The Clark and McCormack Quarry and House consists of a historic quarry and the adjacent residential estate of one of the owners in Rockville, Minnesota, United States. The Clark and McCormack Quarry was established in 1907, and was the source of Rockville Pink granite. The John Clark House was built in 1924 with granite from the quarry. The property was listed on the National Register of Historic Places in 1980 for its local significance in the theme of industry. It was nominated for being one of Minnesota's major producers of structural granite and the best representative of eastern Stearns County's important granite quarrying industry. Description The site of the Clark and McCormack Quarry was originally a dome of granite rising above the surrounding land. Once the exposed rock was removed, quarrying continued below ground, leaving the pit that is visible today. The granite is coarsely but evenly grained, with unusually large feldspar crystals that give the stone a glittering, pinkish-grey finish when polished. The deposit is also unusually uniform in its color and texture, with widely spaced joints that allowed for the cutting of massive blocks. The Clark and McCormack has an exceptionally small waste heap compared to most other quarries because so much of its stone was usable. In the early 20th century, handcarts on tracks were used to transport rough blocks to shops on the periphery of the quarry for finishing. No historic buildings or structures remain around the quarry itself. The operation's early buildings were all demolished as the pit was enlarged, and a few cutting sheds that survived longer were lost to a fire. To the south, however, across Minnesota State Highway 23, stands the John Clark House. It is a two-story rectangular building with a single-story sunporch on one side. The entrance is centered on the wider, west-facing façade. The house has a hip roof with chimneys at either end. The walls are built of rusticated granite from the quarry. The property includes a detached three-stall garage at its southwest corner. Its design closely matches the house, with stone walls, a hip roof, and its own chimney. History John Clark was a Scottish immigrant who worked as a stonecutter in his home country, then in Youngstown, Ohio; Detroit; and Stratford, Ontario, before settling in Saint Paul, Minnesota. He joined the firm of Matthew Breen, which had opened the state's first commercial quarry in 1868. Clark
