Outburst

Public service announcement from the City of Valdez

An ice-dammed lake above the Valdez Glacier is undergoing an outburst event, which started on Friday. Water levels in Valdez Creek and Valdez Lake will be seeing a considerable rise.

This is a biannual event, which usually happens in mid June and then again in the fall. Water builds up in the lake above the glacier until the pressure raises the ice, and the water flows down the mountain.

Denali National Park & Preserve

National Park Week, Final Day; Today’s Park Theme: B.A.R.K. Ranger Day

Denali and the Alaska Range, view from the south

I think it’s safe to say that I have visited Denali National Park more than any of the others. Of course, it’s only a two hour drive away. Denali is a gem of a Park, and its Mountain and namesake is the crown jewel. Discussions for the area to become a National Park started as early as 1906, and by 1915 there was a solid plan and momentum for the idea. The naming of the Park was contentious from the very beginning, and that should be the subject of a future blog post. Alaskans and Park proponents who had actually visited the area wanted to see the Park named Denali, which was the Athabaskan word for the Mountain. The powers in Washington DC, particularly  Thomas Riggs of the Alaska Engineering Commission, disagreed. The new park would be named Mount McKinley National Park, a decision that Alaskans would fight for decades until it was finally officially renamed Denali National Park in 1980.

A view along the Park Road

At first the new national park was accessed by the Alaska Railroad, which ran between Seward on the southern coast and Fairbanks. The Denali Highway was opened in 1957, giving road access to the Park from the Richardson Highway, which runs between Valdez on the coast and Fairbanks. It wasn’t until 1971 for Anchorage to have direct access to Denali with the building of the Parks Highway between Anchorage and Fairbanks. The Denali Park Road starts at the George Parks Highway, and travels west into the Park for 92 miles. The road ends at the historic mining community of Kantishna.

Teklanika River

There are several trails for hiking in Denali NP, but like the Wrangell-St Elias, this is wilderness, and most hiking is off trail and across country. River crossings are common, and seeing wildlife is (practically) guaranteed. I have one friend who is so wildlife viewing challenged, that other than rabbits and ravens, nothing will show for him. I add the “practically” for those in that exclusive club with my friend in NY.

Caribou in Denali

For the rest of us, wildlife viewing in Denali NP&P is a smorgasbord. I have never been in the Park without seeing caribou and moose, and always grizzly in the summer months. I once took my Dad to Denali and we rode the school bus to the end of the Park Road. While stretching our legs at a rest area, I spotted a wolf sauntering along a river bed, and pointed it out to my Dad and another gentleman who was on the bus with us, and they watched it through my binoculars until we had to board again. I ended up getting scolded by everyone else who was on the bus, because I didn’t hunt them all down and show them the wolf too. Beware of the bus etiquette.

Alaskan Standoff: Grizzly Bear vs Bull Caribou

Denali is a special place in the winter, and I’ve enjoyed snowshoeing the trails and even the roads with the crowds of summer a very distant memory. Dog mushing is a very common activity in the winter, either with your own team, or riding along with a guide. Cross country skiing, snowshoeing and winter camping are the most common wintertime activities. It is a very beautiful, and quiet, winter wonderland. I searched and searched for winter pictures, and I could not find where I stashed them so that I could easily find them again. I will have to go back to create some more.

Denali Park Kennels

Dog mushing teams have been a part of Denali Park since 1922. The Park still maintains and works a team of sled dogs. In non-Covid years, the kennels can be visited, and the rangers give some pretty cool demonstrations. Plus, these dogs are just a lot of fun to hang around; Alaskan sled dogs have developed their own unique personalities, and they love to show them off. Driving the Park Road, you will often see the dog handlers walking the sled dogs, so watch for the signs.

Kenai Fjords National Park

National Park Week, Day IV; Today’s Park Theme: Transformation Tuesday

Map of Kenai Fjords National Park

Kenai Fjords: Where Mountains, Ice and Ocean meet.

