Creeks disrupt development and make room for parks which is where we find trails and bridges.
We make a page for a creek when we encounter it more than once or twice as we wander. We then focus our attention to additional access points we may have missed.
We focus on westside creeks: north of Tualatin, west of Willamette, south of Skyline.
Beaverton and Fanno Creeks dominate this area with one heading west, the other south.
