Name of Waterfall

Unnamed Waterfall

Description

The unnamed branch of Straight Creek which originates in Blue Lake on the Dark Divide produces a series of significant waterfalls as it tumbles down into the valley to join with Straight Creek proper. At least four significant falls occur on the stream below where its two branches - one originating in Blue Lake, and the other in the basin to the northeast - merge, with at least one additional fall on either branch upstream from the confluence as well. The final fall in the series is a sliding cascade type fall located about 500 feet upstream from the confluence with Straight Creek. The falls drop 36 feet in a run of approximately 100 feet, with an average width of about 15 feet.
The stream producing this waterfall drains from an area covering approximately one square mile, which includes 13-acre Blue Lake. The basin rises to an elevation of over 5000 feet at its extreme, and as such will receive fairly heavy winter snowfall. During the spring and early summer months the volume of this stream will be healthy due to ample runoff, however its volume is expected to dwindle considerably by the end of August, and potentially become just a trickle by mid to late September without replenishing precipitation.
