Reflections in Mammoth Hot Springs

March 14, 2017

Yellowstone National Park (Mammoth Hot Springs). 

This morning was overcast and gray and the sky blended with the off-white terraces at Mammoth.  Blue birds flashed through the drab sky like florescent blue meteorites.


A pair of killdeer were wading through the shallow warm water of the springs, searching for and eating small bugs floating on the water’s surface.  The insects floated through run-off channels, like small canoes in a shallow stream. 


As one killdeer was foraging and wading among the thermophiles, another would make the distinctive and far-carrying "kill-deer" call.  Killdeer are graceful plovers.


The travertine terraces in Mammoth Hot Springs host a variety of thermophilic bacteria including the fascinating Cyanobacteria which uses photosynthesis by day and fermentation by night - as part of its metabolism.
