High speed descents, punchy uphill climbs, and, unlike most trails at Henry's Ridge, there are a few flagged surfaces to launch off of (if you want to). There is a cleared section during one of the climbs with a great view of Mount Rainier (on a clear day).

Access Info

Starts from the end of Iron Brigade, which you can enter from Water Tower Park in the Maple Ridge neighborhood.

      Not sure why this is considered a black trail.

      One tree down from last night’s high winds and some debris. Trail very dry.

      Fun trail, well maintained. More technical than others, but a great flow.
