CHAT (CHAT HAULING)
The term "chat" is applied to fragments of siliceous rock, limestone, and dolomite waste rejected in the lead-zinc milling operations that accompanied lead-zinc mining in Ottawa County, largely in the first half of the twentieth century. These chats, found as huge man-made mounds in that county, are utilized as construction aggregate, principally for railroad ballast, highway construction, and concrete production.
