Mount Dana is a 6,213 feet (1,894 m) mountain summit in Jefferson County of Washington state.

[5] Precipitation runoff from Mount Dana drains into the Elwha River, thence into the Strait of Juan de Fuca.

Set in the north-west portion of the Olympic Mountains, Mount Dana is located in the marine west coast climate zone of western North America.

[6] Most weather fronts originate in the Pacific Ocean, and travel northeast toward the Olympic Mountains.

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