Another section of the Montezuma Castle National Monument is the well. It is not attached to main Monument and requires a 15 minute drive. The "well" is actually limestone sinkhole fed by an underground spring. The spring produces 1,500,000 gallons of water per day. Unlike many springs, the water contains high levels of arsenic and is unsafe to drink. If you look at the top left of the picture, you can see a small dwelling in the side of the cliff.
I took this photograph last week at Montezuma Castle National Monument near Rimrock, Arizona. I used a Nikon Z5 camera using a NIKKOR Z 24-70mm ƒ/2.8 S lens (1/125 sec at ƒ/14, ISO 100, 24mm). I edited the image in Adobe Lightroom.
