We were only out for about 4-5 hours, without any major incidents, apart from a lesson on the importance of stowing our gear and clothes properly when we aren't using them. Mother Nature threw a lot at us during that time. It started drizzling half way through our hike out to the beach, rained pretty hard while we were there, with the wind kicking up was well. The rain subsided slightly when we left the beach and then it started to snow on our way out.

Interestingly, the wikkiup we built this past summer was still there! Someone had obviously used it since we were there last. They removed the bench in favour to two stump stools and also built a nice wind block in front, with enough room to build a long fire between and the wikki. We added some more support to both it and the wikki, threw up one of the heat sheets to stop the rain from getting in on one side of the wikki, built a nice fire outside the entrance and had a great lunch. (Would have hung a mylar blanket inside if it was any colder or windier, to reflect the heat from the fire.

Kind of like the hunters who left you the chopped wood, we left a large tin can inside, as well as a nice pile of driftwood for the next fire.
