Tham Krasae, a small cave in Kanchanaburi Province (fig.), has a number of remarkable natural rock formations.

Included are several rocks that resemble animals, such as a sphinx-like figure, shown in the picture above, and a large seated frog, seen in the photo here on the right.

And this rock, which is found on the floor near the entrance of this Buddhist cave, is reminiscent of a giant tortoise.
