This vertigo-inducing footage was filmed by teacher Mark Harrison while climbing the dangerous Mount Lady MacDonald in Alberta, Canada, with his brother Thomas, 31, and two friends.
Shot in July, the video shows the adrenaline junkie balancing along the steep and slender precipice while holding a camera – before running along the rocky summit.
The 28-year-old also decided to dangle over the edge while his friend Sunny Kairon, 25, held the camera.
In 2003, a climber was killed on Mount Lady MacDonald after being hit by an avalanche and in 2007 a hiker died after falling between the mountain and the neighbouring Mount Charles Stewart.
Toronto-born Mark is the vice-principal at a Canadian school in China.
He said: “We saw about six other hikers descending and they told us not to go up further because it was too windy and unsafe.
“But we just carried on because we wanted to assess the situation for ourselves.
“It was really windy up at the top but it just added to the thrill.”
Despite being interested in several adrenaline sports including wakeboarding, Mark does not consider himself an experienced hiker.
He said: “I climb recreationally when I travel but I’m not seriously into it – I just like adrenaline rushes.
“The hike is fairly dangerous and scaling the ridge is a lot safer on all fours.
“Even though I crossed it on two feet, I trusted my own abilities, although when I watched my brother doing it I freaked out.
“It was definitely thrilling to do it - I love doing things most people won’t and taking a few extra risks.”
