the is a surreal place, after driving miles off the highway with San Fran Peaks in backdrop with snow on top, then you come so several ruins with short trail leading to them. I can only imagine how these cities extisted back then. seems like they would damn the canyon to hold the water and the animals would natural come to them, where they could shoot them with a bow out there bedroom window. i drovbe further to reach the big city complex at the vistor center, where the trail was very short but was a nice walk with no sound. the dry air seem to make the soundwaves not to travel far. The blow hole seem cool, and if they rigged it up, they could of had cold air blowing on them in the middle of summer, but no one really knows. It is a long drive, but is a great get away from flagstaff adventure.
