A short technical rooty downhill from near the start of Mike-o-Rama to the gate near Hwy 109. A lot of side-tracking off-camber singletrack with some steep very technical root sections. Quarter-mile long track with 50-feet of elevation change.

 Thanks Jesse for making some adjustments. It’s still challenging but a bit more rideable. One of these days I’ll make it all the way down.

 I would say it definitely earns it's diamond status. It seemed pretty dangerous to me. Leave it to the pros.

      Not sure why it’s listed as “aka Zipline” - Zipline is a different trail here at Seabrook.

      Hella roots. Fun descent but make sure you and your bike are up for it.

      A lot of fun. Could use some more roots though
