Logan Glacier is a beautiful ice formation located in Glacier National Park. This park is in the U.S. state of Montana. The glacier sits in a bowl-shaped area called a cirque. It is found to the northeast of Mount Logan.
Logan Glacier is just east of the Continental Divide. It is also northwest of another ice formation called Red Eagle Glacier. In 2005, Logan Glacier was about 75 acres (0.30 km2) in size. But in 1966, it was much larger, covering almost 125 acres (0.51 km2). This means the glacier shrank by 40 percent in about 40 years! Pictures taken in 1914 and 2009 show how much the glacier has melted away.

What is a Glacier?
A glacier is like a very slow-moving river of ice. It forms when snow falls in one place year after year. This snow does not melt in the summer. Instead, it piles up and gets squeezed. Over time, the weight of the new snow turns the old snow into solid ice.
Glaciers are found in very cold places. You can see them in high mountains or near the Earth's poles. They move very slowly, carving out valleys and shaping the land.
Logan Glacier's Home
Logan Glacier lives in Glacier National Park. This park is famous for its stunning mountains and, of course, its glaciers. The park is located in the northern part of Montana. It shares a border with Canada.
The park is a wild place with tall peaks and deep valleys. It is home to many different plants and animals. The environment here is perfect for glaciers to form and exist.
Where is Logan Glacier?
Logan Glacier is nestled high in the mountains of Glacier National Park. It is found in a special bowl-shaped area. This area is on the northeast side of Mount Logan.
The glacier is also close to the Continental Divide. This is a line that separates rivers flowing to the Atlantic Ocean from those flowing to the Pacific Ocean. Nearby, you can also spot the Red Eagle Glacier.
Why are Glaciers Important?
Glaciers are super important for many reasons. First, they store a lot of fresh water. This water is locked up as ice. When glaciers melt slowly, they provide water for rivers and streams. This water is used by people, plants, and animals.
Glaciers also help scientists learn about Earth's past climate. Ice cores taken from glaciers can show what the air was like thousands of years ago. They are like frozen time capsules!
Logan Glacier is Shrinking!
Sadly, Logan Glacier is getting smaller. This process is called glacier retreat. It means the glacier is melting faster than new snow can build it up. In 1966, Logan Glacier was about 125 acres (0.51 km2). By 2005, it had shrunk to only 75 acres (0.30 km2). That's a big change in just a few decades!
Pictures from 1914 and 2009 clearly show this shrinking. The glacier looks much smaller in the more recent photos. Scientists believe this rapid melting is happening because of warmer temperatures around the world.
What Does Glacier Retreat Mean?
When glaciers like Logan Glacier shrink, it can cause problems. Less meltwater means less water for rivers and lakes. This can affect plants and animals that depend on that water. It can also impact people who use the water for drinking or farming.
If glaciers keep shrinking, places like Glacier National Park might not have many glaciers left. This would change the park's landscape and its name! It's a reminder of how important it is to protect our planet.
