Double Boof was named for the two sweet 6-foot boofs right after each other that used to exist. However, high water rearranged this rapid to where the first boof lands on a heinous-looking rock and the second boof rock is totally dry. The line now is to cut to the right in front of the first boof rock and launch a SIKy off a rock on right bank. From here, ferry out to the left under a wild spray of water coming off the heinous rock and down over a small drop. This leads right into a really cool slide run down the middle.
Several more slides and rocky drops carry you for the last 1/8 of a mile to the Blackwater. After having survived a killer run on the North Fork, you have two options : brave a high water run on the Lower B or carry up and do the North Fork again!
