Description

Sky Pond is drained by a perennial stream (Icy Brook). It is oligotrophic and dilute, occupying a cirque formed during advances and retreats of the Taylor Glacier. Sky Pond is classified as an alpine lake on the basis of its elevation. It is typical of other alpine lakes in Colorado in that it has a rock-and-gravel watershed and year-round snowfields in the watershed. It does not become thermally stratified during spring and summer (April through October). This lake is visited frequently by hikers during the summer.
