A scuba diver died at Lake Tahoe on Monday.

The 63-year-old man, whose name and hometown have not been released, was diving with friends near Glenbrook on Sept. 5. They were exploring the wreckage of the SS Tahoe at a depth of about 360 feet.

“The victim and his diving companions are experienced divers and had completed a similar dive at the same wreckage the day before,” Douglas County sheriff’s deputies said in a statement. “The victim made an emergency ascent to the surface for unknown reasons. When he reached the surface he was unconscious and not responsive.”

His friends and first responders were not able to revive him.

The incident is under investigation.
