SOS is a fun chute off of Lost Prospector. A few corners have roots and rocks that make this a black diamond rating. It is a tight bobsled style trail that has a tendency to get overgrown. If you need to access the Rail Trail from higher areas, this is a great option. The trail is well marked with a sign.
