Hovenweep National Monument - Square Tower (west boundary)

At the head of Little Ruin Canyon in Hovenweep National Monument, Square Tower and other nearby structures make up the Square Tower group and mark where Ancestral Puebloans once lived. Square Tower itself is three stories tall, and this group contains the most structures of the sites at Hovenweep, with as many as 500 people living in this area. Go to Photo Collection

Description This fence separates two grazing allotments, within and outside of Hovenweep National Monument. Grazing has been managed differently on either side of the fence, leading to substantially more impact on the right side, outside of the park.

Description Sagebrush has increased dramatically inside Hovenweep (left side) since 1946 when grazing ceased in the Monument. Vegation outside the park, while still grazed, has also recovered as fewer cows are permitted on the land and the early 1970s saw above-average rainfall. Invasive weeds dominate the area outside the park.

Description Sagebrush continues to recover within the park (left side, no grazing since the 1940s) and outside the park (right side, less intensive grazing). Sagebrush was nearly absent sixty years prior, after decades of overgrazing. Heathly soil biocrust and few weeds are visible within the park, while outside the park, trampling and weeds are more common.
