In a devastating turn of events, 29-year-old American tourist Clara Henderson’s last words to her mother—“Mom, I love you. I’m scared”—arrived by text at 5:12 p.m. local time, just hours before rescuers found her body deep within a lava tube on Mount Agung in Bali. Henderson, an experienced hiker and travel blogger, had slipped off the official trail into a forbidden vent zone, unaware of the lethal hazards lurking below.

Bali’s emergency services mobilized within 90 minutes of her last ping on local cell towers. According to CNN Travel, fifty members of the Indonesian National Search and Rescue Agency (BASARNAS) and volunteer climbers braved sulphur-saturated air exceeding 100 °F and treacherous rockfalls to locate Henderson at around 11 p.m. She was found in a narrow crevice, her phone still warm in her hand.

Mount Agung, monitored by the Smithsonian Global Volcanism Program, has been intermittently active since 2017, with deadly eruptions recorded as recently as last year. Though the summit is officially closed to casual hikers, Henderson—known as @Clara.Explores to her 75,000 Instagram followers—ventured off-path to capture an “epic selfie,” friends told The Guardian. “She wasn’t reckless, just driven by her passion for untouched landscapes,” a former climbing partner said.
Experts warn that even dormant lava tubes can harbor high concentrations of volcanic gases such as hydrogen sulfide and carbon monoxide, which are odorless and colorless but can incapacitate within minutes. Dr. Maya Suryani, a volcanologist at Germany’s Federal Institute for Geosciences, told National Geographic Adventure that “tourists often underestimate how quickly oxygen levels plummet in confined vents, turning them into deadly traps.”

Henderson’s itinerary, shared in her final vlog two days earlier, praised Bali’s lush jungles and unique volcanic topography. “This is the adventure of a lifetime,” she enthused, wiping sweat from her brow on the crater rim. Yet that video also revealed subtle warnings: her guide can be heard cautioned passengers about gas masks and staying within marked boundaries, a safety briefing later corroborated by Bali Tourism Board officials.
Her family back in Seattle was alerted to the emergency when Henderson’s phone automatically sent location coordinates to her mother’s phone via a “Find My” update—a function that saved precious time. “We thought it was a glitch,” said Diane Henderson in an interview with KING 5 News. “Then we saw the text.”

Authorities investigating the case have urged strict enforcement of volcanic exclusion zones. Bali’s Disaster Mitigation Agency (BNPB) announced new drone surveillance and gas-detection buoys to monitor volatile pockets in crater areas. “No one else should pay for blurred lines between adventure and danger,” BNPB’s director said in a statement to Al Jazeera.
This tragedy follows a series of volcanic incidents worldwide: in 2019, five Chilean tourists perished on Villarrica, and earlier this year, a climbing group was nearly wiped out on Japan’s Sakurajima. The U.S. Federal Emergency Management Agency now includes volcanic emergencies in its National Preparedness Goal, urging travelers to “respect exclusion zones and local expertise.”

In the online community, #RememberClara has trended as fellow adventurers share tips: always carry a handheld gas monitor (see recommended models), never stray from guides, and inform family of real-time location shares. Travel writer @GlobalTrekker tweeted, “Clara’s passion inspired us; her fate warns us.”

As Bali’s volcanic slopes quiet once more, rescue teams and local leaders vow to honor Henderson’s memory by strengthening safety protocols, making sure “no more lives are lost seeking the perfect shot,” as one BASARNAS rescuer put it. Diana Henderson plans a memorial fund to provide gas detectors to remote hiking groups—turning her daughter’s final message into a life-saving legacy.
