The Mono County Sheriff's Office has released the name of a snowboarder who died Tuesday after falling from a cliff.

About 3:50PM March 19, 2019, 911 was called by someone who had seen a person falling from the cliffs above Twin Lakes, across from Tamarack Lodge and north of “Hole in the Wall.” Mono County Paramedics, Mammoth Lakes Fire Department and Mammoth Lakes Police Department responded, and hiked to the area where the man had fallen; they determined he died as the result of the fall.

The Sheriff's Office has identified the victim as 31-year-old Justin Khoshnevis of Los Alamitos, California.

The investigation indicates Khoshnevis, who was alone, came across the ridgeline from “Dragon’s Tail,” which is out of bounds from Mammoth Mountain Ski Area. He was possibly attempting to ride “Hole in the Wall,” a backcountry chute, but it is not accessible from that approach. Khoshnevis’ snowboard was found along the path of his descent.

In a statement, the sheriff's office says, "This tragic incident is a reminder that ski area boundaries are established for your safety. Anything outside the ski area boundary is considered backcountry, and the decision to enter the backcountry should be made with great care. Always ride with a partner; have a plan; know your route; and carry the proper equipment."
