         Sediment: Matthews Erosion Rates from Harvest Areas LNF 1921-2000 |

   Caption:  This chart shows estimated surface erosion volumes from skid trails in harvest areas as computed by Matthews and Associates (2001).  The period of 1921-1936 resulted in a large volume of surface erosion from extensive harvesting in the basin (click on Picture to see harvest areas by period).  Estimates are generated from CDF data and aerial photographs.  See Info Links for more background information and links to references.
