The Geological Society of London recently posted an image of a mystery location that the painting's owner would like to identify. Hopefully, zeroing in on the location depicted in this painting will help identify a possible artist. Their blog notes, "The painting dates from c. 1775-1800, and may represent a location in Wales or the Alps." If you want to see more geoscience-related historical images, this month's EARTH Magazine features some of the great images that shaped the field of geology.
