Grassy Mountain - Bangtail Divide North (IMBA Epic)

The trail is in poor shape after the work that's been done. I gave it another go in the dry and after a few weeks for it to settle. So much unnecessary work took place and it's too bad the focus wasn't on quality fixes for the problem areas. Quick flat chicanes, ineffective drainage work in spots, spots where there's grade reversals every 100ft, diverging around/covering up/removing rocks that made the trail interesting, and worst of all are the weird piles of stuff in the old trail that cause quick off camber detours. Take it easy if you ride it as a loop and didn't see the changes on the way up because some of these changes sneak up and are sketchy at trail speed. It's unfortunate to see resources going into this kind of work and hopefully the forest service will make these kinds of projects more public in the future for input from user groups. It's also unfortunate that someone appears to be deleting these reports that aren't supportive of the work.

Excellent conditions, a few very short sections of mud with a clean path thru. May not last with weather due to change!

Currently the Bangtail trail is being reworked with a machine from the Grassy mountain side up. It has created very soft dirt, Moto and bike traffic could ruin the hard work that is going on over then next few weeks. Please steer clear and ride elsewhere until the work is done and the tread has time to settle. Thank you. reporter

Leaving from stone there was a little mud. From the Top of Stone creek the next section has you battling new tree growth. A hand saw would go a long way. The mud began to be a challenge in the first encounter with Dark woods and was noticeable in the Ninja woods and continued to the top of Grassy. The moto ruts have got to be huge Near Olson. New lumber project later portions has left a lot of brush on and close to the trail. The Grass downhill in the beginning has a lot of pink sized rocks, so go easy.
