Crater?

I thought a crater happened when a big rock hit the Earth.  In Midway, Utah, they claim that a crater can also form when water gurgles up from deep inside the Earth and makes a big hole. 

The Homestead Crater is 10,000 years old, formed by a mineral-rich hot spring that eventually made a big hole full of hot water.  About 135,000 gallons of water flow into the spring each day.  The water occasionally overflows out of the top of the big hole, which looks like this. 

That's a bridge traversing the top of the hole.  It's a little unnerving to stand on it.  Down below, there's a 65-foot deep hot spring for swimming.  It smells a little bit like dirty laundry, but it's also a very pretty color.  

The water is about 90 degrees.  Bathers seemed to enjoy it, but they also turned pink from the heat and moved very slowly.  

One cool thing about a deep hole filled with warm water is that a resort company can take it over and turn it into a scuba certification spot.  Here are the scuba folks, sweating their way to a certificate.  

Miners in the area used this hot spring to rinse off after a long day at the office.  The bottom layer of the hole contains about 10 feet of silt.  Divers have found lots of stuff in that silt, such as guns and coins that probably fell out of the miners' pockets.  

The resort company that bought the crater also put a hotel nearby.  It's a nice spot for weddings and conversations with bronze frogs on benches.  

Rating of this crater:  Five beads of sweat and a skeptical furrowing of the brow.
