Cloverdale sits at the western edge of this landscape, where the Russian River winds through the northern reaches of the Alexander Valley. The terrain rises sharply to the east into the Mayacmas Mountains, a region defined by steep canyons and prominent heights like Pine Mtn and Pocket Peak. This transition from the river valley to the high ridges is marked by a network of rural roads, including Old Crocker Inn Rd and Swiss Colony Rd, which hint at the long-standing agricultural and viticultural identity of the Asti area.
