Gravel Segment
On NF-37, Winthrop, Okanogan County, Washington
pavement ends at elevation of about 3200 feet (approximately 7 miles from the East Chewach road bridge over the Chewach River). The first mile uphill is moderate. Then the next 1.5 miles are steep (10-11%) with some washboard. You get a slight break after that, but the road contiunues up at about 5-6%.
