Mount Bradley is a tall mountain on Douglas Island in Alaska. It stands about 3,337 feet (1,017 meters) high. This makes it the third-tallest peak on Douglas Island! You can find it about 4 miles (6 km) south of Juneau. The land around the mountain is part of the Tongass National Forest.
Even though it's not the highest mountain in the world, Mount Bradley rises very steeply from the water. It goes from sea level at Gastineau Channel to its peak in only about two miles. Its closest taller neighbor is Mount Ben Stewart, which is about 5.6 miles (9 km) to the northwest.

The Story Behind Mount Bradley's Name
When this mountain was first named by the U.S. Geological Survey in 1904, it was called "Jumbo Mountain." This name probably came from the Jumbo Mine, which was located at the bottom of the mountain. Some people still call it Mount Jumbo today!
The mountain was officially renamed Mount Bradley in 1939. This was done to honor Frederick Worthen Bradley (1863–1933). He was a very famous mining engineer from around the world.
Who Was Frederick W. Bradley?
Frederick Bradley was a very important person in the mining world. He was the president of the American Institute of Mining, Metallurgical, and Petroleum Engineers. In 1931, he won a special award called the Saunder Gold Medal for his amazing work in mining.
He helped a lot with developing the gold mines in the Gastineau Channel area. This included the famous Treadwell gold mine and the Alaska Juneau Mine. He also helped the towns of Juneau and Douglas grow. The U.S. Board on Geographic Names officially adopted the name Mount Bradley in 1939.
Weather and Climate at Mount Bradley
Mount Bradley has a subarctic climate. This means it has cold, snowy winters and mild summers. Weather systems from the Gulf of Alaska hit the Coast Mountains. This forces the air upwards, causing a lot of rain and snow to fall on the mountain. This process is called orographic lift.
Temperatures can drop very low, sometimes below −4 °F (−20 °C). With the wind, it can feel even colder, below −22 °F (−30 °C)! This cold climate helps support the Juneau Icefield, which is a large area of ice and glaciers to the northeast of the mountain. If you want to visit or climb Mount Bradley, the best time is usually July. The weather is most pleasant then.
