Montezuma Well, Rimrock

#35 of 196 in Nature in Arizona
Montezuma Well, a detached unit of Montezuma Castle National Monument, is a natural limestone sinkhole near the town of Rimrock, Arizona through which some 1,500,000USgal of water emerge each day from an underground spring. It is located about 11mi northeast of Montezuma Castle.
The Well measures 386ft in diameter from rim to rim and contains a near-constant volume of spring water even in times of severe drought. The water is highly carbonated and contains high levels of arsenic. At least five endemic species are found exclusively in Montezuma Well: a diatom, the Montezuma Well springsnail, a water scorpion, the Hyalella montezuma amphipod, and the Motobdella montezuma leech — the most endemic species in any spring in the southwestern United States.
Montezuma Well's steady outflow has been used for irrigation since the 8th century. Part of a prehistoric canal is preserved near the park's picnic ground, and portions of the canal's original route are still in use today.
As with Montezuma Castle, the label "Montezuma" is a misnomer: the Aztec emperor Montezuma had no connection to the site or the early indigenous peoples that occupied the area.

  • We visited on a wonderful spring Saturday. It wasn't busy at all. It's a paved 1/3-mile loop but it has some steep hills and lots of steps so be aware of that if you have trouble walking. The site is ...  more »
  • It's pretty, the scientific findings about the well are interesting but to be honest it's a little boring because there is not much to see. Anyway, it bothered me that some people where climbing the rocks and taking pictures, and some lady (ranger) threaten to fine us because we where vandalizing the sight, but never bothered to ask if the other people were with us, I guess she just assumed that because they where also Mexican or brown looking like us that we where together.
  • This is just up the road from montezumas castle and it is way more fun if you enjoy an easy hike. Area is beautiful the well is literally a giant hole with a large water source at the bottom. In the sides of the wells walls are ancient cliff dwellings. Along the path are signs indicating important plants to the original dwellers of the area. Very nice. Also some interesting "I was here" graffiti dating back almost 200 years.
