Green Mountain is a mountain in Washington state, U.S. It stands about 4,824 feet (1,470 meters) tall. This mountain is found in King County, on the western side of the Cascade Range. It's part of the Mount Baker-Snoqualmie National Forest.
Green Mountain is special because it rises very steeply from the land around it. Its closest neighbor is Mount Teneriffe, which is about 1.18 miles (1.90 km) away. The water that falls on Green Mountain flows into streams that lead to the Snoqualmie River.
Weather at Green Mountain
Green Mountain has a "marine west coast" climate. This means it gets a lot of weather from the Pacific Ocean. Most weather systems travel from the ocean towards the Cascade Range.
When these weather systems hit the tall Cascade Mountains, they are forced to rise. As the air goes higher, it cools down and drops its moisture. This causes a lot of rain or snow to fall on the western side of the Cascades. This process is called orographic lift.
Because of this, the area around Green Mountain gets a lot of rain and snow, especially in winter. Winters are usually cloudy. However, during summer, high pressure systems over the Pacific Ocean often bring clear skies. The snow here tends to be wet and heavy. This can sometimes create a risk of avalanches.
How Green Mountain Was Formed
The Cascade Range, where Green Mountain is located, started forming millions of years ago. This happened during a time called the late Eocene Epoch.
Later, during the Pleistocene period, which was over two million years ago, huge sheets of ice called glaciers moved across the land. These glaciers scraped and shaped the landscape. They left behind lots of rock and dirt.
The last glaciers in this area started to melt and move away about 14,000 years ago. By 10,000 years ago, they had moved north of the Canada–US border. The valleys you see today, which often have a U-shape, were carved out by these glaciers.
The combination of the land pushing up (called uplift) and cracks in the Earth's crust (called faulting), along with the action of glaciers, created the tall peaks and deep valleys of the Cascade Range.
