This is a puzzle cache, so it is not at the posted coordinates. Nor are the posted coordinates a good place to stop.
When you find the cache, take note of how it is placed and replace as found to preserve the find for the next cacher. Make sure to bring your own pen or pencil, tweezers might help too.
Now for the puzzle... N51 ? W114 ? So you are looking for the rest.
Are you ready ?
1, 2, 3.... GO!
Enjoy the walk to the cache !
