“A down-n-up that follows the pipeline and then a tributary.”
— Jon Sundquist
This is a fun and challenging singletrack that is down then up either way you do it.
Described here, the trail starts at the orange trail at intersection 43. It crosses the Original Trail from the lower lot and then starts descending along the park boundary through a nice flowy and narrow singletrack.
As it loses elevation, the trail gets wetter as expected, although it dries out well as summer wears on. After losing enough elevation, it goes left and crosses each of the two pipelines.
What goes down must go up. The trail starts climbing, following a creek. The steepest (and somewhat eroded) section is at the bottom, and it gradually levels off as it nears the top.
The trail ends back at the orange trail between intersections 40 and 41.
