The pool at El Morro collects snow melt and rain run-off from the top of the cuesta. Prior to the 1900s, there was a sandbar that rimmed its perimeter. Visitors to the pool could walk or ride their horses around its circumference. Depending on yearly rainfall, today the pool holds approximately 200,000 gallons of water on average.
