Route: Howlock Mountain Trail #1604

The Howlock Mountain Trailhead is near the Diamond Lake Resort off OR 138.

Route description from Summitpost:

"From the trailhead, take the Howlock Mountain trail east through a tunnel under Highway 138 and continue 1.1 miles to a junction with the Spruce Ridge Trail. Stay left here on Howlock Mountain Trail for another 2.4 miles just past Timothy Meadows to a junction with the Thielsen Creek Trail. Do NOT take this trail! Stay on HMT left another 3.5 miles to where the trail ends at a junction with the Pacific Crest Trail. Turn right and go maybe 100 yards to an open clearing where you can see the saddle ahead to aim for . Head due east (left off the PCT as you travel south) for the saddle cross country. Gain the saddle and walk the ridge left (north)."

"The ridge forms a "Y" here. Left ridge heads up to the pinnacle formation which you can scramble up the southwest side in a shallow gully (be careful-very loose and crappy plates) or you can also go to the northwest side of the pinnacle via the south and then west sides. SP'er cjwhat says the northwest side is better that the south/southwest side although still loose. Right ridge goes to the higher east summit and it achieved by scrambling up the ridge. Also LOOSE rock at the summit. Be careful!"

"Descend the same route. Total length of this route is about 15.5 miles round trip with 2700 feet of elevation gain."

I followed this route to the east summit, then climbed the west summit (pinnacle) by traversing on the west side and scrambling up the northwest ridge as suggested by Summitposter cjwhat (class 3-4, some decent rock).

In spite of the elevations recorded on the USGS 7.5 minute Howlock Mountain map, I believe the west summit (pinnacle) is higher than the east summit, as suggested in the photo below.
