Sign at Morning Glory titled ‘Fading Glory’ describing the not-so-normal brown color:
“Morning Glory Pool is losing its brilliant color. Through ignorance and vandalism, people have tossed objects into the hot spring, clogging its vent and lowering the temperature. Brown, orange and algae-like bacteria thrive in the cooler water, gradually turning the vivid aqua-blue to a murkier greenish-brown.”
