This is from Palouse Falls State Park. It was formed only 15,000 years ago by the great Missoula floods. Can you imagine a 1,000 feet tall body of water cutting this vast canyon? This is what Geologist's have concluded.
This is also at the Palouse Falls State Park. The waterfall is nearly 200 feet high.
This sign cracked me up. Note the "CAN". I would have to say that "Falling WILL be deadly"
