After two days on the island of Trinidad, we are now making the crossing to Guyana on the South American mainland. The sea is shallow and calm, only disrupted by the occasional explosion of flying fish startled by the passage of National Geographic Explorer. The sky is mostly clear and tropical, infinite. Trinidad and Tobago were part of South America until recently – geologically speaking – when the continental glaciers melted and the sea level rose. Biologically, it is still part of South America, as it is bathed in the sometimes turbulent Orinoco River outflow, bringing new flora and fauna from Venezuela. Late this afternoon and into the evening, we relaxed with live local music and the Captain’s Welcome Party. The adventure continues!
