Cause of death revealed after 2 hikers, father and daughter, discovered dead near summit of Mount Katahdin
The bodies of Tim Keiderling and his daughter Esther were found near the northern terminus of the Appalachian Trail in challenging weather conditions

The cause of death has been revealed for one of two hikers who were found dead on Mount Katahdin.
The bodies of Tim Keiderling, 58, and his daughter Esther, 28, both of New York, were discovered on June 3 after they failed to return from a day hike. The pair had set off on June 1 from Abol Campground to attempt to reach the summit of Maine's highest peak and were last seen at approximately 10:15am that morning.
A large-scale search and rescue effort was launched after their car was discovered in a day-use parking lot for Mount Katahdin. The mountain forecast at the time called for temperatures around freezing, rain, sleet, and winds up to 40 miles per hour, according to the National Weather Service.
Rescue crews found Tim's body near the summit on June 3 and the following day, teams discovered Esther's body in a steep, snow-covered boulder area between the Cathedral and Saddle Trails off the Tablelands, approximately 1000ft feet from where her father was found.
Now, the Office of the Chief Medical Examiner says she died from blunt force injuries after it appears she attempted to traverse the boulder area slid downhill before colliding with large boulders.
The cause of death of her father is still under investigation.
A Facebook post from Rifton, which specializes in adaptive equipment, says Tim had worked as a sales and customer service representative for the New York-based company since 2020, and Esther joined him in 2023, helping to provide hundreds of in-service and product trainings to customers all over the United States.
