Miller Peak is a large commercial communications site. Given that, the road accessible to the public is narrow, brushy and with few places to pass on coming vehicles. The road can become a bit crowded in later summer if a huckleberry crop along the road entices pickers.
This is an urban park activation about thirty minutes from downtown Portland. No GPS device needed as Google maps provides good driving directions. Though you can pull off a 2M sidelwalk activation near the summit (which is on private property), a more pleasant place to operate from is Skyline Ridge Park (45.3905, -122.6634), about a half mile south. RF noise levels are high, so while a nice spot for an activation, don't expect big things on the HF bands.
Another Bald Mountain on my list. I swear we need a S2S Party just for summits with "Bald" in the name! Easy drive to summit but not really any view, just a nice park-like area. Beautifully timbered, relatively flat summit top. Easy to set up. I had zero service here. Might of had texting if I set up on the west edge but I almost always go for the east side. I had trouble hitting RBN and being found. 40m rescued me and I was able to get several QSOs once found.
Olson is a near drive to summit. Find a good spot to park on the side of the road and find a good opening in the timber and brush to get to the top/AZ. The road may even be in the AZ but I went a bit higher. Ample area and trees to set up and logs to sit on. We took the Butte Falls Hwy to Cobleigh Rd to Medco B Rd. All gravel roads were well maintained.
TL;DR - Peak 3534 is a twenty to thirty minute drive from South Saddle Mountain (W7O/NC-002) over logging roads. You pass South Saddle to get to 3534 so a two summit, four point day is easy. 4WD, good directions, and GPS are really handy. Once you park, the short hike up is steep but no worries, there's a longer, gentler path, too. The summit has no views, a small open space, trees, good APRS signals, and is RF quiet. Not a summit for hanging out nor the best place for HF antennas but easy to activate with 2M FM.
An opportunity for a one-day, three summits activation. A good US Forest Service road system gets one close enough to activate three summits easily in one day, rare in Western Montana. Babcock Mountain is forested summit. The other two summits, Golden Mountain (W7M/GA-141) and Burnt Mountain (W7M/GA-145) are open summits and accessible via short hikes from the same US Forest Service road system. Trees are available for attaching wire ante
Peak 2020 is relatively easy-to-access summit near the city of Tillamook on BLM land. It's nearly or fully drive up depending on your transport. From the look of the area, it's probably a known go-to spot for offroaders and hunters in the local forest who want a good view and a place for an evening fire.
A 'sorta' near drive-up in the Gifford Pinchot National Forest north of Carson. You can drive within a mile of this unremarkable peak and likely have a nice quiet time playing radio.
Cinnabar Point is currently a mature lodgepole forest on a rolling summit. In the 1980s the summit sported a dilapidated pole tower structure that may have been used as a lookout, but has since fallen and rotted. It is an easy mountain bike ride up a permanently closed road and then a short climbing trail to an off-trail gradual assent to the summit.
Bunker Hill is an unremarkable summit that can be reached, cautiously, with a 4WD vehicle. After you leave the highway, the way up has a number of branch points; GPS or a map will be handy. When you get to the yellow gate, take down your antennas and be carefree about your paint getting scratched, otherwise, park here and hike up. It is roughly a 300' climb over half a mile.
