In the spring of 1990, Tim Macartney-Snape decided to climb Everest from "sea to summit". First, Tim had a swim in the tepid waters of India's Bay of Bengal then set off on foot across the Gangetic plain toward the distant Himalayan foothills. Four months later, after climbing alone from Base Camp and without the assistance of oxygen, he set foot once again on the highest point on earth. Tim's solo ascent of Mt. Everest was named the "Sea to Summit" expedition.
