Exit Glacier

Exit Glacier is a glacier derived from the Harding Icefield in the Kenai Mountains of Alaska [1] and one of Kenai Fjords National Park's major attractions. It is one of the most accessible valley glaciers in Alaska and is a visible indicator of glacial recession due to climate change. [2] [3] Exit Glacier retreated approximately 187 feet (57 m) from 2013 to 2014 and park scientists continue to monitor and record the glacier's accelerating recession. [4]

It received its name for serving as the exit for the first recorded crossing of the Harding Icefield in 1968.

History

In the spring of 1968, the first documented mountaineering party succeeded in crossing the Harding Icefield. Ten people were involved in the crossing, which went from Chernof Glacier east to Resurrection Glacier (Later renamed Exit as the newspaper reported that the group would be descending the "Exit Glacier"). Expedition members included Bill Babcock, Eric Barnes, Bill Fox, Dave Johnston, Yule Kilcher and his son Otto, Dave Spencer, Helmut Tschaffert, and Vin and Grace (Jansen) Hoeman. As noted above, Yule Kilcher, Dave Johnston, Vin Hoeman, and Grace Hoeman were veterans of previous attempts; of the ten, only four–Bill Babcock, Dave Johnston, Yule Kilcher, and Vin Hoeman–hiked all the way across the icefield. The expedition left Homer on April 17, bound for Chernof Glacier; eight days later, they descended Exit Glacier and arrived in Seward. Along the way, the party made a first-ever ascent of Truuli Peak, a 6,612-foot (2,015 m) eminence that protrudes from the northwestern edge of the icefield near Truuli Glacier.

Exit Glacier was one of the major landmarks that President Barack Obama visited during his historic trip to Alaska in 2015. The rapid retreat of the glacier highlights the effects of climate change and how it affects Alaska's coastal glaciers.

Access

The Exit Glacier is especially notable for being a drive up glacier (similar to the Mendenhall Glacier of Juneau). A spur road off the Seward Highway leads to the only road accessible portion of the Kenai Fjords National Park. A system of hiking trails lead to the terminus of the glacier and up to the Harding Icefield itself. Although it is one of the Harding Icefield's smaller glaciers, it is one of the most visited because of its easy accessibility and abundant hiking trails around and above the glacier. Exit Glacier is accessible year-round. Upon the arrival of snow, usually in mid-November, the road is closed to cars but open to a wide range of winter recreation:  from snow machines, dogsleds, fat-tire bicycles, and cross-country skiers. [5]

Ranger-led walks to Exit Glacier are available at 10 am, 11 am, 1 pm, and 2 pm daily during the summer season. These walks are approximately 1–2 hours long. "Ranger Talks" are held in the Exit Glacier Pavilion at 12:30 pm. These last approximately 20–30 minutes. A guided hike to Marmot Meadows along the Harding Icefield trail is also available every day of the summer season at 9 am and lasts 3 to 4 hours. [6]

Climate

Seward 8 NW, is a weather station at the foot of Exit Glacier, near the Exit Glacier trailhead and campground. Exit Glacier has a subarctic climate (Köppen Dfc), with long, cold winters and short, cool summers.

<span class="mw-page-title-main">Mount Ascension</span> Mountain in the state of Alaska

Mount Ascension is a prominent 5,710-foot (1,740 m) mountain summit located in the Kenai Mountains, on the Kenai Peninsula, in the U.S. state of Alaska. The mountain is situated in Chugach National Forest, 6.8 mi (11 km) south of Mount Adair, 3.5 mi (6 km) north of Resurrection Peaks, and 10 mi (16 km) north of Seward, Alaska. The peak is near the mouth of Resurrection River into Resurrection Bay. The name Resurrection, referring to the Resurrection of Jesus, is overused for nearby landforms on the Kenai peninsula, as the mountain to the immediate south is Resurrection Peaks. This Ascension name is a variation of the theme. Mount Ascension's name was proposed in 1968 by the Mountaineering Club of Alaska, and officially adopted in 1969 by the United States Geological Survey. Access to the peak is via the Lost Lake Trail, and mountaineering skills are needed to reach the summit. In clear weather the immense Harding Icefield can be seen from the top. The first ascent of this peak was made October 6, 1968, by John Vincent Hoeman and his wife, Dr. Grace (Jansen) Hoeman.

Precipitation runoff from the mountain and meltwater from its glaciers drains into tributaries of the Resurrection River. The first ascent of the peak was made July 23, 1964, by Don Stockard of the Mountaineering Club of Alaska. The peak was named in 1965 by the Mountaineering Club of Alaska for the first ship ever built in Russian America, the Phoenix, which was constructed in 1794 by Russians in nearby Resurrection Bay. The mountain's toponym was officially adopted in 1966 by the United States Geological Survey.

<span class="mw-page-title-main">Lowell Peak</span> Mountain in the state of Alaska

The months May and June offer the most favorable weather for viewing the mountain. In fair weather, the Harding Icefield can be seen from the summit, as well as Mount Alice on the opposite side of Resurrection Bay. This unofficially named peak takes its name from Franklin G. Lowell and his family who were the first homesteaders to settle the Seward area in 1883.

Aialik Bay, also known as Dora Passage between Harbor Island and the Harris Peninsula, is a fjord on the Kenai Peninsula of Alaska, United States. It has no permanent settlements, but there are two public use cabins located on the bay, one at its head and another at Holgate Arm. The Kenai Fjords lodge also hosts visitors. Aialik Bay is 33 miles south of Seward. The bay received its name from Russians recording the indigenous name as "Ayalyk Bay". It is likely that the bay once terminated at Aialik Sill, by Pedersen Lagoon prior to the year 1700. At this sill, the bay's bottom rises to less than 60 feet below sea level, and is as shallow as 18 feet deep in some places. Aialik Glacier, which has created the bay via the process of overdeepening, has since retreated by 4.5 miles.
