At the end of the trail behind Wupatki National Monument’s visitor center, the ground has an odd habit: air can move through a crack in the rock strongly enough for a visitor to feel it. The National Park Service calls these openings blowholes. Here, desert air moves between the surface and a deep, narrow network of fractures.
The nearby Wupatki Pueblo is an important ancestral site for many Indigenous communities and a place that deserves careful, on-trail visiting. The blowhole belongs to that same protected landscape and sits along the pueblo trail, where the park says a 104-room community and a ball court make up the larger site.
A deep, narrow fracture system
NPS describes a near-vertical fault that cut through Kaibab Limestone and Moenkopi Sandstone tens of millions of years ago. Groundwater moving through the fault dissolved limestone and helped create a fracture system that extends for miles beneath part of the monument. Its narrow passages leave much of the underground shape beyond direct human mapping.
The park’s estimate of roughly 7 billion cubic feet comes from measurements of airflow. It provides a useful sense of scale for the unseen fracture system while reflecting the limits of direct mapping.

Why the air changes direction
The blowholes respond to weather conditions. NPS explains that when outside air is cool and dense, air tends to move into the ground. When the outside air is warmer and less dense, air tends to move out. Atmospheric pressure also affects the exchange, according to the park’s natural-resource material. The result can feel a little like a landscape inhaling and exhaling, even though it is ordinary physics acting through an extraordinary piece of geology.
That is why a visitor’s experience can differ from one hour or season to the next. The direction and strength of the airflow change with weather conditions, making the blowhole a vivid connection between the air above the desert and the air within the earthcrack system.
A place where geology and cultural landscape meet
The National Park Service describes the views of specific Ancestral Puebloan residents about the blowhole near Wupatki Pueblo as an open archaeological question. It also notes that Hopi stories describe such openings as a source of wind and the home of the wind god Yaponcha. These perspectives bring together a geological explanation for air movement and living cultural traditions connected to place.
Visitors can appreciate the strange effect from the trail. Wupatki asks people to stay on designated paths, respect the pueblo walls, and leave natural and cultural items in place. The most satisfying way to meet this oddity may be the simplest: stand on the trail, notice the air, and remember that the desert below your feet is more connected than it looks.
