Geocache Description:
A mystery cache located in Troy, NH. You will need to solve the puzzle with clues from the Troy Common to get the final coordinates.
Take a walk around the Troy common to learn some history of the town, and the soldiers who fought from here. In order to get the final coordinates, you will need to solve a puzzle based on information you gather from inside the common. There is no need to leave the fenced in area for any of the clues (although you may have to for the final cache – we will never tell!). Parking is available at several locations around the common – the suggested parking coordinates are only one of many options. Bring a writing utensil, some scrap paper for taking notes, and a calculator (or your brain) to figure out math problems! 😉 We hope you enjoy the cache and learning more about Troy!
Final coordinates are: N42 AB.ACD W72 DD.EFG
A. The total of the first two numbers in the year the monument “The Defenders of the Union” was erected, minus the last two numbers of the year. (For example, 2014 would be 20-14.)
B. There are two monuments on the common that mention names of Troy residents who served their country in various wars. Those who died while in service have special recognition on the monuments. Count these soldiers’ names, and add the total number from both monuments.
C. Find the year that the Troy Common was established. Add all four digits of the year and divide the total by five.
D. How many gazebos are located on the Troy Common?
E. Find the monument that says which two towns donated land for the town of Troy. Count the letters in each of the two town’s names to figure out X – Y, if X is the name of the first town and Y is the name of the second.
F. Count the total number of granite fence posts that line the common. Add one to the total number, and divide this by twenty-four.
G. Find the year that the Town of Troy was settled in. G is the second to last digit in the year.
This cache is placed in memory of Elmer Gladding, former Police Chief of Troy, NH. He was a major contributor to this town that he loved so much, and you can find his granite fence post at the northern end of the common, as well as one dedicated to him by his daughter Traci and another by his daughter Sandi. Elmer passed away exactly 24 years ago from the date this cache was placed. RIP Cowboy Cop and your lady!
