La Brea (Trinidad): The Island with the World's Largest Asphalt Lake

The **La Brea Pitch Lake** (often called "Lake of Asphalt") is on the island of **Trinidad** (Trinidad and Tobago), in the village of La Brea, southwestern peninsula.

Key Facts

• Size: ~40 ha (100 acres); ~75 m (246 ft) deep at centre.
• Volume: Estimated 10 million tonnes of asphalt (bitumen).
• Origin: Tectonic fault allows deep petroleum to rise; lighter fractions evaporate, leaving asphalt.
• Surface: Firm enough to walk on; "islands" of vegetation float on it.

Significance

• Commercial: Mined since 1867; exported for paving (DC, NYC, London, etc.), roofing, insulation.
• Scientific: Unique microbial ecosystems; analogue for Titan's hydrocarbon lakes.
• Tourism: Guided tours; "healing" sulphur springs at edges.

Other Asphalt Lakes

Smaller ones: Guanoco Lake (Venezuela), Carpinteria (California), Dead Sea (asphalt seeps). La Brea is by far the largest.

Trinidad's "black gold" has paved roads worldwide for 150+ years.
