MOUNT WASHINGTON — New Hampshire authorities Tuesday identified the 57-year-old Massachusetts man who died Monday from a medical emergency while hiking on New Hampshire’s Mount Washington.

He is Gary Muise of Sharon.

Muise was hiking with his two daughters, ages 15 and 18, when he was stricken. One girl stayed with her dad while the other went for help, New Hampshire Fish and Game officer Matthew Holmes said Monday.

The three were on the Tuckerman Ravine Trail when Muise collapsed about 2½ miles from the Appalachian Mountain Club’s Pinkham Notch Visitors Center.

Holmes, of Region One in Lancaster, said an emergency team had just completed a successful overnight rescue of a Rhode Island woman on Mount Madison in the White Mountains when they got the call about 10:30 Monday morning on the Tuckerman Ravine incident.

Holmes said in a telephone interview that it was tough on the teenagers having to witness their dad being stricken, then seeing efforts to revive him fail.

“It was rough. That is always very difficult,” he said.

“Other hikers stopped to help, and AMC staff soon arrived on the scene, but they were unable to resuscitate him,” Fish and Game officials said.
