The Blackfeet seized Colter and stripped him naked, then discussed methods of torturing him to death. They decided to set him up for a target, but the chief interfered--that was not exciting enough for him. Seizing Colter by the shoulder, he asked him if he could run fast. The question was greeted with howls of delight by the Blackfeet. The chief led Colter out on the prairie about three hundred yards from the band, pointed in the direction of the Jefferson River, told him to save himself if he could, and cast him loose. Colter ran, the Blackfeet whooped and pursued, and the race for life was on. The ground was thick with prickly pears that pierced Colter's bare feet. Nevertheless, he kept ahead of his pursuers. When about half the five miles to the Jefferson had been covered, he ventured to look back. The Indians were much scattered, and he had gained on the main body; but one Indian, carrying a spear, was close upon him. Colter exerted himself to the utmost, and by the time he came within a mile of the Jefferson he was exhausted and blood from his nostrils had covered the front of his body. He stopped suddenly, turned, and spread out his arms. The Blackfoot, almost upon him, but also exhausted, attempted to stop and throw his spear, but he fell and the spear broke. Colter sprang upon him, seized the spear-head, pinned him to the ground, and ran on. The foremost of the remaining Indians stopped by the fallen runner. When others came, they all set up a whoop and resumed the chase. Colter gained the river-bank in advance of all his pursuers, just where there happened to be a large beaver house, standing partly against the bank and partly in the water. Knowing that the entrance to the house was at the bottom, under the water, he dived and succeeded in forcing his way to the floor just above the water-level. Man fleeing from man has hidden in strange places, but it may be doubted whether one ever before sought safety in a beaver house of brush and mud! Soon the Blackfeet were searching all over the place, "screeching like so many devils." They made search for the naked white man all the rest of the day. Apparently even their savage cunning never suspected the beaver house. Although they frequently clambered over it, they did not disturb it. When night came and Colter could no longer hear the Indians, he swam downstream, gained the prairie, and headed for Fort Manuel, some two hundred miles away. Naked, with bleeding feet, he walked over prickly pears on the prairie and through snow in the mountains, which he crossed above the timber-line. The sun blistered him. Part of the time, he traveled by night and lay hid by day. He appears to have lived chiefly on the Indian-turnip (_Psoralea esculenta_). Colter arrived at Fort Manuel in terrible shape. At first the men did not recognize him. He had been eleven days in making the distance between Three Forks and the fort.
