The Toutle River runs for 17 miles in two separate forks, converging into one and finally spilling into the Cowlitz River just a few miles north of Castle Rock.

At this point on the boundary trail, you can see that ash still pervades its banks, though the inevitable spread of flora and fauna will soon build up enough topsoil to revitalize the area.

I had never seen a clearer, and more definitive view of the tributary, even in photographs. It is astounding how much of the mountain's topography, geology and habitat are on clear display on this trail. And on a beautiful day, you can't really find a more beautiful hike in the southwestern portion of the state.
