Signal Peak is a 12.7 mile Priusable drive up with some pot holes that are easily navigated. It does not need a Weyerhaeuser permit for access. Although you traverse through Weyerhaeuser land, the road you take is designed as a “Public Access Corridor” to the state forest where the Signal Peak summit is located.
In the past (and for a prior writeup), this summit was off-limits as part of a leased club parcel. Maybe Weyerhaueser couldn't find any clubs to lease it, or just changed their mind about how they wanted to manage the land, but it has ceased as a lease and become open to public access. It's a bit of a drive for one point, but a unique nonetheless.
Pig Iron Mountain is a drive up good gravel forest road plus a half mile light-to-moderate bushwhack through rhododenrons. As such it's reasonably easy enough to reach, though no view at the top to particularly recommend it compared to other local peaks.
We found no pigs, iron or pig iron. Totally misleading peak name. There was just a bunch of bushes. Maybe they are pretty assuming they flower in the spring time. Dunno. YMMV.
During the 2023 W7O SOTA Campout, we had the opportunity to activate Trap Mt.
This is an easy drive, though there are spots where the manzanita closes in on the roadway. Your vehicle's paint may not like it much. Otherwise, it has good gravel all the way to the trailhead. Take a left from Hwy 138 West onto NF-900, then a right onto Big Camas Rd (NF-3701). Take another left onto NF-3704 and follow that around and turn left on NF-230 and yet another left onto NF-250 and a final left on to NF-290. Google Maps was right this time!
Long Mountain is on the Weyerhaeuser recreational permit area for Columbia - Washington Counties. It was previously activated via a 12 mile hike, but this is not the only route. As it turns out, there's a straightforward access trail via BLM land to the southeast of the peak, which only requires about 1.5 miles of hiking each way.
Frog Lake Buttes is a popular SOTA destination that was moved slightly from its old high point in March of 2023. The old summit plays host to a cell tower and is accessible via both road and trail.
The summit of Rock Point is a steep short climb up from either the Paradise Trail #124 or FR-6401. Both the forest road and summit are shaded and would be a good choice for a hot sunny day. In good weather, it could be combined with other peaks nearby W7W/LC-059 Timbered Peak and W7W/LC-064 Sister Rocks. If doing multiple peaks, I would do this one last as it is the most shaded route of the three due to recent fires.
NC-130 is another of the recently added peaks during the 2023 ARM update, currently the last of the Oregon NCs. If that's a goalpost you're looking to achieve, or you're feeling particularly completionist, or you just like a good bushwhack, proceed on. Otherwise, maybe skip this one. It's on public land, and consists of a 6 mile forest road drive, combined with a 1.5 mile hike and bushwhack. This peak is easiy paired with NC-099.
Pilot Knob is a quiet peak inside the boundary of the Gifford Pinchot National Forest, and a stone's throw away from the Pacific Crest Trail. The approach is just short of 2 miles one-way, with some travel on an old trail and some bushwhacking.
The drive is about 1 hour and 15 to 30 minutes from somewhere in Portland. The hike is about 2 miles one-way with 1300' elevation gain and took about 1.5 hours to complete in the dry season.
Maidenhead Mtn (W7W Summit 1930) is accessible with a 1.5 mile (800 ft vertical) hike up an abandoned Forest Service Road bed. The road bed is overgrown with trees that look around 8 years old. There is a trail that is established for about 50% of the way. The second half of the route has a significant amount of blowdown and really slows you.
