The mega-drought that forced 2,500 Ancestral Puebloans to abandon Utah

Hovenweep’s final days

The stone towers of Hovenweep once housed 2,500 Ancestral Puebloans who built a thriving world at Utah’s canyon heads. Then came the mega-drought of 1276.

For 23 long years, crops failed as corn and turkey bones gave way to wild game and “starvation foods” in the trash heaps.

Most fled south by the late 1270s while others fought over what little food was left. At Sand Canyon Pueblo, 34 people died in a final violent clash with signs of cannibalism.

The survivors trekked to New Mexico and Arizona, where they joined other groups to become today’s Pueblo peoples.

Hovenweep National Monument now stands silent, its empty towers telling the tale of a lost civilization you can touch with your own hands.

Hovenweep Reached Its Peak With 2,500 Residents Before Disaster Struck

Around the late 1200s, about 2,500 people lived in six villages across what we now call Utah. The Ancestral Puebloans built most of their stone structures between 1230-1275, with some final logs cut in 1277.

These clever folks made terraces, water basins, dams, and food storage areas to support their farms. They showed off their building skills with square towers, D-shaped homes, round kivas, and multi-story buildings.

Twenty-Three Years Without Rain Changed Everything

A terrible drought hit in 1276 and lasted until 1299, creating 23 years of water shortage across the area.

Some places got almost no rain during this time. Cold, dry winters killed corn crops year after year, leading to food shortages and hunger.

This drought wasn’t just a local problem – it spread across much of the western United States from Oregon to southern California and east to Texas.

Food Supplies Dwindled As Crops Failed Year After Year

Both people and their turkeys ate corn, so everyone needed good harvests that stopped coming.

At nearby Sand Canyon Pueblo, researchers found fewer turkey and corn remains over time, while wild animal bones and emergency foods became more common.

By the late 1270s, villagers faced serious hunger and turned to hunting and gathering as their crops failed. Turkey flocks died off and natural resources ran low.

People Started Leaving Their Homes By The Late 1270s

As things got worse, people began to leave. By the late 1270s, between one-quarter and three-quarters of pueblo residents had left their communities.

At Sand Canyon Pueblo, about 125 to 375 of the 500 people living there at its peak had already moved away.

Tree-ring dates show building stopped in the late 1270s. This pattern happened throughout the Four Corners region as smaller communities emptied first.

Larger Groups Formed For Safety But Created New Problems

People gathered in bigger communities for protection and better resource sharing as the crisis grew.

These larger groups put even more stress on the already struggling environment. Many villages built during the middle to late 1200s added defensive features.

The lack of food and fuel led to fighting between communities over the few resources left, creating a cycle where violence made food shortages even worse.

Violence Erupted At Sand Canyon As Hunger Grew Desperate

At least 34 people died at or near the end of Sand Canyon Pueblo, with at least eight bodies showing clear signs of violent death.

None received proper burials, suggesting Sand Canyon faced attacks from other hungry groups. Researchers found signs of cannibalism at Sand Canyon, also seen at Castle Rock Pueblo.

The village emptied quickly around 1280 as people fled the area and violence increased.

Castle Rock Suffered A Brutal Attack That Left Dozens Dead

Researchers found remains of 41 men, women and children in just 5% of Castle Rock Pueblo that they dug up.

These skeletons showed marks of violent deaths – broken bones, cuts from stone hatchets, and signs of scalping.

Bodies lay scattered around with signs that some had been eaten.

The attackers weren’t outsiders but likely other Puebloans from nearby areas competing for the same scarce food and water.

The Last Buildings Went Up As The Community Collapsed

Workers built Hovenweep Castle, one of the most famous structures, with logs cut in 1277, making it among the last buildings in the region.

Some settlements like Sunny Alcove show very late tree-ring dates of 1271. Most standing buildings today date between 1230-1275, right before everyone left.

These final building efforts show the communities tried to adapt as climate change and growing population stressed them.

Everyone Was Gone From Hovenweep By 1300

The Hovenweep people left their pueblos in the late 13th century as the 23-year drought made life impossible.

By about 1300, the Ancestral Puebloans had completely left the area. This happened across the entire Four Corners region, and the area became nearly empty by 1350.

The Ancestral Puebloans became refugees, simply trying to survive.

Survivors Headed South To Find New Homes

Archaeological and cultural evidence shows people from Hovenweep and surrounding areas moved south to live with the Hopi of Arizona and the Puebloan people of the Rio Grande in New Mexico.

The inhabitants migrated toward the Rio Grande Valley and the Little Colorado River Basin where water was more reliable.

All Pueblo communities throughout the Mesa Verde region moved south and southeast into northern and central Arizona and New Mexico.

Today’s Pueblo, Zuni and Hopi people descended from these climate refugees.

The Name "Hovenweep" Tells The Whole Story

Hovenweep remains one of the best-preserved examples of Ancestral Puebloan architecture in the American Southwest.

Today, 20 different Pueblo groups live in the areas where the Hovenweep refugees migrated centuries ago.

The ruins stand as a reminder of how quickly climate change can destroy even well-established communities.

The name “Hovenweep” comes from a Paiute/Ute word meaning “Deserted Valley,” a fitting label adopted by pioneer photographer William Henry Jackson in 1874.

Visiting Hovenweep National Monument, Utah

You can explore Hovenweep’s abandoned towers where 2,500 Ancestral Puebloans fled during the Great Abandonment mega-drought from 1276-1300.

Take McElmo Canyon Road to the visitor center at Square Tower Group for the $20 entrance fee (cards only). Walk the 1.5-2 mile Square Tower Loop Trail to see the structures they left behind.

The visitor center shows an 18-minute film daily 9am-5pm, plus there’s a 31-site campground for RVs up to 36 feet.
