This trail goes straight down an expert ski run (and long ago the lift line for chair 9). It drops straight down the fall line and is so steep that it's difficult to even walk. It's badly eroding and not at all sustainable.
It should only be attempted by experts with downhill bikes and full body armor. Expect mandatory drops where stopping is not an option.
You do make some swithcbacks after a while, but even those are quite hard. The bottom third is more rideable by mortals, and is a mildly rooty singletrack hugging parts of Big Mamba.
