Last week, officials carried out a daring rescue after a teenager was bitten by a rattlesnake while on a fishing trip “deep in the woods” of the western mountains of North Carolina.

The State Emergency Operations Center sent a North Carolina National Guard Black Hawk helicopter to Avery County, accompanied by rescue technicians from the Charlotte Fire Department.

“The hiker was successfully rescued and is now receiving medical treatment at the hospital,” North Carolina Emergency Management announced in a Facebook post on June 5.

The snake bite victim, Zain Shah, thanked first responders in the comments section.

A timber rattlesnake will prop itself upright and make a rattling noise with its tail when threatened – a warning that it is about to strike. They range in size from about 2.5 to 5 feet on average.

The pit vipers can be found across the eastern United States, with sightings ranging from Texas to Iowa to the Carolinas and north to Pennsylvania and New England, according to the National Zoo.
