To find this cache, you will need to find the tune that has the phone number in it. From those coordinates, go 460 feet straight west, then go 40 feet straight north. I give the offset this way so that it will be easy to do with a GPSr. Though going straight from the coordinates to the cache may not be the best route to take.
For the puzzle coordinates, put the phone number in these coordinates: N 41° 20.XXX' W 112 0X.XXX'. You can check your answers for this puzzle on Geochecker.com.
I don't think that hunting is allowed in this particular area, but I did find some spent shotgun shells. However, during most of the year you will want to bring your 'skiter guns, or at least repellent. The ground is uneven, so it is definitely not wheelchair accessible, but you may be able to lift a stroller across the uneven parts.
