Distinct crux sections on this traverse are encountered going into and coming out of both the central and west alcoves. Each alcove provides options to either remain low and underneath a roof, or reach out of the roof and climb the lip/roof edge. All options end high and work back down on 5.10+ terrain. It is possible to traverse from left to right, but the standard traverse starts upstream and traverses to the left. For a true endurance test, try the out-and-back.
Upstream of Mosquito Bridge. The start is marked by a large boulder, climber's right of the bridge cracks.
Maybe a pad or spotter. Landings are on flat rock.
