The 28-year-old Florida man who miraculously survived an 800ft fall into the icy Crater Lake caldera says he is lucky to be alive.

Tyler Johns, a welder from Bronson, Florida, described the horrifying moments he lost his footing while hiking at the national park embedded in the Cascade Mountains of southern Oregon.

‘We went to Crater Lake to sight see and propped down on a snow bank that I thought was soft,’ Johns told DailyMail.com.

‘I kinda jumped into a snowbank thinking it was soft and then I bounced off of it and then started sliding down on my back headfirst down the embankment.

Tyler Johns, 28, a welder from Bronson, Florida, was at Crater Lake National Park with coworkers when he slipped and fell on Monday

‘I slid for all of 800 feet, spun around and got stopped and had some bumps on my head, laceration on my arm, bruised ribs.’

Johns said he was ‘sore everywhere’ and ‘beat up.’

As his boots were filled with snow, he said had to take them off in order to avoid his feet becoming frozen.

Johns said he put his boots back on in an hour later.

‘I didn’t know if anyone had seen me coming,’ he said.

‘I started to climb back up, 150 feet back up, [but I] couldn’t get any farther because there were no trees or nothing to grab onto.’

Johns fell 800feet 'headfirst on his back' down an embankment and waited six hours for to be rescued. The above image shows a Coast Guard helicopter landing in a parking area to take Johns to AirLink Critical Care Transport

Johns said the angle of the slope, which was between 70 and 75 degrees, made climbing up impossible.

So he waited up to six hours for rescuers to save him.

If it took longer, nightfall would have set in and it would have gotten much colder, Johns said.

Despite his injuries, Johns was back at work the next day.

The fall occurred near Rim Village, which is on the southwestern edge of the caldera, the Coast Guard said.

Responders walked him down the shoreline and assisted the Coast Guard in retrieving him in a helicopter, Oregon Live reports.

The Coast Guard shared that it landed in a nearby parking lot before transferring the man to the AirLink Critical Care Transport team.

The man was flown to Bend for treatment.
