2015 Map of Sly Park

About this map

Jenkinson Lake serves as a central hydrological landmark within this portion of the Eldorado National Forest, where the waters of Sly Park Creek and Hazel Creek converge. The landscape is defined by the transition from established residential enclaves like Lakewood Sierra and Sierra Springs in the northwest to the more isolated settlements of Grizzly Flat and Happy Valley in the south. This area preserves a legacy of historic transportation corridors, including the legendary Pony Express Trail and the Mormon Emigrant Trail. The terrain is deeply incised by drainages such as Woodpecker Gulch and Shingle Mill Gulch, reflecting a history of timber and resource extraction. High points like Baltic Peak and Grizzly Peak overlook the winding North Fork Cosumnes River, illustrating the complex topography that shaped early El Dorado County development.
