An easy multi stage cache. The coordinates do not have a physical cache, but is where you need to start. First, locate the sign of the cache title and look for two years. Subtract 1577 from the first year to get XXX of the N coordinates. Then subtract 1653 from the second year to get YYY of the W coordinates.
The final cache is at N 42° 42. XXX W 112° 25. YYY
Cache is a bottle hanging in a lone juniper. BYOP!
