The Marsh Creek 1 and Marsh Creek 7 properties rise from Marsh Creek, extend up over the foot of a woodland ridge, and wrap around the northeastern mouth of Cakebread or “Marsh Canyon.”
The parcels are part of two important wildlife corridors—a grassland corridor that connects Black Diamond Mines Regional Preserve southeast to Round Valley Regional Preserve and the Los Vaqueros Watershed; and a stream corridor that extends along Marsh Creek.
