Summary based on the NamUs case record (MP9504) and 8 other sources
On the morning of October 9, 1993, Thomas Carleton, a 44-year-old psychologist from Skaneateles, New York, embarked on a three-day solo hiking trip into the High Peaks area of the Adirondacks. An experienced hiker and a member of the Adirondack Mountain Club, Carleton was well-acquainted with the challenges of the region. He left his home at 6:00 a.m., planning to stay in lean-tos along the trail, and therefore did not carry a tent or a camp stove. Carleton was a devoted husband and father to a young daughter, and his trip was intended as a brief getaway. He was last seen in Newcomb, New York, wearing hiking attire that included a beige wool sweater or a maroon Gortex coat, olive military pants or navy Gortex overpants, a red wool cap, and hiking boots, and he was carrying a teal-colored backpack.

The last known sighting of Thomas Carleton was by two fellow hikers who shared a lean-to with him on the Indian Pass Trail on the day of his disappearance. He reportedly told them he was heading up Indian Pass. That day, the weather was poor, with rain that later turned to snow overnight, creating hazardous conditions in the wilderness. When Carleton did not return home as scheduled, his wife, knowing his reliability, immediately contacted authorities. This initiated what would become a massive search and rescue operation. For days, New York State Police, park rangers, and hundreds of volunteers scoured the rugged terrain. Searchers discovered that Carleton had signed logbooks at two different locations along his intended route, but these were the last traces of him ever found.

Despite the extensive and methodical search efforts that covered a vast area of the High Peaks, not a single piece of Carleton's clothing or equipment was ever located. The complete absence of any sign of him has been a perplexing and enduring mystery for law enforcement and his family. Thomas Carleton worked as a psychologist at a state prison in Auburn and was highly regarded in his community. His disappearance left a void in the lives of his wife and daughter. The case remains unsolved, with the prevailing theory being that he became lost or was injured due to the severe weather conditions he encountered on the trail. Over the years, the story of his vanishing has become one of the unsettling legends of the Adirondack wilderness, a poignant reminder of the unforgiving nature of the mountains and the fragility of human life within them.
