What are glaciers?
Glaciers are huge, slow-moving, masses of ice. Formed by years of fallen snow that have compressed into ice, these ice masses eventually begin to flow along the land due to gravity. This movement is what sets glaciers apart from ice beds. It also makes them one of nature’s most dramatic – and fascinating – forces.
We’ve seen these glistening giants countless times on our trips and they continue to take our breath away every time. A must-see for every adventurer and nature lover, here are 10 fun facts about glaciers:
1. The eastern Arctic houses the biggest and oldest glaciers in Canada. A remnant of the Laurentide ice sheet, which covered much of Canada during the last glacial period of the Earth’s current ice age, the Barnes Ice Cap in Baffin Island contains Canada’s oldest ice. Some of it is more than 100,000 years old! Chech out our
2. The Penny Ice Cap in Auyuittuq National Park in Iqaluit is the largest ice mass in the southern Canadian Arctic. It covers approximately 6,400 km2. Researchers have been studying this ice cap for years. Measurement of the Penny Ice Cap is important for researchers to understand the changes of glaciers, especially with climate change and the increased melting over the past decade.

4. The world’s largest glacier is 435km (270 miles) long and more than 96 km (60 miles) wide at its widest point. This glacier is called the Lambert glacier and is found in Antarctica.
5. Glaciers hold approximately 69% of the world’s fresh water.
6. If all land ice melted sea levels would rise 70 meters (230 feet).
7. There are two main types: Alpine glaciers and Continental glaciers. Alpine glaciers flow downward from mountaintops and through valleys. Continental glaciers form large horizontal sheets, aren’t affected by topography including mountains, and tend to flatten anything in their path.
8. Glaciers can be found on every continent, except Australia. While most are situated near the Earth’s poles, in Antarctica and near Greenland, many can be found close to the equator, including Mexico.
9. Glacier ice crystals can grow to be as large as baseballs.
10. Some glaciers appear blue when they become very dense. With years of compression, tiny air pockets between ice crystals get forced out. The ice can absorb all other colours in the spectrum, such as red and yellow light, and reflects blue light. The denser the glacier, the more blue it will appear.
