Due to activetectonic uplifting, Mount Logan is still rising in height (approximately 0.35 mm (0.014 in) per year).[10] Before 1992, the exact elevation of Mount Logan was unknown and measurements ranged from 5,959 to 6,050 m (19,551 to 19,849 ft). In May 1992, a GSC expedition climbed Mount Logan and fixed the current height of 5,959 m (19,551 ft) usingGPS.[8][11][12]
Temperatures are extremely low on and near Mount Logan. On the 5,000 m (16,000 ft) plateau, air temperature hovers around −45 °C (−49 °F) in the winter and reaches near freezing in summer with the median temperature for the year around −27 °C (−17 °F). Minimal snow melt leads to a significantice cap, almost 300 m (980 ft) thick in certain spots.[9]
Mount Logan is not readily visible from the surrounding lowlands or the coast, due to its position in the heart of theSaint Elias Mountains, although it can be seen from 201 km (125 mi) out to sea.[25] Pictures taken acrossYakutat Bay to the south southeast suggest it is visible from near Yakutat. Its first reported sighting was in 1890 byIsrael C. Russell, during an expedition to nearbyMount Saint Elias, from the crest of the Pinnacle Pass Hills (60°9.5′N140°18′W / 60.1583°N 140.300°W /60.1583; -140.300). He wrote: "The clouds parting toward the northeast revealed several giant peaks not before seen... One stranger, rising in three white domes far above the clouds, was especially magnificent".[26][27] Russell gave the mountain its present name.
In 1894, Mount Logan's elevation was determined to be about 5,900 m (19,500 ft), making it the highest known peak in North America at the time.[28] In 1898, Denali was determined to be higher.[29]

In 1922, a geologist approached theAlpine Club of Canada with the suggestion that the club send a team to the mountain to reach the summit for the first time. An international team of Canadian, British and American climbers was assembled the following year, initially planning an attempt in 1924 but forced by funding and preparation delays to postpone the trip until 1925. The international team of climbers began their journey in early May, crossing the mainland from the Pacific coast by train. They then walked the remaining 200 km (120 mi) to within 10 km (6.2 mi) of the Logan Glacier where they established base camp. In the early evening of June 23, 1925, Albert H. MacCarthy (leader), H.F. Lambart,Allen Carpé, Norman H. Read,W.W. Foster, and Andy Taylor stood on top for the first time.[30][31] It had taken them 65 days to approach the mountain from the nearest town (McCarthy across the border in Alaska), reach the summit, and return, with all climbers intact, although some of them suffered severe frostbite.[32]
1957East Ridge. Don Monk, Gil Roberts and three others (US) reached the East Peak on July 19 after a 24-day climb.[33][34]
1959East Ridge, second ascent and firstalpine-style ascent,Hans Gmoser and five others (Canada). Starting fromKluane Lake, they hiked and skied 160 km (100 mi) to reach the base of the mountain. They climbed the ridge in six days and summited the East Peak on June 12.[35]
1965Hummingbird Ridge (South Ridge). Dick Long,Allen Steck, John Evans,Jim Wilson, Franklin Coale Sr., and Paul Bacon (US) over 30 days, mid-July to Mid-August.Fred Beckey remarked: "When they got back we just couldn't believe that they had climbed that thing. We didn't think they had a chance".[36] This climb is featured inFifty Classic Climbs of North America. As of 2023 the climb remains unrepeated.
1967, July, the first traverse of Mt. Logan was made by Vin Hoemann and Will Harrison, starting at the "HubSew" ridge over the main summit. Team members Alexander Bittenbinder, David Shaw, and Edward Ward joined them via the East Ridge.[37]
1967, August, the first ski descent of the mountain was made in two stages byDaniel C. Taylor main summit to the Kluane glacier[38]
1977Warbler Ridge. Dave Jones, Frank Baumann, Fred Thiessen, Jay Page (all from Canada) and Rene Bucher (Swiss) in 22 days.[39]
1978 West Ridge. Steve Davis (WA), Jon Waterman, George Sievewright, Roger Hurt (NH). Climbed ridge in 27 days "capsule-style".[40]
1979Northwest Ridge Michael Down (CA), Paul Kindree, John Howe, Reid Carter and John Wittmayer climbed to the summit over 22 days, topping out on June 19.[41]
1979South-Southwest Ridge. Raymond Jotterand (CA), Alan Burgess, Jim Elzinga and John Lauchlan reached the summit after 15 days of climbing on June 30 and July 1.[42]
1986 First winter ascent by Todd Frankiewicz, Willy Hersman, Steve Koslow, George Rooney,Vernon Tejas and John Bauman via theKing’s Trench Route on March 16.[43][44]
1987 David Cheesmond and Catherine Freer disappeared while attempting to repeat theHummingbird Ridge.[45] Their bodies were not found until 2000. Due to the remoteness ofHummingbird Ridge, they have not been able to be recovered.[46]
1992 June 6, an expedition sponsored by the Royal Canadian Geographic Society confirmed the height of Mount Logan using GPS. The leader was Michael Schmidt, with Lisel Currie, Leo Nadeay, Charlie Roots, J-C. Lavergne, Roger Laurilla,Patrick Morrow, Karl Nagy, Sue Gould, Alan Björn, Lloyd Freese, Kevin McLaughlin and Rick Staley.[11]
2005 late May. Three climbers from theVancouver-basedNorth Shore Rescue team became stranded on the mountain. A joint operation by Canadian and American forces rescued the three climbers and took them toAnchorage, Alaska for treatment offrostbite.[47]
2017 May 23. 15-year-old Naomi Prohaska reached the summit, the youngest person to do so. She was part of a team led by her father.[48]
2018 June 14. The first all US veteran team reached the summit. The six-person team was unguided and part of the US non-profit organization Veterans Expeditions.[49]
In January 2020, due to the cost of search and rescue operations in recent years,Parks Canada announced new rules for climbing Mount Logan:
No solo expeditions
No winter expeditions (which also includes all of Kluane National Park)
Climbers must have insurance to cover the cost of search and rescue.[50]
There had been eight rescue missions in the previous seven years in Kluane National Park. Each mission typically cost between $60,000 to $100,000 CAD which is paid for by Canadian taxpayers. A Parks Canada spokesperson said the new rules are to help reduce the financial burden to taxpayers.[50]
X-Men writerChris Claremont was inspired by Mount Logan for the adopted name of the superheroWolverine; Claremont said in an interview that "the idea was the tallest mountain being the name of the shortest character".[55]
