South Fork Mountain can be a drive up. It is somewhat less than a mile from NF-4540 on an unmarked road. The fork off of NF-4540 is at approx. 45.101, -122.249. From here a high clearance vehicle that you don't mind getting scratched is required. The road is quite overgrown and has drainage ditches cut across it at various places. It opens up a bit before you get to the top, so you can park and make your final ascent by foot. I had to drive to the top after activation to turn around. A shorter wheel base vehicle might be able to avoid that.

This summit is a long ridge located between Vernonia, Oregon and Saddle Mountain. Here are the directions to get there.

Black Butte may be a drive up. It is a six point former lookout in Grant County. Don't get it confused with the Black Butte near Sisters. 

Nipple Butte is a peak in the Malheur National Forest.

Vinegar Hill is located in Oregon above the Middle Fork of the John Day River near Bates State Park. The veiws from the top are spectacular. It is easy to find as there is a sign from the Middle Fork road pointing to forest road 2010.  It reads 13 miles. The first six of those are good gravel accessible to any car. The next six are rutted and rocky and require a high clearance vehicle. The last mile is available to a 4x4 in late summer or early fall. When we were there on July 1st the road was blocked by snow, so we walked the last mile and 650ft of elevation.
