A 28-year-old man was killed while visiting Muir Woods National Monument in California on Christmas Eve when one of the park’s famous redwood trees fell on him.

Subhradeep Dutta, of Edina, Minnesota, was walking on a marked dirt trail with two other parkgoers when he was fatally struck by the 200-foot-tall tree, officials said.

A woman was also injured by falling debris.

Dutta, according to his Facebook page, appears to be an avid outdoorsman who frequents national parks across the country.

The crash from the towering tree that killed Dutta stunned other hikers in the park Tuesday.

“I initially thought it was like an earthquake or something,” Alex Shepard of New York told KPIX. “I had no idea. I had never heard a sound like that.”

“We were just finishing our hike when we heard this colossal noise — maybe 250, 300 feet away — and watched a huge redwood fall from the hillside down to the trail below,” he added.

Park spokesman Charles Strickfaden said a redwood tree falling is a “very rare and isolated event.”

The wet ground from recent storms may have contributed to the incident, he added.
