I'm not sure where this erosion on the
Sunset Loop Trail is coming from, but I know where it's going: straight into
Palo Seco Creek.
The biggest mess in the watershed is probably
this huge gully above the Sunset Trail, where Castle Park Trail heads steeply
uphill. Here's Kristen inspecting the damage.
Here's a view of the top of the area, from
higher up the slope. The tree stumps are Eucalyptus that were cut after they
were damaged in a freeze many years ago.
The orange fence is on the edge of the West Trail. There are houses just
across the trail; hope that sewer pipe is OK. There's some kind of drain
structure just across the West Trail. It will be interesting to watch it in a
heavy rain.
In addition to the big gully, the land on both sides is slumping and sliding; the whole area affected is maybe two or three acres. We found a few stubby, gnawed oaks on the hillside and a totally goat-browsed elderberry, so any revegetation would need to include protection from the omnivores.
I haven't checked out most of the upper
watershed yet, but here's a pic of some erosion from Chabot entering the storm
drain inlet that crosses under Skyline, into the headwaters of Cinderella
Creek.
