If you guessed #nipper, you're right! 3 of the boys in this photo fr @librarycongress are nippers, working 5000' below surface in the #Pennsylvania #coalmine #TriviaTuesday #50YearsofMapping
Our coal seam names literally go from "A" to "Zenith". Here is a #WordCLoud of common words used in #CoalSeam names. #TriviaTuesday #50YearsofMapping
#DYK each #CoalSeam can be known by multiple names? A prior example we used was the Pittsburgh, which is also known as the #8 seam. So even though we have 947 unique seams in our database, they are known by 2,247 names! #TriviaTuesday #50YearsofMapping
