El Morro's small pool of water has drawn people to it's banks literally for hundreds of years. The original natural pool was partly destroyed by a heavy rock fall in 1942, but conservationists rebuilt it to be as natural as possible. In this region of New Mexico, water is rare and sparsely scattered about. Once men knew about this source of water, it continually brought travelers to it's shores for centuries. And.....man decided to leave a record of his visit.
