Notes
Rode to Erwin, then did a bit more than 1 1/2 loops, rode back. Loop measures a bit over 7.5 miles and mini-loop from upper parking lot (down into creekbed) back to upper parking lot (just after trailhead) is a bit over 5 (cut expert loop out on mini-loop). Good ride, but I didn't feel all that comfortable with the trail... hard to get a good pattern going... some good moments, some not so good.