Kenai Fjords was first designated a National Monument in 1978. With the passage of ANILCA, the Alaska National Interest Lands Conservation Act in 1980, Kenai Fjords officially became a National Park.

Exit Glacier

Kenai Fjords encompasses 669,984 acres, which includes the massive Harding Icefield, which is the source of at least 38 glaciers.

Exit Glacier and the Harding Icefield can be reached from the community of Seward. It’s a short drive from town to the visitor center and trail head. The short and relatively easy trail takes one to the foot of the glacier. Exit is retreating at a pretty good clip, and is now losing ice during all seasons.

The Harding Icefield

The Harding Icefield covers over 700 square miles, and that does NOT include the 38-40 glaciers that spawn from it. The hike past Exit Glacier to the icefield can be described as strenuous, but the view, when clear, is absolutely amazing.

Harding Icefield is one of four remaining in the United States, and the largest that is contained completely within the country. It receives, on average, 400 inches of snow each year.

Much of the Park is only accessible by water, and sea kayaking is a very popular activity. There are many tidewater glaciers that can be reached from Seward.

Kayakers dwarfed by Aialik Glacier

Two glaciers that I have visited from Seward are: Bear, which is the longest glacier in the Park, and Aialik Glacier, which is a bit more impressive from the water. Bear has receded to the point, that a lake now exists between the ocean and the glacier. The lake is often filled with small icebergs, which makes kayaking interesting. Aialik is a giant ice wall from the water’s surface.

Kenai Fjords National Park received 321,596 visitors in 2018. It is the fourth most visited Park in Alaska, and the closest to the city of Anchorage.

Answer: No, winter has lost its grip. The melt is on.


Glacier on the move

Muldrow Glacier in Denali National Park is surging:

In early March, pilot Chris Palm, who took the photo above, noticed something very different about Denali Park’s famed Muldrow Glacier. The normally smooth surface of the glacier was broken up by crevasses stretching across the width of Muldrow.

The long awaited surge had begun.

The 39 mile long, Muldrow Glacier last surged in 1957, so scientists were thrilled to study a natural phenomenon that has not occurred here in 64 years.

Surge-type glaciers are relatively rare, with approximately 1% of the glaciers world-wide being surge glaciers. Denali National Park has several, most of which get their start from the face of North America’s tallest peak.

Newly formed transverse crevasses on Muldrow

As snow and ice builds up at the higher elevations of a glacier, meltwater is also building up underneath the glacier. This meltwater acts as a lubricant when the weight from above passes equilibrium. The glacier then surges downward at a rate of up to 100 times faster than normal. At some point, the meltwater trapped under the glacier will be released in an outburst flood. Once the water is reduced significantly, the glacier’s surge will slow and it will go back to a state of quiescent (non-surge) once again. Over time, the process repeats itself. Muldrow Glacier has a history of surging roughly every 50 years.

There are two GPS stations on the glacier to monitor its movement. There are also four time-lapse cameras facing different areas of the glacier, including one at the terminus to monitor the glacier’s “bulldozing action”. Another is looking over the McKinley River in order to capture images of the outburst flood. The Alaska Earthquake Center also has a seismic monitoring station, and a sound station has also been installed in an attempt to capture the grinding sound of the surging glacier.

Mapping Muldrow’s movement

In 1957, most accounts have the surge starting in May, 1956 on Traleika Glacier, which is the main tributary of Muldrow. Muldrow Glacier would advance over 4 miles before the surge ended in September of 1957. Approximately 3.3 cubic kilometers of ice was redistributed from the upper reaches of the glacier to its toe. At the upper levels, the ice thickness had dropped as much as 170 meters, but the toe rose to a 200 foot tall ice wall.

Currently, the Muldrow Glacier is moving between 10 to 20 meters per day, and is only 800 meters short of the 1957 terminus. At the current rate of surge, Muldrow will reach the 1957 distance in June.
