Very well and professionally conducted trip ! the only thing that can spoil your trip is the weather ..yes, the fog. Safety is no.1.
Take note not to move to fast on the ice after u remove your crampons and take care of your camera gears if you shooting the descending helicopter. The rotor wash can send your sunglasses, light cameras etc...flying into the water holes.
Remember to listen to listen to instruction from the experienced guides... and you will have the trip of a lifetime.
