Show visitors walk safely on island of trinidad lake all lakes arent filled with water on the island of trinidad off the coast of south america there is an asphalt lake covering more than a hundred acres the surface is brownish black and wrinkled like an old piece of leather people can walk on the lake without sinking their feet leaving only faint prints men work on the lake digging out the asphalt to ship to all parts of the world A railroad track is laid across the surface to the place where here the digging is going on each morning the hole made the day before is filled up and the railroad track sunken and twisted from the movement of the asphalt during the night for a long time says a writer in the washington star it was thought that there was no end to t the supply of asphalt but during the last 50 years when tons of asphalt have been removed the surface of the lake has dropped SO feet it will take many many years to use up the supply but some day in the far distant future mankind may have to think up some new substance with which to surface his streets |
