Six Mile Creek is a short, approximately 10 miles (16 km) waterway with some of the most exciting whitewater rafting in Alaska. The Six Mile Creek drainage starts as Bertha Creek flowing from the top of Turnagain Pass on the Seward Highway, part of the National Scenic Highway Program. Bertha Creek and Granite Creek join to become The East Fork of Six Mile Creek and at the confluence with Canyon Creek become Six Mile Creek which flows about eight miles to where it empties into Turnagain Arm shortly after flowing past the small community of Sunrise along the Hope Highway.
