RHH's photos with the keyword: cyanobacteria

Orange Spring Mound is along the Upper Terraces Drive at Mammoth Hot Springs in Yellowstone National Park. It's color is due to orange-tinted cyanobacteria which grow in the water that trickles from the mound. The inset photos are of White Elephant Terrace, just a little ways from Orange Spring, and of some Juniper berries growing nearby.
