U.S. Navy SEAL candidates wade out of the Buskin River after spending five minutes in the near freezing water during a re-warming exercise in Kodiak Alaska, April 8, 2009. Candidates completed the re-warming exercise after spending 48 hours in the Alaskan mountains learning how to navigate through the rugged terrain and survive the frigid conditions. The 28-day cold-weather training course taught in Kodiak is part of a yearlong process to become a U.S. Navy SEAL. U.S. Navy Photo by Petty Officer 2nd Class Erika N. Manzano
