Lexington LimestoneThese outcrops of rock are road cuts through the Lexington Limestone, near Lexington, Kentucky. It is Ordovician in age, deposited just under 500 million years ago. The Cambrian to Ordovician was a time of high sea levels, and ocean waters flooded part of what is today North America behind the Taconic Mountain range.Much of central Kentucky sits atop these limestones. Water flowing through these limestones picks up calcium and has its pH fixed by the rocks; this water forms the basis for bourbon distilleries in that state. The high calcium also permeates the soil and helps contribute to strong bones in horses; these rocks therefore contribute to two of the major industries in that state.-JBBImage credits:https://flic.kr/p/25s8mCbhttps://flic.kr/p/Jq4uGbhttps://flic.kr/p/26u32x5References:https://bit.ly/2HyDXz1https://igws.indiana.edu/compendium/comp2pes.cfm -- source link
