Rode Basalt Ridge from the very top at the intersection of Garland Peak Trail all the way down to the Finner Creek TH via a CCW loop using FS 6210 to Upper Chickamin Tie, Shetipo to Garland Peak.  

First off, If Basalt Ridge top to bottom was cleaned up, which would take some serious chainsaw work and brushing it would be an incredible descent from junction of Garland Peak Trail all the way to Finner Creek TH.  The upper ridgeline, starting at about 7,400' offers over 5,000' of net descending (closer to 6k cumulative after the climb back up Basalt Peak) and has incredible views of the Glacier Peak wilderness with an optional side hike up to Garland Peak for even better views.

Garland Peak TR from Basalt Ridge to Shetipo, while beautiful, is nearly non-existent and an unrideable suffer fest and not recommended, if you want to ride Basalt Ridge from the top do an out and back either via FS 6210 to Basalt Pass and turn right and go up the ridge or via the route described on the site and continue up the ridge from Rock Creek Tie.

From Garland Peak trail to Rock Creek Tie it is quite steep in places with lots of loose rock and some good technical sections and some exposure.  Lots of smaller handlebar grabber trees and a few down trees and the trail is tough to follow in places.  As you get down into the forest there are lots of down trees and some overgrowth.  Closer to Rock Creek Tie it is a steep switchback descent that is really overgrown with huckleberries and other undergrowth and the trail is barely visible in places.  It obviously sees little use.

From Basalt Peak down to Finner Creek TH it is very dusty and dry.  The trail is also getting overgrown and even tough to follow in a few places up in the burnt forest. Lots of down trees, maybe 10-20 on the descent total, not enough to completely ruin the fun but it is a buzzkill.  This trail really needs some chainsaw love or it could be lost completely in the next few years as blowdowns from the fire continue to come down.
