Hovenweep National Monument [CO]
The Hovenweep National Monument consists of six prehistoric ancestral Puebloan villages on an expanse of 26 miles of land. The site was first inhabited more than 10,000 years ago by a farming people. The eventual abandonment of the villages is believed to have been instigated by a lengthy drought.
The monument offers talks, guided walks, interpretive programming, and Junior Ranger activities. Guided walks and interpretive programs are only available for groups and with advance notice. The website offers field trip plans.
