Famed long-distance swimmer, Bert Thomas, a 275-pound ex-Marine frogman who conquered the Strait of Juan de Fuca, checks the January, 1956, temperature of Puget Sound. Dick Beckman and Betty Jane McGuigan hold a thermometer sign registering 45 degrees. On the night of January 26th, Thomas attempted the first long-distance, cold water, midwinter endurance swim in history and the first 18 nautical mile swim between Seattle and Tacoma. After 1 hour and 20 minutes in the water, Thomas ended his swim due to frigid winds and 42 degree choppy waters.
