Summit:
W7O/CE-221
Haystack Butte (W7O/CE-221) is located in the Crooked River National Grassland, which is part of the Ochoco NF. There are some private grazing lands around the base and at the very top that you'll need to avoid, but access to a large activation zone is available via public lands. Note that some online mapping platforms such as CalTopo do not accurately show the public/private land pattern in this area.
