My friends and I have established some cool areas over the years, between the Applegate Illinois Valleys. Most of what we've done have been bolted sport routes on andesite cliffs, some of which require a hike to get to.
The roadside sport routes are around 40 to 45 degree overhung, reminiscent of Cave Rock, and range from mid 11 to 12c. This particular crag (Hangman's Rock) is high on Little Greyback road on the southest edge of the Illinois Valley.
Let me know if you want more beta and I'll try to dig up some images.
Rattlesnake is probly the best area near the valley. It has a high concentration of routes in the 10+ to 11- range. 30 or so of the routes are really good, and there are another 50 or so scrapier ones. The rock is typical Oregon Tuft, not as good at Smith, but some is really good and some is terrible, bring a helmet for the belayer. Most routes are sport bolted, and many can be accessed from above for TRing. There are a handfull that take mixed trad gear, but there are few gear only leads. You can follow the shade and stay pretty comfortable on all but the hottest days. The access is hard to find without a map as it follows some logging roads.
Greensprings is probly the next best area. It has about 10 quality routes. It is close to Ashland up HWY 66. It gets full sun so it bakes.
Emigrant lake is full right now so some of the crags base may be covered. It is primarily a short scrapy cliff with blocky routes. It has the most moderate grades for the area and most TR potential. Lots of poison oak.
Castle Crags is 1.5 hour drive if you are moving. The approach hike is about 1.5-2 hrs on a nice trail. It is a fun day out.
