Geo-caching challenge

At this time of year, the grey squirrel is incredibly busy, running up and down trees, running madly around woodland, risking life and limb crossing busy roads, all in a frenzy to collect as many nuts as possible as they rain from the skies.  Autumn is indeed bounteous on the nut front, and squirrels behave as if they are on Supermarket Sweep.
What to do with so much food?  Evidence of them eating as many as possible is everywhere, with half eaten nuts strewing the paths.

But they can also be seeing hiding them in caches.  Squirrels do not hibernate but they may sleep for long periods in the winter.  When they wake up, they will be hungry, and their well-developed spatial memory, as well as their excellent sense of smell, will lead them straight to breakfast.
