Old Abandoned Mining Shaft

What a great day to go out cacheing. A wee bit to much snow on the ground still, but we ventured out anyways.
We started out with this one. Now we looked and looked for something that
looked like a mining shaft. I'm pretty sure Tracy was looking in the right place as far as that goes. To me it looked more like a old ground level tree house. But I wasn't the one over there looking, I was zeroing down on the cache, which of course I found!!!
(the pictures suck, cause I had the camera on the wrong setting, but it will do)
