🔗 Antarctic Snow Cruiser

The Antarctic Snow Cruiser was a vehicle designed from 1937 to 1939 under the direction of Thomas Poulter, intended to facilitate transport in Antarctica during the United States Antarctic Service Expedition (1939–41). The Snow Cruiser was also known as "The Penguin," "Penguin 1" or "Turtle" in some published material.

Poulter had been second in command of Byrd's Second Antarctic Expedition, launched in 1934. From his time in the Antarctic, Poulter had devised several innovative features. However, the massive Snow Cruiser generally failed to operate as hoped under the difficult conditions, and was eventually abandoned in Antarctica. Rediscovered under a deep layer of snow in 1958, it later disappeared again due to shifting ice conditions.
