For anyone who might be interested, charts for Rothera, where the Twin Otters will be heading as soon as weather permits, from Punta Arenas (in Chile, Matelo, not Peru....)

The GNSS approach is new since I was last there, (2009).
The normal flying season starts in early October and runs to early March. I did two winter flights into Rothera, in the Dash 7, one after a fatality on the base, and the other for a person with a collapsed lung. Both were in August, when there were a few hours of daylight each day, but on the first one, we were lucky to get in, as the weather deteriorated significantly after we had passed PNR and we landed with about 2000m in blowing snow.
The 2013 KBA accident happened in the transantarctic mountains, which go up to almost 15,000'. The normal route between Rothera and Pole threads its way between King George Island and the peninsula, and then over fairly featureless plateau for most of the rest of the route.
Ref. the iceberg accident at Rothera in 1994 - that is a persistent hazard at Rothera, the deep water at both ends of the runway allows bergs to float past very close. When the sea is not frozen, they tend to move on fairly quickly, but some winters they can get caught in place, and make for some interesting approaches.
(Just noticed, the aerial photo of the runway on page 8 of the approach info linked above, shows a good example, with a couple of icebergs frozen into the sea on short final to RW 18)
