A 1920 article in The Coal Industry described Kinlock as "a plant which is built entirely of steel and concrete and located on the Allegheny Valley division of the Pennsylvania railroad, that has been designed to remove coal at a depth of 148 feet from the surface, the slope type of opening being used. The seam of coal that is mined is made up of the upper and lower Freeport veins, and is about 7 feet thick, the two veins being separated by a layer of bone which is removed by hand picking both in the mine and at the picking tables ... The Valley Camp Coal Company has built a town of attractive appearance for the benefit of the miners and their families. The houses are all of the double-frame type and are rented to the men at very reasonable prices. They are all supplied with running water from a spring and every precaution is taken to conserve the health of the community. The town is located within 400 yards of the township school where the children receive competent instruction. This school has been equipped with a large playground and the necessary equipment at the expense of the company. The mine has one of the best baseball teams in the valley, and a playground and picnic grove is located in a pretty valley at the rear of the company store."
