for those without google earth(it's free), here's a description of where the above trail is.
riding the typical wma loop counter clockwise, you hit some rolling hills with slickrock sections. then you come to a very loose, gravelly, short climb. at the top of this short climb, turn right. you can't miss the trail, the trailhead is huge. continue straight on this, descending. when you can see the swampy area in front of you, bear left about 3/4 of the way down the slope, on a visible old road. ride across an easy technical section(just pedal), then left up the hill. this will bring you to the powerlines, where you will again turn left to meet up with the usual loop, at the top of the dreaded powerline climb, which you are cleverly avoiding.
