This multi-cache will bring you to two scenic lookout points at Mission Island Marsh. At both the posted coordinates and the second waypoint, there are lookout binoculars. You will need to note the silver numbers on both of these binoculars. One of the numbers is 3-digits and the other is 4-digits. First, divide both of the numbers by 1000. Next, add the result for the 3-digit number to the north coordinates supplied below and subtract the result for the 4-digit number from the west coordinates supplied below:
N48 21.607
W089 14.045
The final cache is a short walk away and provides another scenic view. Please cover the cache up well to avoid detection. Have fun!
