The calcite (473731) shown as from LaFarge Quarry, Buffalo, Scott County, Iowa is from the nearby Linwood Mine, Buffalo, Scott County, Iowa. I have never seen a one similar from the LaFarge, but very typical of the Linwood. Thanks! .....Hal Prior

OK, reluctantly changed it to Linwood Mine. I have never questioned a Neil Pfaff specimen before, but since he labeled it "Buffalo Mine", and the name for the Lafarge Quarry was once Buffalo Quarry, I suppose it is just as possible it is from the Linwood Mine.

The Lafarge and Linwood are just on opposite sides of highway 61 however significantly different in mineralogy. Lafarge is surface quarry, Linwood is underground mine. Watch for a special MR Midwest collectors supplement later this year. Jeff Scovil was a weekend guest at my residence this week to photo Iowa collectors specimens. There will be a number of Lafarge and Linwood items featured, plus some new Iowa locales. I live 45 miles from the two mines and 99.9% certain your specimen is from Linwood, the Linwood also produces the higher quality specimens. I suspect the Buffalo Mine name was the confusion factor. Both mines are located near Buffalo, Iowa. .....Hal Prior

Thanks, Hal - not as reluctant now:-) I knew they were on either side of a highway, so was a little skeptical that you could be certain it was not from Lafarge. Looking forward to the supplement!
