Crumpled, ancient Potaro River mountains are a sight to behold when travelling to the Kaieteur National Park to view the magnificent Kaieteur Falls.
These mountains, made of sandstone conglomerate, are part of the Guiana Shield, one of the oldest rock formations in the world, stretching through Guyana, Venezuela and Colombia.
A tributary of the Essequibo River, the source of the Potaro is in the Mount Ayanganna area of the Pakaraima Mountains in the North Rupununi savannahs. (Photos by David Johnstone)
