Sugarloaf Ridge dominates the eastern landscape of this Sonoma County survey, where the peaks of Mt Hood and Bald Mtn rise above the drainage of Sonoma Creek. The map documents a blend of residential growth and preserved terrain on the eastern edge of Santa Rosa, including the planned community of Oakmont and the historic Pythian Home Cemetery. The lower elevations reveal the geothermal and hydrological character of the region, featuring Los Guilicos Warm Springs and the ecologically significant Ledson Marsh.
