Did you know that glaciers are growing – today – in the United States?

Video – “A Dangerous Glacier Grows Inside Mount St. Helens’ Crater”

According to Charlie Anderson, independent geologist and vulcanologist, the crater, officially named Crater Glacier, is growing unusually fast. In fact, its, and is the fastest growing glacier in the continental United States

This video appears to be rather old, but even today Crater Glacier glacier is still growing and advancing at a steady rate of about 25-30 meters per year (80 to 100 feet per year), according to the USGS. The glacier is advancing across the crater floor and dropping into the Loowit and Step Channels.

  1. So, in the same sentence he blames the retreat of other glaciers in North America on global warming, and then says the one in the St. Helens caldera is advancing because it gets so little sunlight. I half expected his head to explode from the short circuit, but he really does not get his own contradiction. I suppose St. Helens is not on Earth.

  2. It is not maybe so surprising.

    When a glacier is in steady state, the rate of melting at the bottom is matched by the rate of increase in mass at the top.

    When you completely remove a glacier through volcanic eruption, the glacier starts to reform at the altitudes where positive mass balance scenarios pertained during steady state of the old glacier, whereas lower down, where the old snouts were, no year-round snow will exist.

    As a result, there will be a growth phase back to steady state, taking however many years that takes.

    So I do not see this as anything but what you would expect: a glacier removed 40 years ago steadily regrowing to retain a steady state position.

  3. Robert,

    I was struck by the caption on the Weather Channel: “Third tropical storm before Hurricane Season?” (I quickly noted it’s not called “Tropical storm” season, but I digress).

    It got me thinking about the last glacial map and how it run along the Canadian border and dips down into the US near the Great Lakes. Always assumed this was because of how the cold fronts normally follow that same path, however, what if increased tropical storms moving into colder air during the “summer” brought heavy snow?

    I know the storms curve along the coast and head to the UK, but could there be a convergence of the tropical storm moisture and arctic air around the Great Lakes area to bring heavy snow in the summer? Just a thought I had.

    Increased underwater volcanic causing more tropical storms, not less, during the “Robert” Minimum.
