleg Ridge and Smiths Ridge offer a detailed view of the regional topography, while family or locally named features like Buzzard Roost South Ridge and Callahan Gulch provide specific points of interest for local history and geographic study.
