For the most part all of K7ATN's blog post here(http://www.pnwsota.org/blog/k7atn/2019-september-06/eagle-cap-or-septemb...) is current and probably some of the best info you're going to get. One thing to note earlier in the summer is the possibility of snow. Unfortunately I don't have a picture of the more direct approach, which I labelled 1 in the map, but much of the trail was under steep snow field.
Sleeping Bear Dunes Naional Lakeshore has a number of SOTA summits - Shauger Hill might be considered to be in the heart of the Lakeshore. Note That the official NPS map shows "Shauger Hill" (E on the map) quite a distance from the USGS coordinates used by SOTA.
Take M-109 off of M-22 and check in at the entrance station - this is a fee park. I recommend getting a copy of the Lakeshore map to follow the one-way Pierce Stocking Scenic Drive and the numbered features.
Summary - This traverse starts from the Silver Star trailhead (45.78080, -122.24362) and links Silver Star Mountain with 3977 (Discriminator). Covering roughly 8.5 miles and 2800 ft of elevation gain, it has amazing views, some steep sections, and a bit of scrambling. Do 3977 first to get the toughest part of the hike behind you, enjoy the big views on Silverstar and have a mostly downhill walk back to the trailhead. From SE Portland to the trailhead is about ninety minutes. Caution advised when planning the drive: FR41 is not Prius-friendly.
Summary - Hiking Three Corner Rock and Birkenfeld together combines good views, no views, an open summit, a forested summit, a long hike, a stiff bushwhack and decent elevation gain. You can do this TRC first or Birkenfeld first. Starting at the Rock Creek Pass trailhead (45.74910, -122.04310) follow the PCT east to (45.71410, -122.00700). From here you have a short steep bushwhack up the ridge to the summit of Birkenfeld. Come back down the same way and return to the way you came, turning off the PCT to the Three Corners Rock trail.
Peak 1980 is on Washington State DNR land approximately 1 hour, 15 minutes north of the Portland Metro area and about 6 miles south of Cougar, WA. This land requires a WA Discovery Pass.
The summit is a drive-up, but the last .75 miles is rough and a mid-clearance vehicle with AWD or better is recommended. See SOTL.AS or Sota Maps for the route GPX file.
There are a few trees remaining for a wire and open space for a vertical. I made one contact on 2m into the Portland Metro during a weekday morning using a half wave whip. You should do better on the weekend.
After sleuthing some maps in Gaia GPS, a means of access was determined for Green Mountain. It should be noted that most mapping sites do not have good or accurate maps for this area. Prior reports cast some doubt but the route provided is all on public land, Washington DNR to be specific. On my trip, the outer gate was locked but the land is not signed as prohibited for access, so i hoofed it in. If you park at the gate, don't block it and bring your Discover Pass.
This year I'm particularly interested in first activations. One of the few remaining unactivated peaks within a couple hours drive from Seattle was Ebey Hill near Arlington, due to the access issues described in this previous pnwSOTA post by WA7JNJ.
The hike to Bob’s has almost doubled. From just over 3 mi RT to just over 6 mi RT. Elevation gain increased 400ft from 1100 to 1500. The Washington DNR has placed a new gate at 45.64596, -122.20734. There was no signage and I am not sure if the gate will always be closed. But seems prudent to plan on the longer hike. There is plenty of parking near the gate. Hopefully this will cut down on the amount of trash on the hill, which was always the down side of doing this peak.
Just an update: the road to the trailhead has been re-gravelled since we activated in 2023. Discovery Pass still required.
And it is possible to get closer to the summit by parking next to the electrical tower at (45.658181, -122.183540).
Bring a climbing helmet for this summit! Even under the trees, you're in the kill zone for falling rocks!
