..is a “thermal feature” a steaming hole in the ground?

It most certainly is.

And Yellowstone, which happens to sit atop a MEGA volcano, is absolutely lousy with them.

...which all have combined to impress the H... out of sentient beings for centuries...

..or occasionally parboil/vaporize the Darwin Award types.

(I seem to recall that The Park bags one or two a year with the springs and the bears get a couple more fools...)

This woman got LUCKY! Multiple folks perish each year by wandering off the boardwalks.

As for the caldera, I live 90 miles north of the park and have a pock-marked piece of lava that was unearthed during a commercial dig at 30’ underground. It’s about 15 pounds and would take a great amount of force to make it travel 90 miles.

Have a great weekend.

Eventually that Yellowstone MEGA volcano will be the death of us all.

Probably not in our lifetime however.
