Ascent Trip ReportMt Hebo has two summits that compete for its prominence. The SW summit, with a 3160' contour but no spot elevation, is in Yamhill county. The NE summit, which has two 3160' contours, one of which has a 3176' bench mark, is in Tillamook county. If the Tillamook summit takes the prominence, the Yamhill summit gets a paltry ~260 feet of prominence and the county prom champ is Trask Mtn, the HP. If the Yamhill summit wins, its prominence range overlaps that of Trask, and it becomes a contender for the county prom point.
From US-101 in the town on Hebo, I turned E on OR-22. Just ¼ mile later, I turned N on the well-signed Mt Hebo Rd, which is identified as FS 14 after you are on it. Call this point mile 0.0. At 4.5 miles, pass the turnoff to Hebo Lake CG on the R. At 5.6 miles, pass an equestrian parking area on the R. At 6.9 miles, snow coverage precluded further driving, and I parked and began hiking, carrying my snowshoes. I estimate the elevation at this point to be about 2600'.
After only 5 minutes on foot, I reached the saddle at (45.2181N, 123.7627W, ~2800') where a trail that comes up from the Hebo Lake CG crosses the road, arriving at the exact same time as a fellow who was hiking the trail. We started a conversation, and I joined him on the trail, which we soon lost due to snow coverage. We headed cross-country to the towered SW summit of Hebo. During this time I learned he was from NY and was interested in the 46 Adirondack 4000-footers. I told him about peakbagger.com.
The 3160' area with a few towers is quite flat and its highest ground probably does not exceed 3165'. I hiked the short distance back S to the main Mt Hebo Rd and continued on it to the NE summit (in Tillamook county), donning my snowshoes due to deep snow. The 2-mile hike was easy and pleasant. Upon arriving at the NE summit, I visited the S countour first, where I found some rocks sticking out of the snow but no BM. Then I visited the N contour, which is definitely about 10' higher than the S contour. It is probably about 3185' or even 3190' by comparison with point 3176.
Owing to the fact that the Yamhill summit is probably less than 3165', and the Tillamook summit is at least 3185', I can rule out the possibility that the Yamhill summit gets the prominence of Mt Hebo. This leaves Trask Mtn, the county HP, as the sole possible contender for the Yamhill county prom champ. I'm willing to credit anyone who climbs only Trask for having reached the most prominent point in Yamhill county. Still, Mt Hebo is a worthy recreational destination, with campgrounds in the area, several trails for those who want to hike it in the summer, and snow-covered roads for hiking or skiing in the winter.
