Who's hole?

In our many adventures at park W, this one was very interesting. While we were exploring around our campsite looking for a monkey colony, we came across this big hole. This hole was actually a den and was very large, Mark could have easily climbed into it with room to spare. This was a little frightening at first because it was abandoned (or so we thought) and so we thought that something was living in it and coming back! But after awhile we realized that nothing was living there ( we still didn't climb down into it though) so we weren't afraid.
This was a really cool sight!!
