This week on the Denali Report, updated statistics on this year’s mountaineering season, plus KTNA’s Phillip Manning speaks with the first all-Lebanese team to summit Denali.



In total, 1,075 climbers have registered to attempt Denali. Of those, 502 are currently on the mountain, and 376 climbs have been completed. There have been 162 summits of Denali so far, making the summit rate forty-three percent. Sixteen people are registered to attempt Mt. Foraker. All sixteen have completed their climbs, and seven made it to the summit, making the 2016 summit rate for Mt. Foraker forty-four percent.


Over the past week, the number of mountaineers who summited Denali increased dramatically. Team Lebanon was among them, and is the first all-Lebanese team to make it to the summit. After they returned to Talkeetna, Phillip Manning spoke with the members of the team.


Denali Base Camp Coordinator Wins NPS Award, Will Head Further Up the Mountain This Year

by: Katie Writer – KTNA

Last week, the Walter Harper Denali Ranger Station awarded Lisa Roderick as the 2015 Mislow-Swanson Denali Pro Award recipient. As base camp manager on the Kahiltna Glacier, Lisa has served as a liaison between air taxi’s, Denali Park Rangers and climbers for 15 years.

This May, she will join the Denali Ranger Patrol up to 14,000 foot camp and beyond to see just what it is that puts that sparkle in the climber’s eyes.

KTNA’s Katie Writer spoke with Lisa in the studio on Wednesday.


Surveyors take Denali down a a notch

Wednesday, September 2, 2015

Just days after being officially named Denali, North America’s highest peak received a new height estimate from the U.S. Geological Survey on Wednesday. The new official height for the mountain is 20,310 feet, a reduction of ten feet from the previous estimate taken in the 1950s.

The mountain itself hasn’t shrunk. Rather, scientists today have more sophisticated means of measuring elevation than in the mid-20th century.

The decision to resurvey the mountain came in 2013, after a radar-mapping tool estimated Denali’s height at 20,237 feet. The USGS says that mapping tool is very useful, but not always accurate for the height of specific objects. The best way to determine the elevation of the summit is to do it the old-fashioned way. The USGS sent a team of climbers with GPS and other tools on an expedition earlier this year. The team reached the summit, placed the instruments, and returned safely.

Denali’s new, slightly lower, height still leaves it comfortably ahead of the continent’s second highest peak, Mt. Logan in Canada.

Four years after stroke and heart attack, mountain guide solos Denali

Wednesday, July 22, 2015

by: Katie Writer


The last climber is off of Denali, and the summer season is now officially over. Out of the thousand-plus climbers that attempt the mountain each year, there are always a few exceptional stories of perseverance and courage. KTNA’s Katie Writer spoke with Doug Nidever about his climb and how it marked an important milestone in his road to recovery.

Doug Nidever has worked as a Professional Guide for the American Mountain Guides Association for decades, guiding rock climbing all around the world. At the age of 58, Doug suffered from a stroke and heart attack that his doctors were not certain that he would survive. With the support of family and friends, Doug slowly recovered.

Four years later at age 62,  Doug soloed Denali. He and a friend had started the West Buttress route together, but turned around at 11,000 feet. Something did not feel right to his climbing partner. Doug flew back to the Lower 48 and spent one restless night at his June Lake, California home. The next day,  Doug returned to Alaska to finish what he had11168185_10153038884471795_4647327177835954563_o started. And that was to give his best shot at reaching Denali’s Summit.

In a interview with Doug shortly after coming off the mountain, Doug reflects on early stages of his recovery. He had to relearn everything, and he means everything.

“Basic things, how to go to the bathroom. You know, you think that would be hardwired into your body, but having to re-learn that. Having to learn how to cook and read and drive and climb and spell and this and every aspect of life.”

In the midst of re-learning life, Doug decided that he was not going to settle for the life in a wheelchair that doctors thought was going to be his reality.  Instead, Doug chose to pursue his “gold standard” of living through his passion for mountaineering.

“Something extra difficult for me to go do something this big by myself with the uncertainties …what have I learned, what have I forgotten, what’s floating in the mix out there…just wanting to see where the boundaries lie.”

Doug says completing the climb by himself was actually a great opportunity to see just where he was at with his recovery from his stroke and heart attack.

“It’s a good completion of a four year struggle to get back to some sense of normality…finding out that I can understand, I can make good decisions, and I can do this somewhat correctly and have it work out.”

In addition to the need for physical fitness, Doug says those decision making skills are critical to safe travel in such an environment where crevasses are a constant hazard.

