Alaska Range
Alaska Range Introduction The heavily glacierized Alaska Range consists of a number of adjacent and discrete mountain ranges that extend in an arc more than 750 km long (figs. 1, 381). From east to west, named ranges include the Nutzotin, Mentas- ta, Amphitheater, Clearwater, Tokosha, Kichatna, Teocalli, Tordrillo, Terra Cotta, and Revelation Mountains. This arcuate mountain massif spans the area from the White River, just east of the Canadian Border, to Merrill Pass on the western side of Cook Inlet southwest of Anchorage. Many of the indi- Figure 381.—Index map of vidual ranges support glaciers. The total glacier area of the Alaska Range is the Alaska Range showing 2 approximately 13,900 km (Post and Meier, 1980, p. 45). Its several thousand the glacierized areas. Index glaciers range in size from tiny unnamed cirque glaciers with areas of less map modified from Field than 1 km2 to very large valley glaciers with lengths up to 76 km (Denton (1975a).

Alaska Range glaciers extend in elevation from above 6,000 m, near the summit of Mount McKinley, to slightly more than 100 m above sea level at Capps and Triumvi- rate Glaciers in the southwestern part of the range. -

Foraker's Southwest Ridge
Foraker's Southwest Ridge E r ik L e R o y T HE massive southwest ridge of For- aker is a labyrinthine collection of ribs and buttresses which, with mean dering nonchalance, rises out of several different glaciers headed in sev eral different directions. The point of confluence for these subordinate ridges is a 13,800-foot-high spot, essentially a peak itself, known as “The Fin.” The Fin was first noticed and named by the original-ascent party in 1934. It is the guardian of Foraker’s southwest flank. Regardless of where one begins, the Fin must eventually be traversed. Of the three expeditions that have atttempted this lengthy and convoluted ridge, no two have chosen the same beginning line. In 1976 a Portland party gained the ridge that separates the Lacuna from the Yentna Glacier and was headed Finward when a loss of vital equipment prompted them to beat a prudent retreat. This past spring a party from Anchorage ap proached the ridge from the north along the Herron Glacier: they had succeeded in traversing the Fin before a fall, an injury and a rescue made them withdraw.* In early May of this year we chose for our efforts a ridge separating the east and west forks of the Yentna Glacier. This southwest ridge would deposit us, after approximately seven kilo meters of climbing, in a snow bowl at the foot of the Fin about seven kilometers from the summit. After our first few days on the glacier we were still, with blissful ignorance, undaunted by the considerable length involved. -

For the first time in many years, there were fewer Alaskans on Denali than other states. Colorado showed the highest turnout in 2017 with 121 climbers, followed by Washington (108), Alaska (101), and California (69). • International climbers: 421 (35% of total) Fewer foreigners than usual attempted Denali in 2017. Of those that did, the highest number came from right next door in Canada, with 61 climbers. Next in line was Japan with 46 climbers, followed by Germany and Russia, each of which were represented by 30 climbers. • Average trip length Most expeditions took about one day longer than last year, with an overall average trip length of 17.4 days, start to finish. • Average age The average age was 39 years old. The youngest climber to attempt Denali this year was 11 years old, the oldest was 73. -
