Plaza Creek Trail:
http://www.trailadvocate.org/trails/506
The area was impacted quite heavily by fires in the 20s, and the trails in the area weren't built to the greatest standards. Therefore, it's hard to find a steady route in that country. I've followed the Plaza Trail a couple miles maybe, it fades in and out, and is EXTREMELY steep. Right up the side of the mountain, no switchbacks and tons of brush. It's a fun area to explore in mainly second growth forest, but make sure you know routefinding, it's easy to get lost. The tread is very faint, I don't think this trail ever got much use. Also very crumbly dirt/geolgy. It is believed that a lot of the Roaring River trails were built for reseeding efforts in the 30s after the fires, and were abandoned quickly after.
Last I heard, there is still 8' of snow in that area......
