Seigler Springs and several other mineral springs define this landscape on the border of Lake and Sonoma Counties during the late 1950s. The region is characterized by a concentrated resort and mining economy, where settlements like Loch Lomond and Whispering Pines sit alongside industrial sites such as the Big Chief Mine and Thorne Mine. The complex topography of the Mayacmas Mountains is detailed through numerous peaks including Cobb Mtn and Seigler Mtn, which towers over the Collayomi Valley.
