About the event

The White Rock quarry was opened in the 1870s as a producer of white lime for the manufacture of mortar and whitewash, and 

was for a time one of the largest lime producers in the country. 

Current commercial quarrying operations produce armor stone, rip rap and aggregate entirely from the Lockport Dolomite. Although the dolostone is generally of very high purity, some areas are rich in vugs and veins that are mineralized with fine specimens of brown fluorite, white to colorless celestine crystals, calcite, sphalerite and occasional galena. Similar specimens are found in many other quarries in the region, but the White Rock quarry at Clay Center has become the most famous by far because of the sheer number of fine specimens it has produced in comparison with the other localities.

Speaker Jamison Brizendine provides a pictorial overview of history and minerals.

Guests are welcome at our meetings. 

The program is fit for every age.
