Time to test the dead sled on open tundra. It wasn't too bad, but didn't help that it was uphill and there was a lot of deadfall in the spruce on the way back to the road. I caught a root somewhere and tore a big hole in the front of the sled, but luckily the part that is up off the ground, so it didn't ruin the sled. Had to burn off some of those calories from all the chips I was snacking on during the drive.
From this last picture, you can see the ledge that the caribou was working up and down. I shot him on the far left of the picture next to those 5 gangly looking black spruce trees.
