The Snow Cruiser arrived at Little America in the Bay of Whales, Antarctica with United States Antarctic Service Expedition in early January 1940 and experienced many problems. It was necessary to construct a ramp from timber to unload the vehicle. As the vehicle was unloaded from the ship, one of the wheels broke though the ramp. The crew cheered when Poulter powered the vehicle free from the ramp but the cheers fell silent when the vehicle failed to move through the snow and ice. The large, smooth, tread-less tires were originally designed for a large swamp vehicle; they spun freely and provided very little forward movement, sinking as much a 3 feet (0.91 m) into the snow. The crew attached the two spare tires to the front wheels of the vehicle and installed chains on the rear wheels, but were unable to overcome the lack of traction. The crew later found that the tires produced more traction when driven backwards. The longest trek was 92 miles (148 km) ? driven completely in reverse. On January 24, 1940, Poulter returned to the US, leaving F. Alton Wade in charge of a partial crew. The scientists conducted seismologic experiments, cosmic-ray measurements, and ice core sampling while living in the snow- and timber-covered Snow Cruiser. Funding for the project was canceled as the focus in the United States became World War II.
