Photos from Vieques, Puerto Rico

Over the Thanksgiving break, I traveled to Vieques, a small island east of Puerto Rico. Vieques is one of the Greater Antilles, the large Caribbean islands (also including Cuba, Hispaniola, and the main island of Puerto Rico). Its rocks are mainly igneous rocks (both intrusive and extrusive), mantled with a layer of tropical limestone deposited during times of higher sea level. Here's a few photos from the trip.

My morning cup of coffee, and the view to the south over the Caribbean Sea.












A beautiful iguana.

Fine-grained granitic dike ("aplite") cutting across coarse-grained granite, Esperanza.












Epidote pods in metamorphosed basalt. Keys for scale.














Looking the other way on the beach -- to the east. I like seeing cactus near the shore. It reminds me of Baja California, Mexico.
