100 years since the Eastland -- Chicago Tribune. The SS Eastland rests on its side in 20 feet of water after slowly rolling over July 24, 1915. The Tribune wrote, "Close to the Eastland's berth the river is only a little more than twenty feet in depth. The big excursion boat, with a beam of more than twice twenty feet, went no further when its port side found the bottom. It lay like a toy boat of tin wrecked in a gutter, its starboard half rising clear of the water."
