6) Caption reads:  Crossing the Whirlpool at Niagara Falls, Ontario, may be made in the Spanish Aero Car, which runs on a cable high above the waters of the Whirlpool. To the west, there is an ancient gorge, which is filled with gravel, silt and quicksand to a depth of over 240 feet. After unsuccessful drilling to this depth, bits of wood came to the surface which proved to be a subarctic type of spruce, and a radioactive carbon test dates this as 14,000 years old.
