Two viewpoints-one looks at problems, the other at benefits. Who's right? Maybe both-as far as they go. There's no denying it. Mining rock for crushing, agricultural limestone, sand and gravel, and stone quarrying can create esthe "A quarrycan be tic problems. The land is usually disturbed. The operation is some an awful meSS.' times noisy, dirty. Transportation, most frequently by truck, can cause blowing dust, increased traffic loads. But at the same time, it's hard to deny the importance of rock prod ucts. Agricultural limestone low ers soil acidity, improving crop production. Sand and gravel or crushed rock are inexpensive building materials for concrete foundations, walkways, drives. Sand fill is a stabilizing construc tion base. Other stone products make decorative exterior trim and landscaping. All told, there are few practical, low cost substi tutes for locally produced stone products. What do we do in a situation like this? Eliminate environmental ob jections by doing without stone products? It's a tough question, made tougher when you consider transportation costs. Carrying these materials any distance in creases cost dramatically. It's best to mine as close as possible to where they will be used. And that's made possible with recla mation programs that can convert worked out quarries, aggregate pits into productive and attractive projects: parks, lakes, residential and industrial sites. This multiple land use concept works to give us both mines and useable land. We at Caterpillar make ma chines that both dig aggregate pits and develop land for other useful purposes. We feel multiple land use can benefit a growing community economically and environmentally. There are no simple solutions. Only intelligent choices. a CATaT CLA Caterpillar, Cat and 0 are Trademarks of Caterpillar Tractor Co. "Stone mining means building-progress'
