It would take 25 Statues of Liberty…

The glacier that sat on what is now the Iowa Great Lakes area was called the Des Moines Lobe of the Wisconsin Glacier, and it was huge!

It carved out the lakes, left behind kames and eskers and created fens and kettleholes. It's hard to imagine just how much ice there was to have created such huge landscape features. The glacial trail inside the Dickinson County Nature Center takes a look at just how deep a glacier is compared to some of the tallest buildings in the world. Let's check it out here!

(Fen, esker, kame --- what do those words mean?)

An average glacier is 1-2 miles deep, so let's say average that out 1.5 miles, or 7,920 feet deep.

The tallest building in the world right now is Burj Khalifa, a skyscraper in Dubai, United Arab Emirates, and it is 2,722 feet tall --- one-third the height of a glacier.

One World Trade Center in New York City stands even smaller, at 1,776 feet tall.

You are probably also familiar with the famed skyscraper called the Willis Tower (formerly the Sears Tower) in Chicago. It is only 1,729 feet tall.

The Stratosphere in Las Vegas has made a name for itself with its death-defying rides atop it, but it's really not all that tall when you compare it to a glacier. The Stratosphere is on 1,149 feet tall.

The Eiffel Tower is another majestic landmark that is dwarfed in comparison to a glacier, because this famous Paris structure is only 1,063 feet tall.

The Gateway Arch is iconic in St. Louis, MO, but it is only 630 feet tall.

The Statue of Liberty seems awe-inspiring when tourists visit in New York City, but 25 of them would have to sit on top of each other to equal the depth of an average glacier.
