This is a Bonus cache for the Adventure Lab - Dams of the Blackstone
You must complete the Adventure lab, and each successful stage will give you a digit for the north and West coordinates for this bonus
Use the Format 41.AB.CDE -71 VW.XYZ to solve for the final cords for the location of the bonus cache
This bonus cache brings you to Pratt Dam the 6th and final dam in this series -
The walkway at the posted cords is built on the stanchions of an old railroad trestle that was washed away in a flood.
Pratt Dam was built in the 1880's to create a holding pond called new pond which was used to store water to power the Ann & Hope Mill, the Lincoln Mill, and the Lonsdale Company mill.
Once you have completed this Adventure lab and this final you will have visted 6 of 18 current dams on the Blackstone River.
