Tucker Sno-Cat

E.M. Tucker started putting together his thoughts on traveling through harsh snow conditions in 1942.  Over the past seventy years the original design has mostly been retained but the improvements have made it the premier method of getting around on vast fields of snow.

The original Sno-Cat had 10hp and drove only the rear tracks.  Today's versions are powered by Cummins diesel engines that range from 160 to 300 horsepower. A fifty gallon fuel tank and a 36,000 BTU heater provide both extended range and reasonable comfort for the occupants.

And, yes, the pictured Sno-Cat was saved from falling into the crevasse.
