Pikeview Quarry Founded

Pikeview Quarry is founded in Colorado Springs, Colorado. Between 1903 and 2018, limestone was excavated from the quarry via the drill and blast mining method. Prized for its contribution to concrete’s strength and reduction in shrinkage and cracking, limestone was a sought-after building material.

Pikeview Quarry Expansion

In 1940, the quarry was expanded to provide limestone for the construction of the United States Air Force Academy.

Pikeview Quarry Ownership Transition

After changing ownership several times, the quarry was finally acquired by Castle Concrete (now Castle Aggregates) in 1972.

Pikeview Quarry Contributions

Limestone mining continued through 2018. It is estimated that more than half of the limestone used to build Colorado Springs was sourced from Pikeview Quarry.

Pikeview Quarry Permanently Closed

Following a series of slope failures, all Pikeview Quarry mining operations were permanently halted in 2018.
