Sunset above Mauna Kea

The upper reaches of Mauna Kea are usually above the clouds, but occasionally high clouds get quite a bit of color after the sun drops behind the mountain's numerous cinder cones or pu'u. This photo was taken from near the mid-level facilities above 9,000 feet, across a "saddle" ridge between two cinder cones. It's a 1/10-second f/4 exposure from a Canon PowerShot S20.
