This is the dramatic moment an injured biker who crashed his motorcycle down the side of a vast embankment was saved by a Good Samaritan.

Lawrence Matt L'Hommedieu, 46, was discovered lying flat on his back near a ravine in the Columbia Gorge, eight miles from his home in Stevenson, Washington, Friday.

L'Hommedieu had ventured out on a motorbike excursion on Thursday afternoon but crashed his bike at around 4-5 pm in thick woodland where he lay, hurt, for 24 hours.

Alive: L'Hommedieu, pictured here, had left his home on a motorbike excursion on Thursday afternoon but crashed in thick woodland where he lay until a passerby spotted him Friday

Anson Service from Vancouver, Washington, was in the area hiking with his wife Angela.

He was driving on the rural DNR 200 gravel road where he noticed a motorcycle over a bank.

According to KGW.com a couple of hours later he saw the bike still lying in the same place and decided to look a little closer and stumbled upon the biker.

He said: 'I kind of had this nagging feeling to pull over. So I stopped and pulled over and hopped out and when I looked over the ravine down to where the creek bed was about 50- or 60 feet down, I saw a fellow laying down there, laying on his back.

The couple hurried down towards L'Hommedieu who was sprawled out on the rocks halfway down a steep embankment.

He was going in and out of consciousness but explained that he'd lost control of his dirt bike and crashed on Thursday, but had been stuck there overnight because he was too hurt to move.

L'Hommedieu said he was riding his bike before he lost control while rounding a corner and went hurtling into the creek.

Team effort: L'Hommedieu wa s dragged out of the ravine and transported by ambulance to the Skamania County Fairgrounds and then by Lifeflight helicopter to Southwest Washington Medical Center

The former navy Seal managed to crawl halfway up the embankment, but soon realized he was stranded on a remote stretch of gravel road connecting Stevenson to the upper Washougal River area.

Service told Oregon Live: 'I'm not a medical professional. But he was in real pain. He was thinking he might have broken his back and his leg. He used his iPhone cord to tie a tourniquet on his leg.'

Angela shot video of the moment her husband came into contact with the injured biker.

Service said that they could not get a cell phone signal, so after going down the ravine to check on him, they had to drive 20 minutes to call medics.

Skamania County Deputies said that EMS and Rope Rescue Teams pulled L'Hommedieu out of the ravine, according to Fox 12.

L'Hommedieu was transported by ambulance to the Skamania County Fairgrounds and then by Lifeflight helicopter to Southwest Washington Medical Center.

A hospital spokeswoman said he was in critical condition Saturday. His mom, Gretchen L'Hommedieu, confirmed that he suffered broken ribs, a collapsed lung and shoulder injuries.

He has already had surgery on his broken leg and is due to undergo a second operation next week.

Gretchen told Oregon Live: 'He said he's never been that cold. He's a lucky dude. We're very grateful.'

The Columbia River Gorge, a canyon, is up to 4,000 feet deep and stretches for over 80 miles.
