This blast channel was created in an effort to save logs from being damaged by the near-by 'crooked chute'. It's funny - the crooked chute is so insane even loggers didn’t want to risk sending logs down it (so they blasted the channel) but the brave of the brave white-water enthusiasts will take on crooked chute and make it look like a mere swift. I've seen this rapid in both high and low water and both cases I consider running it slightly insane!
