Pumpkin Springs
About Pumpkin Springs
Pumpkin Springs is a mysterious, warm pool of water that sits just above the Colorado. The springs, although occasionally inviting, contain high levels of arsenic, copper, zinc, and lead. The water is poisonous. It is not advised to touch the pool.
There is nice jump rock just upstream of the springs. You can pop into the Colorado and swim back to the eddy where you park your boats for the walk up to the springs.

The tantalizing Pumpkin Springs contains among other things, very high quantities of arsenic.
