A rainbow glows against the dark grey sky, in a brief interlude between squalls and hailstorms. We held tight to our packrafts to keep them from blowing away in the stiff wind, as we walked towards the crossing of Alsek River at Dry Bay. Dry Bay marks the northern edge of Glacier Bay National Preserve, but is still deep in the wilderness. It would be another 50 miles before we reached the nearest town of Yakutat. And that was just halfway on our 4000-mile journey - by foot, ski, and packraft. For more information on our journey visit: http://www.GroundTruthTrekking.org Photographer: Erin McKittrick
