Bob:
You and I toured an anthracite mine near Centralia, PA, on the way home from
the NASG Convention in Syracuse in 1981. I hope that is not the meaning of
"several years"...! <GRIN>
BTW, I think the guide was practicing a bit of hyperbole about hardness.
Anthracite is definitely the hardest coal but there are many minerals harder
than Anthracite before you get to diamonds. Check out a Mohs hardness scale...
Beyond the Reading, the DL&W based "Phoebe Snow" and "Route of Anthracite" PR
campaign on that hard coal's tendency to burn with very little smoke, soot or
ash.
Thanks for stirring the thread, I spent some enjoyable time flipping through my
DL&W steam photos and trip slides last night!
