We're really not sure where the name for this trail comes from, perhaps at one time it was Nasty.
At this point though it is a pretty sweet winding trail through the trees with only one ledge just before a hairpin (on the way up) that proves particularly difficult. On the way down you'd just ride off it. I guess it could be nasty if you clipped a tree because you were going too fast on the downhill. Otherwise this is a nice ride up from the bigger ponderosa trees of Otero Canyon
to the pion pine and scrub oak forest up on the ridge to the east.
