It is almost dark and quite still, a little cool for the tropics but distinctly humid. There's a feint glow on the horizon, and the jungle-filled valley below is hidden under heavy mist ....

Dawn photographed from a tower overlooking the Danum Valley. These photos are in strict time order, reflecting how the dawn developed and the mist rose out of the valley.

Most photos are available at original size and worth (I think) viewing at that scale.
