I've been doing a little itinerary research and came across this essay about Wrangel island - beautiful photos.

I tried to create a simple google map of where we are going to visualize what might have changed - the red are the eliminated stops, the green are the added. Chetyrekhstolbovoy Island (aka Stolbovoy Island) is west of some of the planned destinations (Dmitriy Lapov Strait, Lyakhovsky Island) so not sure why that part changed, but maybe the De Long Islands are too far north. I can't really interpret Marc's ice charts.

I'm guessing that Pevek is the new refueling spot, but I can't imagine what we will do for two days there. Hopefully explore nearby.
