Still More Airplanes!

November, 2018

We flew into Dulles, Virginia for a wedding in Washington, DC. We decided to go to Dulles first since we hadn’t visited the National Air and Space Museum located there, and Mark seems to be on a mission to visit every airplane or space museum in the country.

Before flying out, though, we spent the night at MSP’s new airport hotel, the Intercontinental, which had opened only a month earlier. It’s not very busy yet, and some areas are not open. There is a bar on the top level of the hotel that provides views of the airport, with airplanes taking off and landing. It’s not open, but we were able to snoop around.

 

The meeting rooms and restaurants are very welcoming, with several options for small groups as well as large. One restaurant has an inventory of games, including a wall-sized Scrabble board, plus pool tables and shuffleboard.

 

For the passenger traveling with carry-ons only, there is a TSA checkpoint on the third floor, so it’s possible to stay indoors all of the way from the hotel to the gate. For the rest of us with checked bags, the hotel provides a shuttle to the terminal.

The Steven F. Udvar-Hazy Center is part of the Smithsonian National Air and Space Museum. It was established in December, 2003 with $65 million in funding provided by Steven Ferencz Udvar-Házy, an Hungarian immigrant who co-founded International Lease Finance Corporation, an aircraft lessor. Smithsonian’s Air and Space Museum on the Mall was not large enough to accommodate many of its artifacts, which were stored off-site.

We had visited DC early in 2003, so this was our first opportunity to see this facility, which is home to the Enola Gay, the Boeing B-29 that carried the atom bomb dropped on Hiroshima, Japan. My father was stationed on the island of Tinian at the time, and recalls seeing the Enola Gay the next day in broad daylight. He also saw “Fat Man,” the name given to the bomb to be dropped on Nagasaki a few days later, although he didn’t realize at the time that this was an atomic bomb.

 

The Space Shuttle Discovery reached its final home here in 2012, after making 39 flights between 1981 – 2011.

 

The museum is also home to a model of the Mother Ship in the movie Close Encounters of the Third Kind. According to the display, the team that made the model added some fun details, such as a Volkswagen bus, a submarine, the R2-D2 android, a US mailbox, an aircraft and a small cemetery plot. I do love a puzzle, so searched for these items while Mark was distracted by air and spacecraft. I did see R2-D2, some aircraft and the cemetery plot, but couldn’t find the other items. Actually, Mark found the cemetery plot as it was above my line of sight.

 

When we returned to our hotel, we arrived at the same time as seven buses of Honor Flight Honorees. We’ve never seen so many wheelchairs and oxygen tanks assembled in one place before. Seriously, we were pleased to see this group from Utah being honored. They were followed by several buses full of junior high hockey players, fortunately all staying in a different wing of our hotel.

We toasted them all at an outdoor firepit.

Frozen Waters Nine: Washington State

July, 2018

This is my final glacier post, at least for now.

We took an airplane flight from Boeing Field around Mount St. Helens and Mount Rainier.

Mount St. Helens has an ancient history of glaciation. When the volcano began to grow about 4,000 years ago, glaciers again developed, and by 1980, there were 22 named glaciers on its slopes. The eruption in 1980 destroyed most of them, resulting in a 70% decrease in glacier mass on the mountain. By September, 1996, there was evidence of a new glacier forming on Mount St. Helens, considered one of the world’s youngest glaciers.

Originally named Tulutson Glacier, and later renamed to Crater Glacier, it wraps around the growing lava dome. Normally, the elevation (6,561 feet) would be too low for a glacier to develop, but the crater walls shade the glacier from sunlight most of the year.

We were able to view Mount Rainier from the air and from land. The mountain has 25 named glaciers. Summit Crater Glacier sits at the very top of the mountain.

When we visited Mount Rainier National Park a few days later, we were able to witness several more, including Nisqually and Paradise-Stevens. Nearby Picket Range is home to a few glaciers as well.

The Picket Range in North Cascades National Park is home to Terror Glacier.

