A boiling stream (by mgjefferies)
This stream runs into the Firehole River from the Excelsior Geyser crater and delivers some 15000 to 17000l of water a minute at 93C into the river. Must be a shock to the trout! The colours are due to the various minerals and micro-organisms that are found in this hot environment. The whole bank side is built up by deposits from the water over time.

Another absolutely stunning time-lapse video by Eric Hines. It showcases the skies, geology and landscape of Wyoming, which is surprisingly gorgeous. Worth watching in HD & full-screen.
