About
About Walnut Canyon National Monument
Walnut Canyon National Monument preserves 300+ Northern Sinagua cliff dwellings (c.1100–1250 CE) set in shallow alcoves under the Kaibab Limestone rim of a 122m-deep canyon 12 km east of Flagstaff, Arizona, at 2,070 m. The Sinagua built dry-laid sandstone roomblocks in natural caves along 8 km of the canyon wall and agricultural pueblos on the rim above, linked by vertical steps and handholds. The Island Trail descends 56 m to 25 restored cliff rooms with intact roofs, T-doors and sooted hearths that housed maize farming families before abandonment c.1250 during Great Drought stress. Roosevelt proclaimed it a National Monument (1915); NPS curates the largest Sinagua cliff assemblage.
