Big canyon on a small island

Here's Waimea Canyon, on the west side of the island. This is a remarkably large chasm considering the size of Kauai; the gorge is about half a mile deep on an island of only about 555 square miles. The shifting clouds create constantly changing light patterns on the canyon walls. Though you don't see one here, on a previous visit showers created a rainbow that lasted continuously for over an hour in this area. It's a cool hike down to the bottom of the canyon, but quite steep; I've done it a couple times years ago but them days are probably over the hill for the old sloat.
