Figure 15. Change in erosion pin exposure at transects of South Fork Campbell Creek near Anchorage, Alaska, between July 1999 and October 2000. [All pins were installed on July 28, 1999. Pins are designated by transect (first three digits); by side of channel (L, left; R, right); and by position on bank (2, lowermost pin where more than one pin is present).
