As we made our first anchorage, our guide encouraged us to get our ski gear together quickly for a late afternoon ascent of Banco Island, and our first, warm-up ski in Antarctica. I looked up at the intended route and thought to myself, this is going to be some challenge. I had joined a four week expedition with the yacht Spirit of Sydney, from Ushuaia, Argentina to the Antarctic Peninsula, for the sailing, kayaking and skiing adventure of a lifetime.
