Round Mountain is a road hike of about 2 miles one-way and 1000 feet of gain. It's close to Lookout Mountain-W7O/CE-039 so you might consider doing both of those peaks.Note that there are FIVE Round Mountains in Oregon, with one in CE near Lakeview. This is the Round Mountain east of Prineville.

My son and I did this activation. The starting point for our hike was the intersection of FR 5603 and the Pacific Crest Trail. We parked at this location and started walking down the PCT  which was adjacent. We found no trail to the summit so we started bush whacking. It was not too hard. After about an hour, we made the summit. 

Quick notes: I have Google Fi, which uses T-Mobile and Sprint. Cell service is great, if you have a view to the northeast. Otherwise, it dies, and quickly. This was obvious when I was trying to stay in contact with people throughout the hike, leading to cutting in and out throughout the trip. I got it into my head to try a 4-pointer with no activations, and I saw a prime candidate, of only .7 miles with a gain of only a few hundred feet! What a find! Only problem is, there's no trail. Well, that's no problem!

After reading K7EEX's warning about Stimson land, I reviewed the maps and Peakbagger reports, and found that a 2.6-mile trail existed starting right from the edge of US 26, up Shields Road, and staying on Tillamook State Forest land for the majority of the trip. In fact, this summit can be activated without ever stepping foot on Stimson land, as the boundary of their land is just a little higher than the activation region, but Stimson has a permissive access policy for non-motorized, leave-no-trace day use, so read their stipulations and head right up.

Summary: West Onion Peak is a great activation if you don't mind the 13 mile round trip hike.

First time activation of 2011 Good Copy Hill on April 7th.  There is no trail to the summit, but a you can drive within .25 miles, with a 4x4 you don't mind getting scratched up.  It's a narrow dirt road thru sagebrush.  Follow the game trails up to the summit.  Was able to make contacts on 20m & 40m. (SSB)

Summary: On 31MARCH19 I decided to complete the first activation of W7O/NC-072 currently called only '2905' I had briefly attempted this summit for the S2S party on 23MAR19 but found the road covered in snow.  Today however I was able to drive the majority of the way up with the actual hike portion being fairly short but sweet.  I made the mistake of completing the activation during a big CQ competition so the entire 20m band was full of signals but I was still about to get 18 contacts including 3 s2s contacts.

To get to Stacker Butte, Washington, from Interstate 84, take exit 87 at the Dalles and go north across the Columbia River for approximately 3.5 miles to Highway 14.  Note; After taking exit 87 and turning north, there is a McDonalds on the left.  This is the last opportunity for "facilities".  If you don't use them, Stacker butte is very exposed all the way up, and you will be too!  Also, this bridge crossing the Columbia is NOT a toll bridge.  When you get to Highway 14, turn right (east) and go about 0.9 miles to Dalles Mtn Rd and turn left.

Winter activation of a "standard Idaho 2-pointer" (read: barely achievable especially during winter!).  I took advantage of a newly activated holiday at work (President's day) to activate the closest summit to Boise.  I went up the standard "hiking" summer route.  The round trip on foot is 11.5 miles and 3000 ft vertical.  The summer "4x4 drive-up" route is gated closed Nov-April and is currently under a bunch of snow.  

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."
