Chris, Doug, and I rerouted the NE part of the southhill yesterday. It is probably half a mile of mostly downhill grade. We looked for where to place the switchbacks and used a 6' level to make sure we had grade reversals connecting the switchbacks in order to shed water off the trail. Then we rode the flags and adjusted them for flow.
When you see several trails cut, please only ride the one marked by orange flags.
Also, a couple corners were rerouted down to the iceplex for better flow.
Several will be riding tranquility tonight at 6.
Here are before/after pics of an armored water crossing.
This should only be ridden when dry but the cement blocks will prevent the water from gouging the trail more.
