Big Auger
Big Auger is a sentient river from Lumberjack folklore. It had a rocky riverbed and moved like a corkscrew with a twisting motion. It makes gurgling sounds and can jump and move around. It could rotate so fast that it caused the water to boil. It challenged Paul Bunyan and fired ninety-nine barrels worth of water into his eyes. In response, it got slapped by the acre large hand of Paul Bunyan, who followed up by slamming a mountain into Big Auger to dam it up. Big Auger became calm for a while but eventually bored through the mountain and went wild again. Paul Bunyan tried strangling after this and it boiled away the corkscrew to its bed making it a peaceful river. This fight formed what is now Niagara Falls, named after Paul Bunyan’s former dog.
