A 20-year-old Ocean County man died in a skiing accident at Hunter Mountain in New York on Monday morning, authorities said.

Zachary T. Thompson was skiing on the Racers Edge trail, a double black diamond expert trail when he slid off the course and crashed into trees, New York State Police said in a news release.

Thompson, of the Cream Ridge section of Plumsted, was treated by Greene County paramedics and Hunter area ambulance personnel before being pronounced dead.

A State Police spokesman told TheDailyMail.net Thompson had three or four years of experience.

Thompson graduated from New Egypt High School and was set to enlist in the U.S. Army in the next few weeks, according to an acquaintance.
