About This Waterfall

Big Blowout Falls is the middle of at least three known waterfalls along the east branch of Big Blowout Creek. The falls consist of three distinct drops, only two of which can be seen together while the third must be viewed separately. The uppermost tier plunges a nearly sheer 48 feet, followed shortly by a second sliding drop of 19 feet. The creek then makes a gradual twist to the right, at which point it plunges then cascades over the third tier of the falls, which first plunges over a stout free-falling step and then cascades down a rough exposure of bedrock, splitting into two distinct channels in the process. Big Blowout Creek above this waterfall drains from a basin which only covers about 0.4 square miles in area. The stream retains a modest flow during the winter months, and can actually swell to a significant enough volume that spray ejected from the falls can present a problem for photography, but by the summer months its volume should be reduced to just a trickle. During drought years it may dry out entirely by September.Like the other waterfalls in the immediate area, we know of no official name of this entry. We chose to title it after its stream because it not only personifies the name of the creek with its forceful plunge, but because it is also the most boisterous and audibly significant of the several waterfalls in the immediate vicinity.
