      Nice and powdery, will be better with rain, but still one of the best downhills in SoCal

      Loose, dusty, and very worn. Not a fun downhill unless you know what you’re doing.

       Perfection, traction is all time right now. Gritty dirt doesn’t get too slippery on the rocks

       Definitely only a trail for advanced riders. There are some huge slabby rock obstacle course drop offs that are not for everyone.

       Agree with below comment, this trail is a step above the adjacent black diamonds. scout the blind rollers first if you’re not a high confidence rider
