I use the 2008 edition DeLorme Oregon atlas & gazetteer. you need to go up on top of the Abert Rim. The Paiutes had hundreds of small camps up there. That would be the west side of ***back rd. Look on your map and see if you can find Mule Lake....it is right on the edge of the rim. Rabbit creek rd will take you up there. There are no rd numbers or signs. Its all about reading your map. 4wheel drive not needed but advised, I take my jeep up there. Been hunting the top of the rim for about 6 years and could easily spend another 6 to cover it all. you can camp anywhere up there. Spectacular views from the Rim. Petroglyphs all over in the rim rock. Mule Lake is one of my favorite places on the rim. A bit of an adventure getting up there, but well worth it! Also good hunting along rabbit creek right below the rim rock.
