A heartbreaking mountain tragedy has taken the lives of two young Colorado climbers after a days-long search ended with investigators uncovering a fatal equipment failure during their expedition.

Kaden Matsuda, 19, and Jackson Donlon, 20, students at Colorado Mountain College, were reported missing after setting out on a hiking and climbing trip near Ice Mountain in Chaffee County, Colorado, on October 23, 2026.

Their bodies were discovered several days later in a basin of West Apostle Mountain.

Authorities have now revealed that a rappelling anchor system suffered what investigators described as a “catastrophic failure of unknown cause,” causing both climbers to fall a substantial distance.

The deaths have devastated their families, friends and college community.

Days-Long Search Ends in Tragedy

The two students left Colorado Mountain College’s Leadville campus on October 23 for an expedition in the Ice Mountain area.

They were expected to return within a few days but failed to come back.

After receiving reports that the students were missing, the Chaffee County Sheriff’s Office launched a search involving ground crews, aircraft and trained rescue personnel.

The search became increasingly difficult as heavy snowfall covered parts of the mountainous terrain.

Investigators eventually located Matsuda’s vehicle near the trailhead, helping narrow the search area.

However, there was still no sign of the two climbers.

Collapsed Tent Found Beneath Heavy Snow

During the search, an aerial team spotted an object near Lake Ann that initially appeared to offer a possible clue.

Ground searchers later discovered that it was the students’ tent, which had collapsed under the weight of accumulated snow.

Inside were sleeping bags, a stove and clothing.

However, neither student was found near the tent.

The discovery increased concerns about their safety as rescue teams continued searching the surrounding mountain terrain.

The region had experienced significant snowfall, with some areas receiving between one and two feet of snow and deeper accumulations caused by drifting.

Bodies Discovered in West Apostle Mountain Basin

On Wednesday, October 28, search teams located the bodies of both students in a basin of West Apostle Mountain.

The Chaffee County Sheriff’s Office confirmed their identities as Kaden Matsuda and Jackson Donlon.

The discovery brought an end to the search but left investigators with important questions about what happened during the expedition.

The Chaffee County Coroner’s Office subsequently conducted autopsies and determined that both men died from blunt-force injuries.

Officials said the injuries were consistent with a substantial fall.

Investigators Reveal Catastrophic Rappelling Anchor Failure

The investigation uncovered a critical detail about the accident.

According to the Chaffee County Sheriff’s Office, Donlon was beginning to rappel using a primary anchor attached to a rock surface.

The anchor system reportedly included a piton and a secondary anchor as backups.

Matsuda was also connected to the same anchor points through his personal anchor device.

Investigators determined that the anchor system experienced a catastrophic failure for reasons that remain unknown.

Both climbers then fell a substantial distance.

The coroner’s findings indicated that the men died instantly from their injuries.

Authorities have not established precisely why the anchor system failed or whether any particular equipment component was defective.

Heavy Snowfall Complicated the Search

Although snowfall made the rescue operation extremely challenging, authorities have not confirmed that weather caused the fatal accident.

The region experienced heavy snow during the period when the students were missing.

The snowfall made it harder for search teams to reach certain locations and identify tracks or other evidence.

Investigators continue to distinguish between the weather conditions that complicated the search and the anchor failure identified during the investigation.

The exact circumstances leading to the equipment failure remain unknown.

Experienced Climbers Who Loved the Mountains

Both students were remembered as passionate outdoorsmen who enjoyed exploring Colorado’s high mountain terrain.

Their planned expedition involved Ice Mountain, a technically demanding peak in the state’s Collegiate Peaks region.

The sheriff’s office described the young men as individuals who loved the freedom and beauty of the mountains.

In a statement, Sheriff Andy Rohrich expressed condolences to their families and friends.

He also noted that the students had spent their final moments together in the high peaks they loved.

A Tragic Reminder of the Risks of Technical Climbing

Rappelling is a technique used by climbers to descend steep rock faces using ropes and anchor systems.

These systems depend on multiple components working together, including ropes, harnesses, connectors and secure anchor points.

Even experienced climbers can face serious risks when an anchor system fails.

The Colorado tragedy has renewed attention on climbing safety, equipment inspection and the importance of carefully assessing anchor systems before beginning a descent.

However, investigators have not identified a specific equipment defect or established whether human error contributed to this accident.

Investigation Details Released

The Chaffee County Sheriff’s Office and coroner’s investigators have provided details of the fatal fall, including the apparent failure of the rappelling anchor system.

The precise cause of that failure remains undetermined.

For the families of Matsuda and Donlon, the discovery of their bodies brought an end to an agonizing search but also confirmed the loss of two young lives.

Their deaths are a devastating reminder of the dangers of technical mountain climbing, even for people with experience and a deep love of the outdoors.
