I could use help remembering the story behind this bridge building
exercise. From the full set of photos, not just the edited ones here,
I think it was on the hike to Lake of the Hanging Glacier. Since I am
photographing from the other side, it must have been possible to cross
without the bridge, but the bridge made it easier/safer.
