Olivine beach at Punta Pitt
This is a view of the beach at Punta Pitt on San Cristóbal Island in the Galapagos. The beach is seen from our hike up and over the peak of the island.
The color of the beach is due to olivine (iron magnesium silicate), which adds a green tint to the sand. (Or maybe I got the color balance wrong.)
