This would be an impossible run.
This unmarked trail leaves from a small cairn, just after the Upper Piney River Trail
begins to parallel the river itself. This trail is difficult to follow at times, especially during the spring months when it's wet and overgrown. Keep in mind, however, that as long as you keep the small, unnamed creek to your right, you're on the right path.
The trail is incredibly steep at times, especially near Kneeknocker Pass. For those who do not like loose talus scrambling, this trail is not for you.
This trail can be very densely snow-covered in spring; it might be worth bringing your ice axe if attempting this in early-spring/summer.
Many, many wildflowers.
