See Picture #2 to see the same location in 2002 to see a reduction in sediment transport. Photo provided courtesy of Craig Bell. 3/30/95

Notice that there is much less sediment deposited and coarser material now in the channel and on the terraces. This indicates a decreased sediment supply from Olsen Gulch compared to the 1994-1995 era. Photo by Pat Higgins.

See Picture #2 to see the proximity of a road to the top of the feature. Photo provided by Pat Higgins.

Note the road through the trees at the top of the slide. If the road channeled water onto the top of this feature, it could play a role in re-activating the slide.

Back pressure from the mainstem Garcia at flood helps to create back pressure so that sediment settles in a delta. See Pictures #6 (2000) and #7 (2003) to see how this deposit has changed.

This indicates a decreased supply from the North Fork. Photo provided courtesy of Pat Higgins.
