Forbidden Peak rises to 8,815 ft in Pacific-Ranges within the Cascade Range range.

With an elevation of 8,816 feet (2,687 meters), it is a popular destination for mountaineers seeking a challenging climb. The peak is known for its rugged and steep terrain, requiring technical climbing skills to reach the summit.

During the winter season, the snowpack on Forbidden Peak can vary greatly. The Pacific Ranges receive significant snowfall, and the mountain is often blanketed in deep snow. Snowpack depths can range from several feet to over ten feet, creating hazardous conditions for climbers. It is crucial for mountaineers to assess snow stability and avalanche risks before attempting an ascent.

Forbidden Peak is surrounded by several creeks and rivers that receive runoff from its melting snow. The most notable waterway is the Boston Glacier, which is located on the northern slopes of the mountain. This glacier feeds into the Boston Creek, contributing to its flow during the summer months. Other creeks and rivers, such as Forbidden Creek and Marblemount Creek, also receive runoff from the mountain's snowpack.

As for the history and lore, Forbidden Peak's name originates from its daring and challenging nature. It was named by early explorers who believed the peak to be nearly impossible to climb. However, it gained popularity among adventurous mountaineers, and its summit has been conquered by many since then. Though no specific legends or lore are widely associated with Forbidden Peak, its formidable reputation continues to captivate climbers and inspire them to conquer its slopes.

Push-notification alerts (snow / flow / buoy / ski) are managed in the iOS app because they require APNs + device tokens; the webapp has no equivalent surface, so the right thing to do is point users at the App Store.
