Has anyone floated Butte Creek? Access is South of the Denali highway 2 or 3 miles to Butte Lake. The creek drains south from the lake and makes a big "U" before flowing into the big Su just downstream from the bridge. Looks like it would be 35 miles or so from Butte Lake to a take out spot on an ATV trail just before the creek flows into the Su. Considering doing this in a packraft, any info would be great
