A skier was seriously injured after falling 1,000 feet down a Colorado mountain over the weekend as authorities scrambled to respond after numerous 911 callers kept losing a signal. 

The 29-year-old man was visiting South Arapaho Peak, located approximately 50 miles northwest of Denver, Saturday when he initiated a ski descent of Skywalker Couloir, according to the Boulder County Sheriff’s Office.

The man slipped and fell down the mountain, tumbling approximately 1,000 feet before eventually landing on a nearby slope, deputies said. 

Multiple 911 callers were initially unable to reach first responders due to poor cell service on the mountain.  (iStock)

The Boulder County Sheriff’s Office did not immediately respond to Fox News Digital’s request for comment.
