Northwestern Wyoming

A boardwalk follows the lakeshore, providing close access to the lakeshore's geysers.

This is Fishing Cone.

"Mountain men told of a geyser on the shore of a high alpine lake where one could catch a trout, swing the pole around, dip it into the boiling pool, and cook the fish without taking it off the line."

"This cooking-on-the-hook feat at Fishing Cone became famous after it was described by a member of the 1870 Washburn Expedition. Visitors often dressed in a cook's hat and apron to have their pictures taken at the 'Chowder Pot' or the 'Fish Pot'. Anglers often injured themselves while straddling the boiling water, and their feet damaged the geyser's cone. Fishing is no longer allowed from Fishing Cone."

"Visitors are sometimes surprised to find Fishing Cone underwater. During the spring and early summer the lake levels rise from melting snow and cover the vent. When exposed, the temperature of the cone's water averages just above boiling."

Big Cone.

"Not long ago, Black Pool really was black. Lower water temperature allowed thick mats of dark green and brown thermophiles (heat-loving micro-organisms) to grow in the pool, causing it to appear black. The water temperature rose during the summer of 1991, killing these organisms. Black Pool also erupted that summer and several times the following winter. Like Abyss Pool, Black Pool is now a quiet and beautiful pool."
