Same symbolism as my other Washington State entry, but with the triangles narrowed and the shade of blue darkened.

The blue, green, and pale gold represent the blue of the sea, the verdancy of the forests, and the pale gold of wheat (as a representative for agriculture).

The five overlapping triangles represent the five largest peaks of the Washington section of the Cascades. They also form the stylized shape of a coniferous tree.

The entire flag can additionally be interpreted as a heavily-stylized map of the state.
