This 27 panel, 309 megapixel Nordenskjöld Glacier nearly killed my computer in processing it, and I had to give up my usual non-destructive workflow of Smart Objects. I resized to 100 megapixels before uploading it to Google+, so if you click through you can zoom and pan on the 100mp version.
The gigantic glacier flows into the head of the Cumberland East Bay on the northern side of South Georgia. This was from the third full day in South Georgia and after some Zodiac cruises in Ocean Harbour, we made our way around to this side cruising across the bay, eventually ending up at Grytviken. The day started off with some sun but it became overcast quickly with occasional rain.
Wikipedia has a neat overlay of on Google Maps of the area with interesting information on the various bays and points of historic interest, definitely worth checking out.
