The United States Coast Guard (USCG) says crews responded to reports of two hikers stuck on the Makushin Volcano in Unalaska, Alaska, on Sunday morning.
At around 8:30 a.m., the Alaska State Troopers sent the rescue request to the USCG command center in Juneau.
A helicopter crew based at Air Station Kodiak flew nearly five hours to reach the two hikers, one of whom had a leg injury at about 2,000 feet of elevation, USCG said in a release.
Both were airlifted at around 5 p.m. and flown to Dutch Harbor for medical treatment.
