Rainfall from the past week has increased soil moisture to high levels across western Washington. Additional rainfall of around 2-6 inches is expected early this week. This amount of rain will put extra pressure on soil instability, leading to an increased threat of landslides and debris flows, especially from recent burned areas. This rain event could act as a trigger for new landslides. Areas most susceptible to landslides debris flows under these conditions are steep coastal bluffs, other steep hillsides or road cuts, and recent burned areas. A diminishing threat of landslides and debris flows will continue for several days after the rain ends.

Summary
With an elevation of approximately 4,000 feet, it provides breathtaking panoramic views of the surrounding area. The trailhead starts at an elevation of 1,160 feet and ascends relentlessly through dense forest, making it a challenging but rewarding hike. The peak itself is rocky and treeless, providing hikers with unobstructed vistas.
During the winter season, Mailbox Peak receives a significant amount of snowfall due to its higher elevation. The snowpack range can vary depending on weather conditions, but it typically accumulates from November through April, transforming the landscape into a winter wonderland. This makes it an ideal destination for snowshoeing and winter mountaineering, offering a different experience from the summer months.
Several creeks and rivers in the surrounding area receive runoff from Mailbox Peak. One notable creek is the Pratt River, which originates from the mountain and flows into the South Fork Snoqualmie River. This runoff contributes to the pristine water sources in the region, supporting the diverse flora and fauna that thrive in these ecosystems.
The name "Mailbox Peak" is derived from a fascinating legend. In the past, hikers used to leave mementos or messages for others in a mailbox at the summit. It became a tradition for climbers to carry a memento or leave a personal note for future hikers. Although the mailbox has been removed due to excessive weight and damage, the name has stuck and continues to be associated with this majestic mountain.
