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.

East Canyon Ridge is a summit in the Gifford Pinchot National Forest, near Mt. Adams. The summit is along a well used multi-mode trail that sees some mountain bike and moto traffic, though very light on the day of my activation. Huckleberries were ample during my visit in late summer, as well.

Climb:                   4.6 mi, +3,170 feet

Approach:           11.8 mi., +1,102 feet, -925 feet

Getting there: I rode my mountain bike from Sherman Pass, activated Columbia Mountain, and then continued on to Wapaloosie Mountain before backtracking and descending Jungle Hill. Trails are in decent enough condition and there is nothing about the tread that would make them difficult to hike. I did drive the roads to all the trail heads and the road to this one is in good condition. I found it quite passable in my Subaru Forester.
