I did some more work on the Serpentine Climb Reroute today.
Started work on the switchback turn. The AM was devoted to gathering and placing rocks for the wall on the downhill leg. Because the upper leg passes over a couple of large rocks bigger than I can move, I am not able to get fill by digging the uphill leg into the hillside.
In the afternoon, I got 6 contractor size wheelbarrow loads of dirt by deberming the existing trail uphill from the turn and adding a wide, shallow dip for water control. The dirt is a good start on filling the downhill leg of the turn.
There's a lot more dirt needed, but the turn can be ridden as is.
(The pictures are out of order. The bottom picture shows the lower leg of the turn before any fill was added, the top on is the "after" shot.)
