A cache near the summit of Gunstock Mountain. The cache is a camouflaged lock-n-lock hidden in an obvious place. In terms of size, it's between a small and a regular.
This cache was formerly located about a quarter-mile off the Ridge Trail, but recent trail construction has created a blue-blazed trail within 100' of GZ. Find this cache astride the old Gunstock iron mine, roughly a mile uphill from Belknap Mountain Road and a quarter-mile downhill from the Ridge Trail. Expect moderate-to-steep grades with a few great views towards Winnipesaukee and Squam!
At GZ, you will find a channel cut into the ridge. This is the iron mine from the 19th century, and there is another cut just like it a little further downhill, past a fire pit. Although there are no open shafts, please remain conscious of your surroundings, and have fun at your own risk.
The cache is a camouflaged lock-n-lock with some swag inside. This cache is not supposed to be difficult, so don't overthink it.
A good trail map can be found here.
Congratulations to kleine_t on the FTF!
