Brief Description: The Bill Skelton ranch was hit by two tornadoes. Damage was extensive. A barn roof made from 8 to 12 inch logs was carried away. A two foot in diameter cottonwood tree was snapped five feet above the ground. A 24-foot horse trailer was picked up and carried 65 yards landing on its top and it hit and damaged a tractor enroute. A 1.5 ton truck was tipped over and an out building made from heavy beams and spiked down was twisted and moved. A mobile home was lifted and a large fuel tank was deposited under it. Several one ton hay bales were moved 20-30 yards. Golf ball-sized hail fell ahead of the tornadoes and covered the ground to a depth of five inches. | |||||||||||
