From the parking lot, the summit is only about 3.5 miles, a good portion of which is on a groomed cross country ski trail. Sometimes you may not be able to drive all the way to the trailhead, so make sure you park out of the way, and DO NOT TRESPASS. From the Trailhead, travel north and slightly downhill into Middle Fork basin. You will pass several houses along this cross country ski trail. Just past Yellow Mountain, turn east off the groomer. You will be heading up a tight canyon, it is best to gain a slight bench on the north side of this feature, about 100 feet above the creek. Keep heading slightly left with Wilson in front of you. Soon you'll pop out at the bottom of the slide path and it will be straight forward form there.
