The Hamburg WMA has an interesting past. Some details about his WMA can be found here. Like most WMAs, there are a number of unmarked trails within its borders. Capturing a waypoint before you begin your search and where you decide to leave a trail is recommended. The challenge is trying to select the proper trail to the cache area. Of course you could just bushwack to the cache, but judging from the terrain it might not be easy.
The cache will take you to the high point of Hamburg Mountain, 1200'+, with a great view of numerous ridges to the southeast. Lake Mohawk can be seen in the distance. From certain vantage points, a small portion of the Kittatinny Ridge/Mt. Tammany is visible, as well as Jenny Jump Mt. on a clear day. This is a great place to bring a lunch!
The cache is a full size ammo container. Have fun!
