Ladder Creek Glacier is a cool natural ice formation found in North Cascades National Park. This park is located in the state of Washington, in the U.S.. It's actually a smaller part, or "tongue," of a much bigger ice area called Neve Glacier.
Like many glaciers around the world, Ladder Creek Glacier has been changing size. Between 1950 and 1979, it actually grew a little, adding about 105 m (344 ft) of ice. But from 1979 to 2006, it lost more than it gained, shrinking by about 190 m (620 ft). This glacier flows downhill, starting from about 7,800 ft (2,400 m) high and ending around 6,000 ft (1,800 m).

What is a Glacier?
A glacier is like a giant, slow-moving river made of ice. It forms when snow piles up over many years. This snow gets packed down so tightly that it turns into ice. Gravity then slowly pulls this huge mass of ice downhill.
Glaciers can be found in very cold places. This includes high mountains or near the Earth's poles. They are an important part of our planet's water cycle.
How Glaciers Form
Glaciers start as snowflakes falling on the ground. If the temperature stays cold enough, the snow doesn't melt completely in summer. More snow falls on top of the old snow each year.
As new snow piles up, it presses down on the layers below. This pressure squeezes the air out of the snow. The snow crystals then change, becoming denser and turning into ice. This process can take many decades or even centuries.
Where is Ladder Creek Glacier Located?
Ladder Creek Glacier is nestled in the beautiful North Cascades National Park. This park is known for its rugged mountains and many glaciers. It's in Whatcom County, Washington, which is in the northwestern part of Washington state.
The North Cascades are often called the "American Alps." This is because they have sharp, jagged peaks and deep valleys. The park is a wild place with lots of forests, rivers, and wildlife.
The North Cascades Environment
The area around Ladder Creek Glacier is very mountainous. It gets a lot of snow and rain, which helps glaciers form. The high elevation means temperatures stay cold enough for ice to survive.
This region is also home to many different plants and animals. You might find bears, deer, and various birds living here. The melting ice from glaciers feeds streams and rivers. These waterways are important for the local ecosystem.
Why Do Glaciers Change Size?
Glaciers are always moving and changing. They can grow bigger (advance) or shrink smaller (retreat). These changes are a natural part of a glacier's life. However, human activities can also affect them.
When a glacier gets more snow than it melts, it grows. When it melts faster than new snow can build up, it shrinks. Ladder Creek Glacier has shown both of these changes over time.
Factors Affecting Glaciers
Many things can cause a glacier to change size. One big factor is temperature. Warmer temperatures cause more ice to melt. Less snowfall can also make a glacier shrink.
Another factor is how much snow falls each winter. Heavy snow years can help a glacier grow. Long periods of warmer weather or less snow can make it retreat. Scientists study these changes to understand our planet's climate.
The Importance of Glaciers
Glaciers are more than just big chunks of ice. They are important for many reasons. They store a lot of the world's fresh water. When they melt slowly, they provide water for rivers and streams. This water is used by people for drinking and farming.
They also help scientists understand Earth's past climate. Ice cores taken from glaciers can show what the atmosphere was like thousands of years ago. This helps us predict future climate changes.
