Looking Icy

Some of the really spectacular and awe inspiring sights we saw were of glaciers. There are no glaciers in Indiana. It was eerie to see them. They looked unreal. The ice was various shades of blue ranging from a light robin’s egg blue to a stunning deep cobalt blue. This is because the glacier ice is compacted removing air and forming the ice into dense crystals. When light hits the crystals, they absorb red light and scatter blue light. The farther the light has to travel the darker the blue color!

We visited Mendenhall Glacier. The glacier moves about 2 feet per day but is losing volume much faster. That means it is shrinking since loss exceeds any gains from new snow. The visitor’s center had a series of photographs from the 1950s to today – and it is a convincing case for the reality of climate change!

Then we visited Glacier Bay. The cruise ship was only able to get so far into the bay because there were so many ice chunks in the water they were afraid of damaging the propellers! Glacier Bay has seven tidewater glaciers: Margerie Glacier, Grand Pacific Glacier, McBride Glacier, Lamplugh Glacier, Johns Hopkins Glacier, Gilman Glacier, and LaPerouse Glacier. The high tide-water glaciers include Riggs Glacier, Reid Glacier, Lituya Glacier, and North Crillon Glacier. Some of these regularly calve icebergs into the bay! The bay has a weird sound to it – a crinkling like cellophane and a creaking that reminds me of tall trees in a fierce wind. It is the sound of the ice moving and pieces breaking off. I didn’t get a photo of a chunk falling into the water but we heard it!

    1. Caitlynngrace I felt so small. The size of the glaciers doesn’t translate in the photographs. Coupled with the enormity of the sky and the vastness of the water I was nothing more than a speck… Which of course makes God’s personal concern for me all the more amazing…

  1. I love the blue of that glacial ice! The glaciers have really changed in the few years since I was last there — climate change and global warming are really here, and they are affecting the entire globe!

    1. Absolutely. I was so taken by the Mendenhall photo gallery that showed the changes in the last 70 years (since the first photo record was started in 1950). Climate change is real and accelerating faster than even I imagined!!

      1. I hope you also have an opportunity to see (in person or photos) a glacier calving — it’s quite an experience to see huge chunks falling into the water!

        1. I’ve seen some videos. We were in Glacier Bay and there were some chunks that calved – but we were on the wrong side of the ship to see it happen. We could however hear it! (and after it happened we managed to get to that side and people pointed out where it came from and where it was in the water…

  2. awesomely eerie, how amazing … I cycled around a glacier in Norway but it wasn’t melting then so I had none of those scary sound effects. Just awesome grand silence!

    Your graphic pics and description are great Val 🙂

    1. I hadn’t expected the blue color. It almost looked like someone had used blue food coloring on the ice. In my imagination they were mountains of white and clear ice. The reality is much different. There is so much debris in the ice from ground rocks and dirt that when they melt the water turns a chalky color!

      1. Just a little clarification — the rocks and debris sink to the bottom, and the chalky color in the water is from the air bubbles that were embedded in the ice that fell off that made the ice blue!

        1. Ha! No Janet I was talking about the glacial melt – the glacial flour – that makes the streams look milky and the lakes look a bright other worldly blue. We saw this all over and although it was pretty, it was depositing silt and making it hard for the fish… Usually it happens and then subsides but with the glaciers melting so rapidly it is a big issue… As for the air bubbles we really didn’t see that as we were at a distance from where the glaciers calved…

    1. We were outside for a good portion of the time – but with the wind and the cold I was afraid I’d drop my phone. Of course there were all the folks with their fancy equipment and tripods…

  3. I am sure that Mendenhall has, sadly, lost some of its mass since I was there in 2015. My mother was astonished to see the difference between its 2015 mass and that of 1990, when she visited southeast Alaska.

    1. It has! They are taking photos from the same vantage point every year and they started in the 1950s. The glacier is really shrinking rapidly!! The photo evidence points to global warming as a real problem and one that should not be ignored!!!
