The McMurdo grid offers simulations designed to help individuals and teams learn about how to face severe difficulties and work together to go beyond what is imagined as possible. Visitors arrive at the grid on the Windsong yacht docked offshore of Ross Island in Antarctica. McMurdo is built on the bare volcanic rock of Hut Point Peninsula on Ross Island, the solid ground farthest south that is accessible by ship. Excursions from the ship to the island starts with arrival at the McMurdo station. The McMurdo grid places emphasis on research conducted by the National Science Foundation in Antarctica. Visitors can participate in a Weddell seal health checkup activity to learn about research examining the impact of climate change. The grid also offers an Expedition Club to learn about the famous Ernest Shackleton expedition and how against all odds every crew member of the Endurance survived losing their ship, months of isolation and hunger in the Antarctic, before being rescued off of Elephant Island. The second simulation takes place on Elephant Island and involves participants working in teams to determine courses of action for avoiding hazards. And finally, the third simulation takes place on the grid at a DC-3 crash site whereby participants must locate, prioritize, and offer rationales for use of crash items necessary for survival. Based on simulation play feedback is offered to each player regarding their odds for survival. The genesis of this activity comes from training offered for Special Operations teams.
