About this map

Sedro-Woolley and the meandering Skagit River anchor the northern reaches of this mid-century survey, where the valley floor transitions into the high timberlands of the Cultus Mountain range. The region's industrial and residential development follows the Northern Pacific railroad corridor, connecting lakefront settlements like Montborne, Big Lake, and McMurray. Along the river, a Levee and Skiyou Island show the engineering and natural features of the Skagit floodplain.

Upland terrain is defined by extractive and recreational landmarks, from the Gravel Pit near Day Creek to the Grandview Recreation Center near the Stillaguamish River in the south. Genealogists and historians can trace the legacy of timber harvesting through the numerous notations of Old RR Grades and the Spar Tree Trail winding around Frailey Mountain. The map also captures the remote Lake Cavanaugh community before more modern subdivision, surrounded by peaks like Bald Mountain and Haystack Mountain.
