Lagunitas Creek near Point Reyes Station, December 5, 1983
Photograph taken from bridge leading to the California Cooperative Creamery off Petaluma - Pt. Reyes road. Looking downstream; lack of point bar allows plants to grow down into the creek, thus roughness, represented by the point bar upstream, is represented downstream by the trees.
Walker Creek, December 5, 1983
Photograph taken about 1.5 miles from mouth, 100m from road bridge looking downstream. Point bar is composed of silt and sand with some gravels at the extreme upper end of the bar. The floodplain, from which the picture was taken, is extreme in extent reaching 100m wide. Upstream from where the photograph was taken, trees are growing on the floodplain where it meets the point bar.
Novato Creek at Novato, December 5, 1983
Photograph taken looking downstream from gage station. Creek is very natural looking considering the extent of urbanization that has occurred in this area. The gravels contained in the bars seem to be of a uniform size, and the stream seems to be in equilibrium with no erosion or aggradation occurring at site. At the station there is evidence of fill from the parking lot which has covered the natural slope of the creek.

Arroyo Corte Madera del Presidio at Mill Valley, December 7, 1983
Photograph taken from the Lagoma street bridge. The bridge from which figure 14 was taken can be seen in the distance. Here existed the only point bar in the area such as it was. The point bar is not very well defined and contains gravels of various sizes, including chunks of asphalt.
Corte Madera Creek at Ross, December 7, 1983
Photograph taken from the lowest extent of the point bar across from the gage station. Here the bar is composed of fine gravels and sand. This bar is one of the larger bars seen for a creek of this size, possibly due to the greater rainfall experienced by the area. Photograph taken looking upstream.
Corte Madera Creek at Ross, December 7, 1983
This photograph was taken 45m upstream from Figure 16 showing the upper extent of the point bar. Here medium size gravels predominate with no sand present on the surface. Photograph taken looking downstream.

Under the bridge there is a point bar on the opposite side of the creek composed of silty sand with some small pebbles. Photograph taken looking downstream.
