Desiree and I drove home by way of a loop through Yellowstone National Park after my teaching engagement there.
A great choice, that. We managed,
among other things, to walk the boardwalk that loops through the steaming
features at Grand Prismatic Spring.
Grand Prismatic Spring looks like
something spilled from another world—with bold hues painted in unnatural
patterns and steam sweeping back and forth above the water. That water,
impossibly clear and hot enough to boil an egg, pulses with color: deep blue at
the center, then rings of green, yellow, orange, and rust—each band the result
of heat-loving bacteria doing what they’ve done for millennia. It’s the largest
hot spring in the United States, but it’s the colors that are most impressive.
I’m posting photographs taken along
the boardwalk at Grand Prismatic Spring.