Frozen Waters Seven: Antarctica

February, 2017

Antarctica is the fifth largest continent, covering 5.4 million square miles. There are three ice sheet covering about 98% of the continent, the Antarctic Peninsula Ice Sheet, the West Antarctic Ice Sheet, and the East Antarctic Ice Sheet. This is the largest single mass of ice on Earth, covering an area of over 5 million square miles, and containing over 60% of the Earth’s fresh water. In spite of that, Antarctica is a desert with only about 8 inches of precipitation per year along the coast, and less inland. There are numerous lakes and rivers, even a mountain range, under the ice.

There are hundreds of glaciers on Antarctica, and the weight of the ice has caused the continent to sink by .3-.6 miles. Most of what we saw was from the Antarctic Peninsula Ice Sheet. This ice sheet is widely regarded as sensitive to climate change due to its small size, and because this region has been warming rapidly. Several ice shelves have collapsed in recent years. An ice shelf is the floating portion of a glacier.

I just read a fascinating article on EcoWatch about the ice “singing” to the researchers monitoring vibrations on the Ross Ice Shelf. According to Rick Aster, professor of Geosciences at Colorado State University, “the tones in these signals shift when the surface of the ice shelf is disturbed by changes in surface dunes or near-surface melt.” The noises result when winds blow across snow dunes on the ice shelf.  It’s possible that scientists may be able to predict when ice shelves are about to collapse.

There was a very large iceberg, over 62,000 square feet, that broke off from the Larsen C ice shelf just a few months after our trip. In fact, we had been monitoring the news while we were there, since we knew that this calving was imminent.

In mid-October, 2018, NASA photographed a tabular iceberg that had calved off of the Larsen C ice shelf, that looks like a perfect rectangle, with 90 degree angles. It is rare, but not unheard of, to see an iceberg that looks so perfectly carved as this one.

We saw a small fraction of the glaciers on this continent, yet that was so much more than we’d seen anywhere else. We sailed east and north past Anvers Island, where Palmer Station is located. Palmer is one of three permanent stations on Antarctica maintained by the United States.

Frozen Waters Six: Chilean Fjords

February, 2017

By surface area, 80% of South America’s glaciers are located in Chile. There are five ice fields that feed the multitude of glaciers in Chile.

While cruising around South America, we stopped in Puerto Montt, Chile for a raft ride down the Petrohué River. Puerto Montt is located in the Los Lagos Region, near the northern edge of Chile’s Fjords. One of the highlights of the ride was the views we had of the glacier topped Osorno Volcano.

Further south, near Puerto Chacabuco in the Aisén Province, we saw more glacier topped mountains.

These glimpses merely served to whet our appetite for what was to come as our ship cruised deeper into Patagonia, through the Magallanes and Chilean Antarctica Region. When we reached the Amalia Glacier (also called Skua Glacier), our ship turned around so that passengers on both sides had good views. Amalia, a tidewater glacier, is located in the Bernardo O”Higgins National Park, and covers 61 square miles.

We got much closer to the Italia Glacier in the Alberto de Agostini National Park. Italia is located on a stretch of the Beagle Channel that’s known as Glacier Alley.

The city of Ushuaia, capital of Tierra del Fuego Province, is surrounded by the glacier covered Martial Mountains.

And, at sunset, those glaciers look like molten gold.

Frozen Waters Eight: Antarctic Islands

February, 2017

Decepción Island is the caldera of an active volcano which last erupted in 1970. Over half of the island is covered by thin glaciers. It is also covered with about 100,000 nesting pairs of chinstrap penguins. The volcano keeps the beach and surrounding waters, within about six feet, warm enough for swimming!

 

King George Island is the largest of the South Shetland Islands, with 15 named glaciers, plus more penguins and seals for your viewing pleasure. Our ship took a detour into Admiralty Bay to allow us to see these wonders.

 

Elephant Island is where Ernest Shackleton and his crew landed after having to abandon their ship, the Endurance, while on a mission to reach the South Pole. The ship was crushed by pack ice in the Weddell Sea in 1915, and they were stuck there for about 10 months before sailing three lifeboats to Elephant Island. From here, Shackleton and five crew members took one of the lifeboats to South Georgia Island, and then trekked 21 miles over ice covered mountains to reach a whaling station. Shackleton is the epitome of a hero, managing to keep all 28 members of his crew alive until they were rescued almost two years after they became iced in.

