2012 Map of Jamison Ridge

About this map

Round Valley and the surrounding high country of Mendocino County define this 2012 survey, where the Middle Fork Eel River carves a deep path through the landscape. This area is characterized by isolated homesteads and ranching history, evidenced by Thrash Ranch, Marks Place, and the extensive Eden Valley Ranch to the south. Local heritage is rooted in the early settlement of the region, anchored by the Pioneer Cem near the northern edge of the map. High ridges and distinctive peaks, such as Jarbow Ridge, Jamison Ridge, and Negro Head, dominate the topography between the drainages of Eden Cr and Salt Cr. The presence of several remote water sources like Redwine Spring and Jarbow Spring points to the vital importance of water management in this high-elevation terrain.
