Kittanning Coal
Kittanning coal refers to coal seams in the Kittanning cyclothem of the Pennsylvanian Epoch, located in southeastern Ohio.
In the coal industry, the Lower Kittanning is Coal number 5, and the Middle Kittanning is Coal number 6.
History
These were and are economically important coal seams in the Appalachia region of Ohio. The Middle Kittanning is at about surface level in the valleys of Monday Creek and Sunday Creek in southeastern Ohio, but become much deeper going east.
Many towns and villages in southeast Ohio grew up around the mining of the Middle Kittanning coal vein. Many of these are known as the "Little Cities of Black Diamonds."
gollark: PRAISE THE ACTOR MODEL!
gollark: I have fixed it using the actor model!
gollark: I'm just going to add a hard cap of 20... somethings... executing at once.
gollark: Fun fact: the new version does *not* handle it better.
gollark: I spammed it with a few thousand requests in a few seconds, and:- in the old version it just ignored two increments at once (node.js has a weird single-threaded event loop model...) (the ignoring did come with extra disk/CPU load though)- the version I took down would basically just spin for ages as all the transactions were queued- the new version should have a longer delay and work less badly
