Name of Waterfall

Upper Green Lake Falls

Description

Almost immediately upon exiting the almost unbelievably blue waters of Green Lake, the unnamed branch of Bacon Creek which originates in the Green Lake Glacier plunges over a 91 foot tall set of falls where it begins its tumultuous descent into the upper Bacon Creek valley. Green Lake features two distinct outlet streams, separated by a large bulbous granite outcrop, which run parallel to one another for about 500 feet, at which point they drop over the first cliff band below the lake. The southern and larger of the two outlets veils out over a fan-shaped fall, while the northern outlet plunges in a much narrower stream into a pile of large boulders. The two channels converge shortly after and continue running down a bedrock trough towards the top of Green Lake Falls about one-quarter of a mile further downstream.
Generally lakes which feature dual outlets will see the smaller of the two run dry at some point in the year as the flow of water entering the lake subsides with the winter snowpack. With Green Lake this appears to not be the case, as the Green Lake Glacier provides an ample inflow to the lake and ensures that a fairly consistent volume of water flows from each outlet (given the volume of both outlets will be significantly higher in May and June than in September or October).
