There are several ways to get to Green Point Mountain - I choose the shortest hike, which of course required the most uncomfortable drive (i.e., high clearance and paint you don't care about).

Peak 4740, OR | August 2016
Just north of Detroit, Oregon are a nice bunch of summits - Peak 4740 is more of an...let's say...adventure. From where I parked it's less than a mile to the top - some on a rough road and some "cross-country" travel.
Tanner Butte, OR | August 2016
Tanner Butte is perhaps the most remote SOTA summit in Oregon's Northern Cascades. Despite many resources that point out the trail length at 17 miles, measured from the GPS track it shows up as right at 20 miles round trip, with 4500 feet of elevation gain. You won't see many other hikers on these remote trails.

Wildcat Mountain, OR | July 2016
It makes for a very long day (about 17 miles total), but this Wildcat Mountain (WV-046) can also be reached from Huckleberry Mountain via the Plaza Ridge Trail #783 and the Douglas Trail #781. It's also quite beautiful - a stunning ridge hike in the Salmon-Huckleberry Wilderness.
Stormy Mountain, WA | July 2016
A nice hike through second growth forest will get you to the former fire lookout site on top of Stormy Mountain. You might consider activating Slide Peak, W7W/CH-202 as you'll be passing right by the trailhead for that summit.
Slide Peak, WA | July 2016
A short, steep and rough climb will get you to the summit of Slide Peak.
Red Hills of Dundee, OR | Sept 2016
Red Hills of Dundee HP is a summit on private property with all of the Activation Zone apparently also on private property.
Githens Mountain, OR | July 2016
Githens Mountain in the Clackamas River drainage is a short, one mile hike and only about 500 feet of gain. It can be activated along with nearby Tumala (Squaw) Mountain from the same trailhead. Finding the summit may require a GPS, as it's not on the trail and isn't particularly distinct.
