Admiral Byrd’s Snow Cruiser.
Sometime in the 60s, a naval ship happened to notice a big chunk of ice broken off the Ross Ice Shelf, which exposed a buried Little America exploration station abandoned since the beginning of WW2.
The Snow Cruiser was parked nearby, and also buried by snow and ice.
I’m 99% sure the cruiser sand to the bottom of the sea when the iceberg melted, but there is the possibility the Soviets recovered the vehicle, and used it as a basis for their antarctic vehicles…
…The Kharkovchankas.
