Instagram friends, we'd never put coal in your stocking. But if we did happen to do that, we'd probably also have to share some coal history with ya.
This piece of cannel coal came from the Cedar Grove Coal seam in Logan County, West Virginia. Coal powered early industrial America. It was first used to fire steam engines and make steel, later to generate electricity and manufacture chemicals. In 1900 almost 2% of Americans were employed as coal miners.

Reminder: We're closed on December 25 and open the rest of the 364 days each year.
