Yellowstone Morning Glory Pool

Morning Glory Pool was a favorite destination for early Yellowstone visitors. It was named in the 1880s for its remarkable likeness to its namesake flower. The distinct color of the pool is due to bacteria which inhabit the water. Although they are too small to be seen with the naked eye, trillions of microorganisms are grouped together and appear as masses of color. They are nourished by energy and chemical building blocks. Colorless and yellow thermophiles grow in the hottest water. Orange, brown, and green thermophiles grow in cooler waters. The Morning Glory bacteria live in near-boiling temperatures, in hydrothermal features with the alkalinity of baking soda, or in water so acidic that it can burn holes in clothing. This classic design is available as a poster, print (framed or unframed), canvas, metal sign, or as a puzzle, set of notecards or postcards, with multiple sizes available for prints, canvases, and metal signs.