“One, these are the biggest crevasses on the planet that we live and if you fall in you are probably not coming out. There are a hundred and one different components that go into the decision making there.”<Doug Crevasse Danger>

Doug partially credits his success to his own stubbornness.  Slowly but surely, he progressed 1000’ a day with only a single load carry.  Most climbers shuttle their gear back and forth on the way up. Doug jokes that he’s “kind of a lazy guy,” knowing that his choice of travel was unique.  All of the perseverance in the world only matters in the Alaska Range if Mother Nature cooperates, however. Fortunately for Doug, the weather held, and he made it to the summit on a chilly midnight in late June. After a few minutes, alone, at the highest point in North America, Doug safely descended to his camp at 17, 200’.

11168185_10153038887261795_7524243424079589986_o“You know, so I got to sleep from 4 am until late afternoon. And mill around and see what body parts are sore and what still worked and what didn’t.  A little bit of loss of elevation brings your energy level so far up.

Doug’s solo climb of Denali gives him an appreciation for his own recovery.which he says wouldn’t have been possible without the support of his friends and family.

“Nobody stands alone very well.”




Denali ranger describes patrol and memorable summit day

Currently, there are 1,090 people registered to attempt Denali. Of those, 129 are currently on the mountain, and 945 have completed their climbs. As of Thursday, 533 climbers have reached the summit, making the summit rate fifty-six percent.

All fifteen climbers registered for Mt. Foraker have completed their climbs, with six making it to the summit.

This week on the Denali Report, KTNA’s Katie Writer speaks with Mountaineering Ranger Tucker Chenoweth, who is back after patrolling on Denali:


Good weather on Denali for the past three weeks has increased the summit rate from a dismal 0% in May to a soaring 56% in early July.

Mountaineering Ranger Tucker Chenoweth and a team of four volunteers patrolled the mountain from May 26th to June 20th, and saw the dash for the summit that took place when the weather cleared.

“At high camp, I believe, there was a group – call it, like, a “plug of climbers—that had been stuck at “Fourteen Camp.” So, the first window they had, they all went. (more…)

Denali Height Being Measured By Climbers

Wednesday, June 24, 2015

This story by KNOM’s Francesca Fenzi :

A dispute over the height of North America’s tallest mountain may be resolved this week, as surveyors climb to the top of Mount McKinley.

McKinley – recognized throughout Alaska by its Koyukon Athabascan name, Denali – has long been thought to stand at 20,320 feet, a measurement recorded in 1953. That number was contested in 2013, when the United States Geological Survey (USGS) used radar technology to re-calculate the mountain’s height. The result was a mere 20,237 feet… 83 feet lower than the previously recognized elevation.

“Oh, people didn’t like the lower number. And I was bothered by it myself. I mean I had people say, ‘It’s still over 20,000 feet, I hope?’ And I said, ‘Yes it’s still over 20,000 feet, but I don’t know how much over 20,000 feet.’”

Dave Moune is Senior Project Manager with Dewberry Geospacial Products and Services – a company contracted by USGS to perform the 2013 survey. Moune says the “new” elevation, in addition to being controversial, may not be entirely accurate.

He says the measurement was taken from the air using radar frequencies, to create 3D images as part of an ongoing mapping project around the state. And while that technique is great for mapping complex terrain in 3D, Moune says its single-point elevation measurements could be off by several meters.

He adds the most accurate way to measure height for a specific peak is to use GPS. But for that, you need old-fashioned boots on the ground…

“Hey there, this is Blaine. We’re up at 14,000 feet on Denali on the summit survey expedition.”

Blaine Horden is leading those boots – and a team of three surveyors – to the summit of Denali this week. Their mission: To set the record straight.

As of Monday night, the team had settled in at 14,000 feet… with plans to push for the summit as early as Wednesday. But Moune says the task of measuring a mountain isn’t an easy one.

“These guys are not just taking themselves to the top of the mountain. They are carrying a lot of equipment with them. That all has weight associated with it. Some of it is stuff they have to keep inside their coat so their bodies will help keep it warmer. That all adds to the complexity of the climb.”

 In addition to challenges faced by all high-altitude climbers, the team will need to clear a few logistical hurdles. For example: finding the physical peak of Denali – rock that has been buried under feet of ice and snow.

This is an ambitious goal. No survey of the mountain so far has calculated elevation using its natural peak… all measurements have been taken from ice resting on top of the mountain. Which, Moune says, could have contributed to some level of error in the past.

“People want to know how high is Denali. And perhaps the best we can do is tell them how high the ice and snow is in 2015 on the day that we surveyed it. Recognizing that the thickness of the ice and snow may change whenever it snows and rains up there. Or melts for that matter.”

 Moune says even if Horden’s team also measures from the ice at Denali’s summit, the data they gather will still provide an improved estimate of the mountain’s true height.

The expedition could take as long as three weeks to complete, but Moune reports that the surveyors are currently ahead of schedule – and could begin their descent by the end of this week.
