Olympic National Park - Crescent Lake
Lake Crescent, in the Olympic National Park, was formed when glaciers carved out deep valleys during the last ice age. About seven or eight thousand years ago a landslide dammed the outlet and the valley filled with water forming the lake. A new outlet eventually was created, but anadromous fish that had entered the lake prior to the landslide were now unable to negotiate the new waterway. Two distinct species of trout have subsequently evolved and now inhabit the lake - Beardslee and Crescenti Cutthroat.
Efforts have been made to ascertain the depth of the lake. Officially it is listed as being 624 feet deep, but is suspected of being much deeper. At a depth of 624 feet it is ranked as the second deepest lake in the state, but many believe that it is over one thousand feet deep and thus the deepest.
The water is remarkably clear due to a lack of nitrogen which fosters the growth of algae.
