This a two step cache.
At these coordinates you will find a utility pole which has a 2 digit metal number. The two digit number on the pole represents the thousandths of the minutes that you must add to the following coordinates:
N 42° 34.477 W 71° 19.491
Once you have added the pole number to these coordinates you have the cache location! You can park at the pole. Note that from the parking area you can walk to the cache along trails without having to bushwhack until the last 50 feet or so. The cache itself is a plastic detergent bucket.
