Cape Central High Photos

Ken Steinhoff, Cape Girardeau Central High School Class of 1965, was a photographer for The Tiger and The Girardot, and was on the staff of The Capaha Arrow and The Sagamore at Southeast Missouri State University. He worked as a photographer / reporter (among other things) at The Jackson Pioneer and The Southeast Missourian.

Come here to see photos and read stories (mostly true) about coming of age in Southeast Missouri in the 1960s.

Please comment on the articles when you see I have left out a bit of history, forgotten a name or when your memory of a circumstance conflicts with mine. (My mother says her stories have improved now that more and more of the folks who could contradict her have died off.) Your information helps to make this a wonderful archive and may end up in book form.


A Blast at the Quarry

Cement Plant Quarry with blast zone marked by box c 1966After I ran photos of the cement plant quarry yesterday, reader Keith Robinson sent me this sequence of photos of the caverns being blasted. He annotated my1966 aerial to show where the blast was centered.

You can see to the right of the “box” the narrow wall that divided the “Blue Hole” from the main quarry. Keith said family friend Burl Medlock made it possible for him to take the photos.

He said the blast used 300 tons of explosives and loosened 1.5 million tons of rock. The surface area was estimated at 6 acres and was up to 200 feet deep. Here’s The Missourian’s version of the blast.

    Minor correction, I stated that it loosed 1.5 million tons of rock.

    Another interesting tidbit; the blast destroyed a six million dollar rock crusher that was located in the bottom of the quarry. The rock face expanded more than expected and engulfed the crusher. I was told that the cost of the crusher was insignificant in light of the profit from the cement that would be produced with the rock released in that one blast and how well it was broken up.

    To add to Keith’s comments with some more detail. The explosive used was Dupont Tovex. A “jelly” that you could squirt out and put a torch to and it wouldn’t burn. Very high tech at the time, and now a staple of quarry blasting.

    The crusher at the bottom of the quarry wasn’t the only thing that got engulfed. A control building for the conveyor that went from the quarry up to the plant itself was taken out as well. But, as Keith pointed out, the rock fractured enough that a couple crushing steps could be taken out of the process which saved much more money than the cost of the lost equipment.

    Once in a while Dad would have to check on something on a Sunday morning after Church, so we would ride down to the plant. It was on one of these times Dad took us into the quarry and into the caverns as there was no work activity. We didn’t get out of the car or go in the caverns very far but it was a neat experience. The ceilings were very high.
    Scott, I assume Burl was your Dad. As I recall he was the General Foreman of the plant. He was always nice to us when we visited the plant. I haven’t been to the plant since Pop retired in 1982.
