Fishing Cone is a geyser in the West Thumb Geyser Basin of Yellowstone National Park in the United States. The name Fishing Cone can be traced back to tales told by mountain men of a lake where you could catch a fish then immediately dunk it into hot spring and cook it on the hook. It is no longer allowed to cook fish in the geyser. The increase in the lake level has changed this geyser and it no longer erupts.
