In which Michigan region are the majority of limestone quarries located?

The majority of limestone quarries in Michigan are indeed concentrated in the Northern Lower Peninsula region. This area is rich in mineral resources, including limestone, which is a significant product used in construction, agriculture, and various industrial processes. The geology of this region, characterized by sedimentary rock formations, has led to numerous quarries that exploit these valuable deposits.

While limestone can also be found in other areas of Michigan, such as the Upper Peninsula and parts of the Southern Lower Peninsula, the Northern Lower Peninsula holds the largest concentration of operational quarries due to its geological makeup and the historical development of the mining industry in that area. The Saginaw Valley, known for other types of mineral resources, does not host the same quantity of limestone quarries as the Northern Lower Peninsula, making it less significant in this regard.
