There are dozens of small islets like the one near Daphne in the photo above. Usually they're near some larger island, but sometimes there's just a rock, alone, out in the middle of the blue. The photo of the zodiac is actually from a couple of days ago, near Floreana, but they both have that sense of immensity: how small these islands are, how huge the ocean is, and how alone we are out here.
That's part of the magic of course. The waters aren't full of yachts and cruise ships; we don't run into other tourists when we go ashore. What we're seeing won't be here tomorrow or next week when the next boats arrive. But there's a loneliness out here that's undeniable; these islands aren't for humans. We're the aliens here.
