Access is via the Klootchy Creek County Park off of HW26 just 2 miles east of Hwy 101 near Seaside. There's plenty of parking. And a pit toilet.
The summit and access are on Nuveen Natural Capital (private) property, previously Lewis and Clark Timberland. A (free, as of 2025) access permit is required from https://nncpermits.com/ Get the one for NNC_OR_25.
Oak Grove Butte is now a 3 mile RT hike with 750 feet of elevation gain. The rest of the write up here :http://www.pnwsota.org/blog/k7atn/2016-october-29/oak-grove-butte-or-october-2016, is generally correct, except the passive repeater now has a big brother and the road to that tower is good gravel. However, a gate blocks this road at the final intersection.
Driving Directions:
I attempted to activate South Mountain (and Summit "1540") in the South Olympic Region. The land is owned by Green Diamond Resource Company. It looks like they have taken a page from Weyerhauser's play book and require permits for entry into this restricted use area of Mason County. See: https://nwpermits.greendiamond.com/ At the time of this writing, annual permits started on Sept 1 and Motorized permits cost $425 Ouch!
Stimson Lumber is the property owner for David Hill. Their public access policy is fairly generous, and most of their parcels are open for walk-in use. However, a few of their areas as listed as Sensitive Areas and closed to access. Until recently, David Hill was one of these areas. With a recent change it's now accessible, and a short hike will get you to the summit.
I tried an alternate route to 5060 (aka Full Quieting Mt.) in the Gifford Pinchot.
I parked at (46.10557, -121.66125) on NF-2360-071 (aka Eckhart Pass Road).
Proceed South up the ridge, which is mostly open with some deadfall/blowdown for about 0.55 miles. There is a false summit, just continue south.
Double Peaks is a 4-point summit in the Mt. Hood National Forest, 2 miles west of Olallie Lake. The entire area is a burn scar, so expect loose dirt and rocks, burned treefall, and no shade. The area is 2 miles west of the Warm Spring Reservation and lies squarely in the National Forest.
Climb: 3.2 mi, +2,423 feet (From White River trail at Cliff Creek)
Approach: 27.4 mi., +4,544 feet, -4,281 feet (From Benchmark)
Cox Benchmark is a Drive up summit near Lakeview OR.
There is a small RF site on top, but we experienced no interference from it.
The last bit of road, approximately one mile and 500 feet of gain, is a bit rough and overgrown in places. We drove it in a Rav4, but you could park near the start of it at 42.39478, -120.36527. This would avoid needing higher clearance and northwest pin stripes.
Abert Rim is a 6-point drive-up summit in the Warner Mountains area of the Fremont-Winema National Forest.
Fish Creek Mountain is a 6.3 mile RT hike with 2300 feet of elevation gain.
Access to the trail head is on good roads, mostly paved with good gravel for the final bit.
