color video of the Antarctic Snow Cruiser at Westfield, New York 1939

this you tube channel https://www.youtube.com/@beachnutbeachball/videos has a lot of amazing color videos from before color video was normal, especially of trains

the giant snow cruiser built for the Admiral Byrd Antarctic expedition, Chicago 1939. 55 feet long and 15 feet high

It was abandoned in 1940

During Operation Highjump in late 1946, an expedition team found the vehicle and discovered it needed only air in the tires and some servicing to make it operational. 

In 1958, an international expedition uncovered the snow cruiser at Little America III using a bulldozer. It was covered by 23 feet of snow and a long bamboo pole marked its position.

click the "Snow Cruiser" link tab under this post to see the earlier complete coverage I've done on this unique vehicle that went to Antarctica

I wonder what ever became of the Chicago Military Vehicle Research Institute and the Research Foundation of Armour Institute of Technology?

These are both names of the place that made the Snow Cruiser project happen.

There were some mighty big Goodyears on Admiral Byrd’s Antarctic Snow Cruiser in 1939

Admiral Byrd’s Antarctic Snow Cruiser was built in 1939 to support his third Antarctic expedition, and built by the Pullman Company of sleeping car fame at a cost of $150,000.

Unfortunately, the Snow Cruiser proved much slower in the field then her specified cruising speed of 10-13 miles per hour. Though she may have been adept at fording crevasses, she was unable to climb the 35 percent grade she was designed for, due to it's 30-ton weight.

Byrd’s Snow Cruiser proved so problematic that it only managed to cover 96 miles in 12 months of activity and much of that in reverse!

As a result, when the expedition ended the vehicle was abandoned. She was rediscovered sometime in the 1950s only to float away on an ice shelf and sink to the bottom of the sea. 

I posted about this 8 years ago, http://justacarguy.blogspot.com/2010/12/antarctic-sno-cruiser-was-driven-to.html  and this is the first time new photos have popped up online since then that I've come across. Back in 2010 I posted the very few I could find, some were even in color, and that video is pretty cool too, but that was all there were online at the time, and luckily, as the years go by more and more photos are scanned and uploaded
