Drake's Well, a modern memorial to the discovery of oil by Edwin Drake (1859)

Drake's Well, PA is a lovely little park on the site of Edwin Drake's first oil well. A reproduction stands near the river. The 'derrick'—the most visible part of a typical oil well—is only used during the drilling of the well. Its height provides the power and maneuvering height necessary for handling the drilling rods. Although the derrick can then be removed, it seems seldom to have been so, judging from the many photographs I've now seen.
