Can road goo come from a lake?
Trinidad's Pitch Lake. A true how-it-works story for kids 5–9.
The Pitch Lake story, read aloud
Look at the dark road under us and all the lanes out the window. That black stuff is asphalt, a sticky goo that glues little rocks together to make roads. But can road goo come from a lake? Yes! Far away, on a warm island called Trinidad, there's a whole lake of asphalt!
Here's how it happened. Deep underground, oil slowly squeezes up through cracks in the rock. Near the top, the runny part dries away, and the thick, gooey part stays behind. Over a very, very long time, so much goo pooled up that it made a lake. The top is so firm that guides walk visitors right across it, like a giant trampoline that forgot how to bounce!
Long ago, Native people there showed the lake to an explorer named Walter Raleigh, and his sailors found a use for it. Arr! We smeared that goo on our leaky ship, and it didn't melt in the hot sun! Today people still dig asphalt from that lake. Next time you see a road, guess: could it have started in a lake?
