Rho Ridge Route South of Cachebox Meadows

I'm looking at the map and planning a Rho Ridge traverse. I'm confident from the trail descriptions provided on this site that I should be OK for all trail segments north of Cachebox Meadow but I'm uncertain about the route going south to Collawash Mtn and the intersection with the #3360 Bald Butte trail. Is there trail south of Cachebox Meadow to Collawash Mtn. and should I expect to link up with the #3360 without much trouble?

Thanks,

--Paul
