Index mighty Index!  Has a reputation for being intimidating.  Steep granite cracks and sport climbs.  Not a huge amount of stuff for the sub 5.9 leader.  About 1.5 hours from Seattle.  Approach hikes 5-30 minutes.  West of the crest; i.e. wetter.
 

Directions:  Take I-5 to 520 East, then 405 North, then 522 East to Monroe, then Hwy 2 east.  Turn left at Index Cafe (Just after crossing North over the Skykomish River. If you come to the town of Baring you've gone too far). Follow river a mile or so then go left across big bridge into Index.  Travel slowly through town, turn left at the T (Bush House), cross the RR tracks (might want to park here for some climbs, see overview map) then keep heading south (straight, left, right).  Travel down the road about a 1/2 mile.  Just after a huge pullout on the left (river side) watch for an entrance to a dirt n' gravel parking lot on the right. Park there. If the road starts paralleling a RR track, you've gone too far.

guidebooks
Cummins guide is mostly online, and you can buy the real thing cheap at the general store in Index (see overview map).
Cramer, "Sky Valley Rock Climbs", is more up-to-date and very good, and the Smoot's "Washington Rock" will get you by too.
