Locations: Tramway Quarry.

Tramway Quarry

The Tramway Quarry mined basalt.

The quarry was somewhat troublesome to properties below. On May 4, 1907 Cracks opened in the ground below, and the ground seemed to be moving. A huge mass ploughed down the ountain below the quarry. In September of the same year, A 12- by 12- by 12-foot boulder fell from the quarry and lodged in the Church Ditch just above a house.

Again, in 1914 a few thousand tons of rock slumped several yards and covered up the access road at the Tramway Quarry. Mountain. Heavy snow and rain have softened the "clay and ash." The ditch company and the railroad experienced much trouble in previous years when great sections of hillside moved slowly down toward Clear Creek.

Valley of Clear Creek opens onto the plains; Denver in right distance.

Although rock was quarried for the Denver Tramway, there was indeed an aerial tranway over the Farmer's Highline canal to a crusher at Rockdale. A deed for the right-of-way was filed with the county clerk in 1915.
