Lake Cavanaugh and its surrounding peaks dominate this 2017 survey of the borderlands between Skagit and Snohomish counties. The landscape is defined by significant elevations including Mt Cavanaugh, Frailey Mtn, and Stimson Hill, which overlook a complex drainage system fed by Pilchuck Cr, Grant Cr, and Crane Cr. In the southern portion of the quadrangle, the terrain descends toward the North Fork Stillaguamish River valley, where the small settlement of Cicero is situated.
