Rory,
Only have hearsay on the structure. Young girl in the office told me it is probably over 90 years old. My step-son sees the conveyer going regularly, they still load small trucks with 3/4" sized gravel under the left side of the tower. I heard that they are planning to tear it down, that I did verify with the girl in the office. The quarry behind the structures is very active with modern equipment. I saw heavy trucks going in and out all the time I was there. My step-son lives in the vicinity and he hears blasting frequently. Was going to see if I can get some history on it, has to be something listed with the local historical society. Rory let me know if you want more pictures. Most of them are too big to post and I would have to duplicate and mail you the floppies. Only wished I could get more pictures, especially closeups, on the rear of the stuctures.
By the way Rory your member status?????????
