History
Pitch Lake has fascinated explorers and scientists, as well as attracting tourists, since its discovery (for the Europeans) by Sir Walter Raleigh in 1595. Raleigh himself found immediate use for the asphalt to caulk his ship. Exported asphalt from Pitch Lake was also used to pave the streets of some regions of New York City.
