Limestone in Wyoming / Montana

[jlane]

"The slab broke up as it traveled; now, more than 100 huge limestone blocks are scattered across some 1,310 square miles (3,400 square kilometers) of younger rocks in northwestern Wyoming and southeastern Montana."

Sounds a little spread out but curious if anyone has ever seen / climbed on one of these blocs. If anything the science (yo!) behind the landslide is somewhat interesting.
