Remember the Franklin No. 7 mine was located about 900 feet east of the public boat launch at Lake 12. The approximate location of the Franklin No. 7 mine is 28101 S.E. Green River Gorge Road. This is about 1.5 miles from the center of the Franklin townsite. The building with steam was the power plant, witness the smoke stacks coming from it. It was served by the Bruce Branch of the Columbia & Puget Sound Railroad, which paralleled the Green River Gorge Road and ended just south of Lake Twelve. The mine opened in 1893. It was sunk 3,185 feet along a slope with a 30° pitch, with coal extracted from eight underground levels. It reached a depth of 1,046 feet, or about 150 feet below sea level. The mine produced coal until 1907 when it was shut down and the rails taken up. During the early years of World War II, the mine was re-opened by Pacific Coast Coal Co. and later operated by the Strain Coal Co.
