An Asphalt Lake in Trinidad - natural deposit 250 feet deep!

This article by Business Insider is about a natural lake of asphalt on the beautiful island of Trinidad. At current usage rates, it contains 400 years of asphalt pitch. Because it is so unusual, it is also a tourist attraction, attracting over 200,000 visitors a year. Click the link below to see more incredible photographs.



The Caribbean island of Trinidad is home to the world's largest deposit of natural asphalt, called Pitch Lake.  

The surface of the lake is a mostly solid carpet of asphalt that can be walked on, attracting some 200,000 tourists each year.

The lake is also mined for asphalt — called "pitch" in its crude, unrefined form — sold around the globe for the use in the paving highways, race tracks, bridge decks, and airport runways.

The lake is located next to the village of La Brea, meaning "tar" in Spanish. It measures 250 feet deep at the center and covers a surface area of around 100 acres, or about 75 football fields.

The quality of the asphalt first impressed English explorer Sir Walter Raleigh in 1595, credited with "re-discovering" the lake. He initially used the asphalt to seal his ship. The Trinidadian asphalt held well, even in heat and sunlight, and Raleigh thought it was superior to the Norwegian tar he had been using.
