I first thought of a wilderness cache technique while hiking West Snowmass Creek and implemented it in the original version of this cache. Unfortunately, that technique was unworkable, so I came up with a new mechanism and have redesigned the cache.
Physical waypoints are not allowed in the Wilderness, so Photo waypoints are used. Proceed to each of the Reference waypoints and determine which of the photos below was taken at the waypoint. The selected photo will give you the coordinate digit.
The Reference waypoints are in the order you will encounter them as you walk up the trail. Photos are ordered by the associated digit value. I recommend you print out all the photos for reference. There is no cell service up here. (Obviously, there are quite a few photos you will not use!)
Cache is at N 40 05.ABC W 105 34.DEF
The physical cache is outside the Wilderness, within 1200 feet of the trailhead. After gathering your information, take a seat at the picnic table and work out your solution.
