Located about 50 miles SE of Bend off of Hwy 20 is Frederick Butte (W7O/CE-130).  This is a good summit to combine with Hampton Butte (W7O/CE-074) if you’re visiting this part of central Oregon.  Frederick has fairly easy BLM road access to reach the base of the butte - via Frederick Butte Road, 10mi drive south of Hwy 20 - but requires a mile climb bushwhacking up to the summit.  The map below shows the route I took, which I recommend.  There are other more direct routes, but know that near the top it gets very rocky and bushy.  I had good Verizon cell and data service on the summit…
