Tagus Cove is defaced by graffiti. That's probably an understatement. All of the vertical walls are spray painted with ship names, individual names and similar scrawlings. A few are done by scratching or carving into the soft tuft. In a way it's a history lesson - some of the graffiti goes back a hundred years or more - but it's a pretty ugly site and detracts from a beautiful location.

After snorkeling we hiked up a narrow wash to a ridge overlooking a saltwater lagoon, and then fairly steeply along the ridge to a line of spatter cones overlooking 1974 lava flows from an eruption of Darwin Volcano.

There were excellent views north to Darwin, Wolf and Ecuador Volcanos on Isabela Island, and across the Bolivar Channel to Fernadina Island and La Cumbre Volcano. There was steam venting from the summit of La Cumbre.

More than any place so far, the bone-dry Palos Santos was greening up a bit, or at least looked like it might be in the late afternoon sunlight. The thickets on the next ridge had a distinctly greenish tinge to them, where until now it was just grey.

Coming down we found two different Woodpecker Finches, one doing sapsucker behavior. We also encountered our first really belligerent bull sea lion, and had to make an awkward detour around him. I suspect he might have just lost a fight or something; there was no sign of a harem.

After supper, there was mild bioluminescence, but not as dramatic as North Seymour was.
