Description: This is a small-resolution version for display in articles. (See high res and medium res versions below.)

Tributary creeks, major street intersections, neighborhoods, parks, natural areas, and other landmarks are indicated. The route has been artificially straightened. Each of the panels is oriented differently so that the image fits on a horizontal line.
