Wupatki National Monument - This site also contains a geological blowhole. A blowhole is a rare geologic feature in which air is blown through a small hole at the surface due to pressure differences between a closed underground system and the surface. It is estimated that the closed underground passages have a volume of at least seven billion cubic feet. Wind speeds can approach 30 miles per hour.
