Click on image to enlarge (59K). Click here to display a larger version (180K).View of Anderson Creek looking downstream from the Highway 253 Bridge. This confined reach of the creek has a large cobble and boulder bed. Young alders line the immediate stream bank and grasses cover the back terrace. The stream is naturally subject to warming in the oak woodlands associated with mélange terrain but disturbed sites are even more so. Photo by Pat Higgins, 6/12/02.

The Anderson Creek basin is in Central Belt Franciscan mélange and is naturally prone to erosion. The road location (linear feature at top of photo) may have accelerated erosional process at this location. This area may also have a history of grazing. Photo by Pat Higgins, 6/12/02.

In the foreground Baccharis (coyote brush) has colonized the disturbed area next to the highway. Up hill of the oaks is bare soil with gully erosion. Note the road bench at the toe of the disturbed slope. Photo by Pat Higgins, 6/12/02.

The flat area at the toe of the feature is an old road which was cut across this sheared material and lead to soil loss through sheet and gully erosion. See the next photo for the area below this focus just above the creek itself. Photo by Pat Higgins, 6/12/02.
