In the early days of mining there were a cluster of collieries in the Locust Gap operated by individuals under the same name prefixed by "locust". these collieries were "The Locust Gap Colliery" at the northern end of the gap, "The Locust Summit Colliery" directly opposite the Locust Gap Colliery, "the locust spring colliery" midway in the gap, "Locust Gap(new) Colliery" midway in the gap, "Wolf Colliery" midway in the gap and "Locust Spring Colliery" at the southern end of the gap.
Located on the east side of the Locust Creek and was opened by a drift driven east on the north dip mammoth veins by Hass and Fegley in 1855.
The first shipment of 13,287 tons was made in 1856.
They mined the drift only a short time when they sold the colliery to Seascholtz, Fegley & Co. in 1856 who operated it to 1864 when they failed.In 1864, the Mammoth Vein Consolidated Coal Co. mined the drift to about 1866 when the workings had been extended 3500 ft. to the land line. This company retired from the mining business and was succeeded by Graber & Kembel who mined the remaining coal to 1871 when the breaker was destroyed by fire and the colliery abandoned.
Located in the Locust Gap on the west side of Locust Creek. The colliery was opened by a water level tunnel driven north 280 ft. to the south dip mammoth vein by Kase Reed and Co. in 1855. The first shipment of 14,265 tons was made in 1856. Kase Reed & Co. drove the gangway eastward for a short time when they were succeeded by Zimmerman and Purcell who purchased the colliery in 1856. They continued the mining to 1858 when they failed.
In 1859, W. F. Deward came into possession of the colliery and A. S. Wolf & Co. leased and operated it to 1864.
In 1864, the Mammoth Vein Consolidated Coal Co. purchased the colliery and operated it to 1868 when the company went of business.
In 1868, Graber, Kembel & Co. leased the colliery and in 1869 they sunk the slope 280 ft. on the same vein to a local basin and drove several gangways in different directions, mining the basin coal to exhaustion in 1873 and the colliery was abandoned on 1875.
The colliery was connected with the Monitor Colliery and the drainage was raised to the surface at the wolf slope.
The total shipment from Wolf Colliery was 320,639 tons.
