Don't let the hour approach keep you away, it's a beautiful hike up the beaver dam creek drainage. The best approach is to park at the Box Canyon parking area. From there, cross the river, and find a trail on the east side of the river heading upstream. The trail continues along the river until it turns uphill up a small drainage. Take this trail until it almost crests a ridge, and head off-trail directly east over the ridge crossing two trails. Head down the other side of the ridge into the meadow. In the meadow, an old trail that services some mining claims begins just south of a large boulder (pic included) in an aspen grove and follows a dry creek bed. Follow this trail uphill until it peters out. Traverse across and up the hillside, remaining on relatively easy and sandy ground until you are directly downslope of the formation. Continue a bit farther past, before heading up the some slabby, cascading rocks. Once you are pretty close to the base, head back left to the base of the cliff.
