Denny Mountain

Denny Mountain is a summit in King County with steep slopes and a rocky peak that rises prominently above the surrounding landscape. The northeastern face features a ski area that serves both winter sports enthusiasts and hikers in other seasons.

The peak received its name from Arthur Denny, a pioneer instrumental in establishing the Snoqualmie Pass Road during the region's early development. This route later evolved into part of the modern Interstate 90 highway system that connects communities across the state.

The mountain's name honors Arthur Denny, a pioneer whose impact on regional development remains visible today through local landmarks and historical records. This connection helps visitors understand the human stories tied to the landscape they are exploring.

The best time to visit is during spring when snow melts or in early fall when conditions are most favorable for accessing the slopes and trails. Good footwear and physical fitness are recommended since the terrain is steep and rocky in many areas.

Elevation readings for this peak have changed over the years as surveying technology has improved, reflecting how our understanding of mountain heights keeps evolving. These variations show the difference between older maps and newer satellite measurements.
