USA 2018 (10), Mud pots and fumaroles. Our next stop for a walk in Yellowstone National Park, this Monday, 19th February, was at the Lower Geyser Basin.
Here we learned more from Drew about hot springs, fumaroles, and mud pots, having already learned about geysers, such as Old Faithful. We saw for ourselves how vegetation and even small birds could thrive in well below freezing ambient temperatures. At 7.30 this morning, it had been minus 2º Fahrenheit, which sounds even colder in Celsius – minus 19º. Photos can show the water vapour/steam – but not the rotten eggs smell of hydrogen sulphide, H2S, (“very poisonous, corrosive, and flammable” – Wikipedia) which invaded the nostrils from time to time, and had done the previous day also.
Regaining our yellow snowcoaches, we found one of those dark red Bombadiers, the precursors of the modern vehicles we were travelling in. Onwards and northwards.
After a short while we reached our next warming hut, Madison Information Station I think, where we took lunch (in the company of a load of snowmobilists) – and were visited by a coyote.
I saw no-one give him/her anything to eat!
