"[6][7] Following Orion's death in 1916, Denny's widow Helen willed Klahanie to the city of Seattle to become a public park named in memory of her husband.

[8][9] The city of Kirkland began managing the park in 2013, following its annexation of the Finn Hill neighborhood.

[1] The park features an unusual quantity of trees over 150 feet tall, including grand firs, black cottonwoods, western hemlock, and cedars.

Many Douglas firs stand over 200 feet tall, and are among the tallest trees in the Seattle area.

[8][9][12] The park is one of four designated, protected bald eagle nesting areas in Kirkland, all on the Lake Washington shoreline.
