This is what happens when you ask a geologist to bake a cake. http://blogs.agu.org/mountainbeltway/2011/01/24/east-wall-of-bakers-quarry/ has a very funny description of the quarry and how it was formed. Make sure you read the whole thing!
Historical records indicate that quarrying operations began in earnest around 9:30pm, although there is anecdotal evidence of small scale nibbling, particularly in the Strawberry Granite, prior to that time. Though only crumbs were removed, a few locals reported their findings to others. Resulting hype and rumor-mongering built up public anticipation to a frenzied hum. When the echoes of dinner had faded, industrial-scale excavations began at Baker’s Quarry.
The real Baker’s Quarry is a mine in Monroe, North Carolina, also known as Martin Marietta Materials. This is what it looks like.
