Continuing our Geocache saga…
Last time we “hid” our Geocache “treasure” we had a pretty good idea where it could be found relative to visual landmarks: as long as the Ash tree and the corner of the yellow brick building are still there. If we publish our map the pirates will certainly find our treasure or will they?
Today we check our Geocache sites with the GPS and record the coordinates that represent latitude and longitude right down to the thousandth (precision is the best medicine in this activity!). Now we can assign coordinate values to the position of our treasures on a two dimensional map such as a sheet of graph paper should we choose to be real serious about mapping. We can see where all our treasures are located relative to landmarks in the environment and one another’s treasures. We can clear the memory on the GPS. Now we can use our master map to enter the precise coordinates into a fresh GPS. The point of the exercise now is to find our treasures and see how well we are able to complete our Geocache exercise. “Treasures Ahoy Matey!”
