Yellow Jacket Bench is located in the Umatilla National Forest. It can be a drive up summit, or there are places off the final access road NF-40 that you can pull off so you can make the final ascent on foot. It is 30 miles from Walla Walla community college.
Both myself and KJ7IEG made separate attempts at Pikes Peak Bench. This SOTA summit is outside of the Umatilla Forest boundary. I attempted to access it from the Umatilla Forest via NF-6511 from the East and ran into closed access roads, fencing and No Tresspassing signage. KJ7IEG attempted it from the SW from Mormon Grade Rd and encountered same. The area is adjacent to high ATV and hunting traffic so we suspect that the private land owners got fed up with things.
I activated my first SOTA summit here. Nice views and plenty of tall trees for your wire antenna. Parking is great. Plenty of room along with several picnic tables. Restroom facilities were available and clean.
Highly recommend for your first SOTA Summit.

Lone Butte is a "small" hill in the Gifford Pinchot National Forest. It is easily accessible from the Columbia River Gorge via Wind River and NF30, or from I-5 up the Lewis River Hwy to Northwoods and then NF90/Curly Creek Rd. (which connectes to NF30). There is a large area for parking where road 401 cuts to the West. If you aren't particular about your vehicles paint, the road is driveable to an old rock quarry at the west end of Lone Butte, there are some ruts a short way into the road, but they are easy to straddle and most any vehicle could make it past.
