Start from the Mayflower Gulch
parking area. Just a hundred yards or so up the trail, it opens up with a spectacular view of Fletcher Mountain. From here, find a good place to cross the creek on your left and make your way up to an aqueduct north of the creek. This aqueduct is frequented by snowshoers and other winter travelers, so it's pretty easy to find. Follow this all the way around the west side of Mayflower Hill until you reach the next drainage, which is Humbug Creek.
