[3] Weather fronts originating in the Pacific Ocean travel northeast toward the Olympic Mountains.

As fronts approach, they are forced upward by the peaks (orographic lift), causing them to drop their moisture in the form of rain or snow.

As a result, the Olympics experience high precipitation, especially during the winter months in the form of snowfall.

[4] The months July through September offer the most favorable weather for viewing or climbing this peak.

[5] The mountains were sculpted during the Pleistocene era by erosion and glaciers advancing and retreating multiple times.
