Imagine climbing a spectacular peak considered one of the nation's most difficult alpine climbs.

Now, imagine climbing that same peak using only equipment from 1916.

That is what four climbers accomplished on the Bugaboo Spire — a 3,204-metre peak in the Bugaboos mountain range — last month.

They were re-enacting the first ascent of the Bugaboo Spire — using the same equipment, clothing and eating the same food as the 1916 expedition led by pioneering climber Conrad Kain.

Bryan Thompson led the 2016 expedition, and he spoke with Daybreak South's Chris Walker about why they did it.

"It is widely considered — still considered — the toughest climb ever accomplished in Canada at that time and up until the 40s when rock climbing gear was invented ... he's a bit of a hero of mine."

Thompson's team didn't use any specialized gear instead relying on leather hobnail boots with nails in the sole — and a hemp rope tied around their waists.

They had no helmets, harnesses, crampons, protective holds or ice screws, he said.

But they didn't stop there.

Thompson and his team even decked themselves out in the same clothing — "right down to the union suit long underwear underneath" — and slept in a heavy canvas tent on spruce tree branches and wool blankets.

"They didn't use sleeping bags or mats."

The group used old pots and pans, cooking only food that Kain would have cooked, and eating only what was available at market in 1916.

"Well, it was a suffer-fest, to be honest."

Thompson said the expedition renewed his respect for what Kain accomplished.

"I have a real deep respect for the toughness, the spirit of adventure and the fortitude that these pioneers of mountaineering had when they were going out and exploring Canada's west."

The expedition was filmed and is being turned into a documentary called Hobnails and Hemp Rope.
