When we first went in, the weather was quite nice outside, but, after being underground and wearing my sweatshirt, coming up out of the hole, found the outside temps as being a bit warm. Ron wanted to walk down towards the natural entrance to maybe get some pictures of it, but, I didn't really want to walk in the heat. Instead, we browsed around the gift shop and bought an ice cream in the restaurant. We just took a picture of the path to the entrance and also the buildings you see on the side of the hill probably belong to all the rangers working at the park.
