Solution to the puzzle will provide you three digits for North and three digits for West to replace .000 in posted coordinates. Cache container is a silver bison tube in pine bush about chest height.
Infrastructure
One of the great qualities of infrastructure done well is we don't think much about it. Only when something goes wrong do we even notice there is something to complain about.
Electricity is a great example, until it isn't working we really do not consider all the people and behind the scenes effort that goes in to allow us to plug anything in anywhere.
GPS infrastructure is key to us geocachers. We hold our devices in our hands and wander through the trails seeking out a secreted location, hardly ever thinking about what it has taken to put those satellites into space and keep the signals flowing to feed our needs.
Each morning (most of us) hop into the shower at roughly the same time and all get a reasonable flow of water raining down upon us, without considering how much water pressure is needed to keep that water flowing. We pass by water towers in our towns that have blended into the scenery much more effectively than such large towers should on an island with relatively flat terrain.
On your geocaching adventures, as you drive from town to town across Long Island, take a moment to recognize the infrastructure you take advantage of and appreciate those that put in the effort to make it so you don't even have to know such jobs exist.
We recently started looking for water towers we pass, as they are easy to spot if you want to notice them. We found that most water towers are also Benchmarks as they are tall, prominent and well defined points used as part of triangulation networks. (No need to triangulate for this puzzle)
Here are eight days of our logs of water towers that we encountered or tried to encounter.
- Day 1
- Day 2
- Day 3
- Day 4
- Day 5
- Day 6
- Day 7
- Day 8
Now that we discovered they are benchmarks, we should start logging our water towers as we do our caches!

You can validate your puzzle solution with certitude.
