This route is a step up from the Osbourne mt full route. It adds a nice climb up Silver Creek and a challenging traverse of Allen Mt. The turn off from the paved road is easy to miss so check your Trailforks!

Starting to get muddy. The dirt here is loose and wet. Makes for slow climbs but the Osborne downhill is sweet in those conditions

Trail is narrow with many groundhog holes in the tread and bushy in parts on the way to Allen Mt. The climb is getting unrideable due to sandy moto ruts but that portion is fairly short. The west and north branches are in great shape and very rideable. Not a bad adventure ride but I wouldn't seek it out. The little lake at the end looked pretty swimmable but I was there on a cold day.