The day was cloudy, but we still managed to see a great deal of ice.

Frozen Waters Five: Hubbard Glacier, Alaska

August, 2016

The largest tidewater glacier in North America, Hubbard Glacier is named for Gardiner Green Hubbard, a founder and first president of National Geographic. (This may be the most links I’ve ever had in one short sentence.) The 76 mile long glacier is joined by Valerie Glacier before it reaches Russell Fjord, with a width of almost six miles and a 300 foot face. It covers over 1,350 square miles of land. At this time, Russell Fjord is joined to Disenchantment Bay, although Hubbard has advanced enough in the past to block the fjord from the bay, and it is expected to do so again.

Approaching Hubbard Glacier from Disappointment Bay

Hubbard Glacier calves regularly, and while we heard it crack and split several times, we were never quick enough to witness the calving. As we approached the glacier, we saw more and more icebergs floating near our ship. There were white bergs, blue bergs, silt filled bergs, and mixes of all three types. We noticed some popping up and down in the water as they split apart.

In 1986, the glacier dammed the outlet of Russell Fjord, creating Russell Lake, where the water rose over 80 feet. A few months later, the dam gave way and more than 5 billion cubic yards of water gushed through in 24 hours, reconnecting the fjord to the ocean. There was another blockage and reopening in 2002. These glacial outbursts can cause serious damage to the landscape, homes and infrastructure in surrounding areas, not to mention the threat to human lives.

The Alaska Climate Adaptation Science Center is monitoring Russell Glacier as well as three other sites, including Mendenhall. The scientists have placed cameras and measuring equipment around these glaciers and lakes to gather data through real-time monitoring. With this information, they hope to be able to warn surrounding communities of impending danger.

Frozen Waters Four: Glacier Bay, Alaska

August, 2016

Before going to Glacier Bay, we took a train ride on the White Pass & Yukon Railway, from Skagway to the Canadian border. The route took us between mountains where we saw several glaciers.

IMG_7108

When explored by Captain George Vancouver in 1794, Glacier Bay was filled with a single great glacier that was more than 4,000 feet thick, up to 20 miles wide, and that extended more than 100 miles. When John Muir explored eighty-five years later, the ice had retreated almost 50 miles up the bay.

Glacier Bay National Park is comprised of over 3 million acres of stunning beauty, in which glaciers play a major role. The park is part of a binational UNESCO World Heritage Site and a Biosphere Reserve. There are eleven glaciers that reach the sea in Glacier Bay. These are tidewater glaciers, defined as valley glaciers that flow far enough to reach the sea. There are only three places in the world where you can see tidewater glaciers: Alaska, Chile and Scandinavia.

Tidewater glaciers calve many small icebergs. Though not as large as Antarctica’s icebergs, they can still cause trouble. We learned from park rangers who came onboard our ship, about different types of icebergs. White bergs hold trapped air bubbles; blue bergs are very dense and hold little air (they absorb white light while reflecting blue); and greenish-black bergs have calved off from the bottom of the glacier, carrying moraine, the rocky rubble picked up along their journey to the sea.

Icebergs come in many shapes as well. There are two basic shapes: tabular and non-tabular. Tabular icebergs have steep side and a flat top, with a length that is at least five times the height (like a large sheet). Non-tabular icebergs have several different shapes: wedge (steep edge on one side and a slope on the other side), dome (rounded top), drydock (with a channel caused by erosion),  pinnacled (with one or more spires), and blocky (similar to a tabular, but the length is less than five times the height).  We didn’t see any large icebergs today.

We passed by Margerie Glacier, which is about 21 miles long, and growing at a rate of about 30 feet per year. This tidewater glacier was named for a French geologist and geographer, Emmanuel de Margerie.

Grand Pacific Glacier is a 25 mile long glacier that is located partly in British Columbia, Canada. This glacier is full of moraine and rocks from landslides that extend across almost two-thirds of the ice face. In some areas, this debris is more than 3 feet deep. The moraine helps insulate the ice, slowing the melting.

 

The approach to Johns Hopkins Glacier is quite dramatic. We caught glimpses of it behind a mountain before we reached the inlet where it’s located. This twelve mile long glacier is one of the few in the park that is advancing.
