Mount Bailey near Diamond Lake is a great hike to fantastic views but it requires some effort to get those views - about 10 miles round trip 

Cruising through Chemult Oregon at 6:40am, the dashboard said the outside temperature
was 29 degrees. This was far cooler than we anticipated for our attempt on Mt. Thielsen.
A few years ago, my son Andrew and I tried this summit but were driven off by mosquitoes
and our lack of DEET. I actually inhaled two of the beasts and slapped my glasses off my
face several times before we literally ran back to the safety of our car. The Diamond Lake
area is legendary for mosquitoes.

This morning was different. It was a brisk 36 degrees at the Mt. Thielsen trailhead. Seeing

Here's another summit in the Diamond Lake area to activate if you have a few hours. It's a drive-up, if your vehicle has moderate ground clearance and otherwise a short road hike. 

Buck Mountain is a summit with a short hike of less than half a mile that you'll want to do along with Coffin Mountain (W7O/WV-005) and Bachelor Mountain (W7O/WV-003).

Take Highway 22 east 19 miles past Detroit, Oregon and turn right onto paved FS 11.

On July 26, Olallie Mountain, W7O/CM-061, was activated for the first time.  Olallie Mountain has an elevation of 5,700 feet and is located in the Three Sisters Wilderness Area of the Willamette National Forest.  The trailhead is reachable by driving 50 miles east from Eugene, Oregon, on State Highway 126 to Aufderheide Road 19.  Between mileposts 45 and 46 on Highway 126, turn right onto Aufderheide Road 19 to the Cougar Reservoir Dam.  At the dam, turn left crossing over it.

Just north of Detroit, Oregon are a nice bunch of summits - Dome Rock is especially good. The Tumble Ridge Trail takes you to Dome Rock on a pleasant forest hike of only about 1.5 miles and 500 feet total gain.

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).

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.

Access:  Since SR26 is closed from the north due to a washout, you must come in on SR26 from the south. Take SR25 south out of Randle then SR99 west towards Windy Ridge.  At approx 7 mi in, take SR25 north to 1/4 mi past the Ryan Lake Interpretive Site road.  Take the TH road west for about 1/2 mi.

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.
