The Dunes of Lake Willow is one of those tucked away spots that saves its best feature at the center of the lake. You can literally drive completely around it and miss the massive swirled pattern rocks that are only found at the heart of the park. I am very happy to have visited my friend Ash on a nice 100-degree Arizona day and hike Lake Willow. The overall hilly rock formations were entirely coated with this wavy lined pattern that almost looked like a chart to tell how many years each level was under water. I see faces, animals, and objects in the rock formations....what do you see? It was a great day to be exposed to the heavy desert sunlight and feel the heat beaming off the rocks all around you. Each "Detail" photographs of the rock formations varied from 10-30 feet in actual life and can be printed up to 15 feet wide.
