Whale's Mouth

A large, wide hole in the rock is filled with hot, blue water, resembling a large mouth.
 

This hot spring was named by a park naturalist in 1967 because its shape "resembles the mouth and gullet of a giant fish". This is regarded by many as an especially peculiar thing for a naturalist to say, due to the fact that whales are not fish.
