more reconnaissance

Today we explored another area where Kronebreen enters the ocean that has opened up since 2005. We talked a bit about the glacial features that a glacier leaves behind when it retreats from an area, and the significance of those features - we also looked at other features like the ones below:

Which way is the rock dipping? Clearly an ice axe and rifle are needed to figure this one out, rather than a brunton.

the scale of the landscape is unbelievable, so here are some people for scale

On the way home, we found a large ice berg that had calved off from the base of the glacier. Ice bergs make it relatively "easy" to get a sample of the basal till and an idea of the amount of sediment that the glacier is carrying.

Someone, who will remain nameless, told me that I have not provided enough photos of us in our survival suits. More of those are bound to come once we start studying the sedimentation processes, but here are a few shots for the moment:

survival suits and matching dry bags 

driving lessons (avoid the bergs)
