A pre-breakfast hike up the boardwalk on this small island formed by volcanos and lava flows. Everything is a shade of brown from the high iron content. Flora and fauna are sparse. We spotted a couple of lava lizards, a grey-green low shrub on the lower, gentler slopes, lava cacti growing on the roc, and a whispy plant that looks like a mess of dead things.
Mid-morning we went ashore to snorkel. If I was looking for color I
was disappointed. There was no coral, no colorful fish, and even the
parrot fish had subdued colors. The coarse yellow sand stuck to
everything.
After lunch the "host" professor - emeritus in geology at MIT - gave
a lecture on volcanos. Definitions. Must be volcanos 101.
