Browns Mountain, west of Sunriver, despite being pretty close to a paved road, was a tough bushwack for Roland-K7FOP and I, as we pursued several "shortcuts." So we recommend walking about 2.4 miles on forest roads, and a final steep ascent of about 1/10 mile. Total is about 900 feet of gain. If there's a better way to get to the AZ, please write up an updated trip report.
Bishop Mountain is an extinct volcanic vent on the rim of the Island Park Caldera. At the summit there is a fire lookout that is one of the few remaining towers in the Targhee National Forest. The 72-ft tower was constructed in 1937. Now on standby status, the tower saw extensive service during the Yellowstone Fires of 1988. The summit also has a couple of picnic tables, a cabin that is available for rent through the Forest Service and a fire pit.
Ochocco Mountains High Point could be considered a drive-up summit...for some vehicles. Although most of the way is paved, your low clearance passenger vehicle will have problems with the road in places where you can't turn around. A quarter mile of walking to the summit is recommended - it's a neat spot.
About 30 miles east of Prineville on Highway 26, turn north on Forest Road 27. This may be described as Grant Springs Road, or Summit Road, depending on your resource. This is near milepost 49.
Chase Mountain is in the Blue Mountains of southeastern Washington near the town of Dayton. There is no trail to the summit, but you can drive right into the activation zone. Park at the bottom of forest service road 6437 for a 2.2 mile walk or drive up to the top and walk out and back in as I did. There are a few places at the top to pull your vehicle off the road.
Grivets is a simple "SOTA-car" (drive-up) summit about 30km south of Grenoble, France. There's nothing remarkable about this one-pointer, but it could be a quick activation stop along the A51.
I've been up on Whale Head a few times and it looks like it's time to write up a trip report! This has been a "near drive-up" summit, however with the growth of slide alder into the road you may park and walk earlier that the gate.
Summary: West Onion Peak is a great activation if you don't mind the 13 mile round trip hike.
I just wanted to post a quick update on W7O/NC-044 the previous write up is still accurate but as I understand some people have found it posted no tresspassing I just wanted to post an update from my recent activation there.
Here's a nice 3 mile snowshoe or cross-country ski in the winter. OR...you may be able to drive within about a half mile in the summer. For a good ski experience, you might want to have at least 3 to 5 feet of snow on the ground - see the depth measure in the first photo below.
The activation zone for Cooper Mountain is a (very) short hike above the dog park at Winkelman Park, 10139 SW 175th Ave, Beaverton, Oregon. There is no AZ access from Cooper Mountain Nature Park to the west and the summit proper is posted "No Trespassing."
