When Hawaii’s Mount Kilauea’s explosive fury preserved death’s footprints in time

Kilauea’s Deadly 1790 Eruption Preserved Ancient Footprints

Deep in Hawaii Volcanoes National Park lies one of the most haunting reminders of nature’s deadly power.

The Footprints Trail leads visitors to a special shelter where you can see actual footprints preserved in volcanic ash from 1790.

These aren’t just any footprints, but the final steps of families fleeing one of the most explosive volcanic eruptions in American history.

The eruption, called “Keonehelelei” by Hawaiians, killed at least 80 people and possibly hundreds more during a time when rival Hawaiian chiefs were fighting for control of the Big Island.

The fine volcanic ash mixed with rain created a concrete-like mud that hardened quickly in the tropical sun, preserving these tragic footprints for over 230 years.

Here’s the incredible story of how Kilauea’s explosive fury created this unique archaeological site that you can visit today.

Hawaiian Chiefs Fought for Control When Kilauea Erupted

Civil war split Hawaii Island in the late 1700s. Kamehameha ruled the western areas of Kona, Kohala, and Hamakua.

His cousin Keoua Kuahuula controlled the southeastern regions of Ka’u and Puna. Eight years of fighting left the Big Island divided between these rival chiefs.

Keoua recently attacked Kamehameha’s lands while he was away fighting on Maui. Both armies used traditional Hawaiian weapons along with new European guns and cannons.

Hawaiians called this one of the worst civil wars in their history.

Keoua’s Army Took a Risky Shortcut Home

After hearing Kamehameha came back from Maui, Keoua pulled his forces back to his Ka’u stronghold in November 1790.

His group included not just fighters but families, women, children, and older folks who helped the war effort.

Keoua had two choices: the longer coastal path without water or the shorter mountain trail across Kilauea’s sacred summit. He chose the volcano route despite its spiritual risks, wanting speed and access to fresh water.

Warning Signs From Pele Went Ignored

Small earthquakes shook Kilauea’s summit for several days before it blew, showing hot magma moving underground. Steam and gas poured from the main crater, creating a scary mood around the usually quiet volcano.

Keoua’s group camped near the summit, waiting for the volcanic activity to calm before moving on. Hawaiians saw these signs as Pele showing anger, but they needed to get home.

After waiting nervously for several nights, Keoua split his people into three groups to cross the dangerous area.

The First Explosion Caught Families Off Guard

The first blast sent wet volcanic ash southwest across the Ka’u Desert, pushed by the trade winds. Families gathering volcanic glass for tools got caught outside as fine ash started falling from the darkening sky.

The ash mixed with moisture in the air to create thick, muddy stuff that stuck to skin and clothes. Women and children making spear points and cutting tools suffered most.

As ash built up, hundreds ran across the muddy ground, leaving footprints pointing away from the summit.

A Huge Ash Column Reached 50,000 Feet High

The second and biggest explosion shot an ash column 40,000-50,000 feet into the air, visible for many miles.

British sailor John Young, stuck at Kawaihae harbor 30 miles away, wrote about the towering eruption in his ship’s log.

The ash cloud broke through jet stream winds and spread across the island, reaching Kaimu village over 19 miles away.

Near the summit, the eruption threw out coarse sand and gravel-sized volcanic bits rather than fine ash. Strong winds knocked down trees and sent rocks flying across the land.

Thousands of Footprints Show People Panicking

As wet ash piled up inches deep, fleeing families left thousands of footprints in the muddy volcanic material. Scientists who studied the footprints found they came mostly from women and children, not Keoua’s warriors.

About half the footprint trails point back toward the summit, showing some people first ran the wrong way during the chaos. The fine volcanic ash mixed with rain created cement-like mud that captured perfect prints.

Hot sun and dry desert conditions hardened the ash within hours, saving the footprints for centuries.

Superheated Gas Clouds Killed Instantly

The final explosion created a collapsing eruption column that made ground-hugging waves of superheated gas and debris. These deadly surges raced across the summit’s western side faster than anyone could run.

The surges carried poison gas, hot steam, and volcanic debris heated above 1,000 degrees. Death came almost instantly for anyone caught in the path of the racing hot cloud.

Some victims were found holding each other, knocked down by powerful winds moments before the deadly heat killed them.

The Middle Group of Warriors Died Completely

Keoua’s second group of warriors camped upwind near the summit, right in the path of the deadly gas surges.

The entire middle group died, with counts from 80 people to several hundred, making it America’s deadliest volcano disaster.

Rocks weighing tons flew over half a mile from the crater, showing how powerful the explosion was. The first and third groups, traveling at different times, escaped the deadly surges and kept going safely toward Ka’u.

Nobody ever found the victims’ bodies, likely buried under volcanic debris or completely burned by the extreme heat.

The Disaster Helped Kamehameha Win His War

News of the disaster reached Kamehameha, who took it as a sign that the war god Ku favored him. The huge loss of Keoua’s forces tipped the military balance toward Kamehameha after years of standoff.

Hawaiians believed the volcanic disaster showed Pele’s judgment against Keoua’s army. Kamehameha used this to convince other chiefs that the gods backed his claim to rule all Hawaii.

Hawaiians named the eruption “Keonehelelei” or “the falling sand,” marking its unusual explosive nature.

Hardened Mud Kept a Moment Frozen in Time

The muddy ash hardened quickly in the hot sun and dry conditions of the Ka’u Desert. Over 1,700 individual footprints survived across multiple layers of volcanic ash from the eruption.

The footprints captured the final moments of fleeing families, creating a sad record of the disaster.

Volcanic ash layers containing small round particles showed signs of multiple explosion phases within hours of each other. The preserved tracks stayed hidden in the desert for over 200 years until scientists found them.

Modern Science Uncovered the Truth Behind the Footprints

Geologist Ruy Finch stumbled upon the footprints in 1920 while checking out a separate 1919 eruption at Mauna Iki.

The site joined the National Register of Historic Places in 1974, recognizing its unique historical and scientific value.

Modern forensic analysis confirmed the footprints came primarily from women and children, not Keoua’s warriors as long believed.

Recent studies showed the footprints exist in multiple ash layers, indicating some may predate the 1790 eruption.

The site reminds us that Kilauea’s explosive potential poses ongoing threats to modern Hawaiian communities.

Visiting Hawaii Volcanoes National Park

To see the preserved footprints from Kilauea’s deadly 1790 eruption, head to Hawaii Volcanoes National Park. The 0.8-mile trail from Ka’u Desert Trailhead on Highway 11 takes you to the Footprints shelter where ancient Hawaiians’ final steps were frozen in ash. The park is open 24/7 with the Visitor Center open 9am-5pm.

Entry costs $30 per vehicle for a week, or get the $55 Tri-Park Pass. Bring extra water and sun protection as the desert area gets hot. Find the trailhead between mile markers 28-29 south of Hilo.
