Quite the name for a stream, probably gets it's name from the gurgling roar of the stream off of Canaan Mountain and the way Great Laurel dim down the sound to make it sound a bit like an engine.

A surprisingly nice peddle up from the North Fork Red Run on Canaan Loop, heading up Canaan Mountain to Table Rock.

While I don't recommend carrying a mountain bike up the Limerock Trail as there isn't a lot of good places to ride up that way, and it's a long 4½  miles hauling over a few waterfalls and cliff edges, it can be done. Better just done walking, and enjoying the scenery.
