Introduction to the Tengu Watching Moon Stone: There are two huge stones on the ridge in the west of Whirlwind Mountain, with sharp edges and corners overlapping each other. The upper square stone is shaped like a dog's head, and the lower feldspar is shaped like a dog's body. Viewed from a distance, it looks like a dog squatting, looking up to the southeast, and looking up at the moon, hence the name "Tengu Watching the Moon."
