We were introduced to the Crystal Hills a few years back. It was the first time we visited Polemi and we were on the hunt for geocaches. This particularly one was a near perfect example of what makes a good cache: an interesting location that we would have been unlikely to find had there not been a cache there. The only thing that let the cache down was it's size, but we won't go into that here. Instead we shall have a look at the terrain, and see why the cache was called "The Crystal Hill".
