About this map

Loomis sits at the foot of the eastern Cascade foothills, serving as a gateway to the steep ridges and deep draws of Okanogan County. The topography is dominated by massive landforms like Douglas Mtn and Gold Hill, which overlook a network of seasonal and permanent watercourses including Toats Coulee Cr and Sinlahekin Cr. Much of the southern portion of the quadrangle is dedicated to the Sinlahekin Deer Winter Range and Wildlife Refuge, protecting the valley floor and lower slopes.

Modern recreation and historical access routes converge here, most notably where the Pacific NW National Scenic Trail winds across the high ground near Rattlesnake Mtn. The landscape is etched with the names of early land use and geographical landmarks, from the high Olie Pass in the north to Hercules Flat and Doney Basin further south. Small mountain lakes like Jim Black Lake and Ryan Lake provide water sources in this high-relief terrain, while the Sinlahekin Valley remains the primary corridor for movement and settlement.
