CANARY SPRINGS (Mammoth Hot Springs)
So named for its bright yellow color, Canary Springs owes its brilliance to sulfur-dependent filamentous bacteria. The colors blend here in delicate tints on the creamy rock face.

All the Mammoth Hot Springs terraces are formed when water ascends through the ancient limestone deposits of the area. The results are striking and unique. They invoke a landscape that resembles a cave turned inside out, with its delicate features exposed for all to see. The flowing waters spill across the surface to sculpt magnificent travertine limestone terraces.
