Geocache Description:

The cache is not at the posted co-ordinates. The posted co-ordinates are for a location where you can find the answers that you need.

We've long been intrigued by the Milford and Manchester Railroad that was only in use for a few short years.

This cache is placed near the old railroad bed in Milford, NH as it headed northeast into Amherst. You'll encounter at least three artifacts from that old railroad when finding this cache.

I entered the woods at the Trailhead waypoint and there the start of a trail of a sort at that location. Note that you'll need to cross active railroad tracks to get from the parking to the trailhead but the railroad is used very infrequently, nonetheless please be careful and look both ways before crossing the tracks.


At the Posted Co-ordinates (PC) you can stand on an artifact from the railroad and to the north you can see another similar railroad artifact. Both of these similar artifacts are made up of native rectangular objects (my guess is that the objects came from Milford). You'll need information about both of those artifacts (as well as a third railroad artifact - see below) to solve the puzzle and get the final co-ordinates. There is a drop at the PC so keep a hand on any very young kids.

The final co-ordinates are at: N 42 49.ABC W 071 37.DEF


A: The number of objects that make up the top course of the artifact at the PC.

B: Add 2 to the number of objects that make up the top course of the artifact at the PC.

C:Number of stones making up the floor of the stone platform on the left when facing the river at the PC minus 2.

D: If XY is a two digit number equaling the number of steps up the northwest side of the artifact at the PC (the side to the left when facing the river and the other artifact), then D is equal to Y plus 3.

E: The number of courses above the stone platform on the left when facing the river at the PC plus 1.

F: The top course of the artifact at the PC has a number of objects that are laid out parallel to the artifact that is north of the artifact at PC. The number of parallel objects is F.

Please replace the cache exactly as found, thanks!


Congrats to wemedge and nhgoldens on being FTF!


There is some trash at the PC but it isn't overwhelming. If you remember, please bring a trash bag and pick up any trash that you can. Thanks!
