Calamity Peak is a road walk or drive with a short bushwhack portion. Take Wind River Road north through Carson, WA. Turn west onto Hemlock and then north on Szydlo, which turns into NF-54. Follow NF-54 to the junction by the Soda Lakes trailhead, then go straight (rather than bearing left) to continue on 5407 to the junction with NF 324. Google Maps also gives good directions to this junction, 45.9118, -122.0982.
Bunchgrass Mountain is a bushwhack through meadows of bear grass (presumably its namesake), and trees and brush up higher. It eventually reaches an unavoidable steep push to the AZ, which rewards you with impressive nearly panoramic views of Wolf Rock, Latiwi Mountain, and others to the east. This is across the road from Wildcat W7O/CM-082, and across the highway from Iron Mountain, so they make a good pair or trio if you have the time.
One of the four Wildcat Mountains in Oregon, this one is a short bushwhack from a Honda-Fit-accessible road, and as it is directly across NF2655 from Bunchgrass Mountain W7O/CM-087, these peaks would make an excellent pair or trio with Iron Mountain.
On US 20, turn south onto NF15 and follow twists and turns, and several forks, to a sign on the left that says Fritz Wildcat, at 44.3437, -122.1303. Follow this road up to climb the ridge, and park at 44.3296, -122.1014, the saddle. Google has all these roads marked and it can get you there.
This is a decent stop-off on the way to the Marys Peak day use area. The easiest approach is from the west, which has the least gain and the shortest path up to the logging roads up there.
3537 is a 4-pointer right off Marble Mountain Sno-Park, and despite the busy climbing season it is easily possible to get in here and activate it. You might combine this with a summit of nearby LC-075, if you are feeling especially ambitious.
To get here, take I-5 to Woodland, then SR 503 which becomes SR-503 Spur, which turns into NF-90; turn left onto NF-83 and drive 6 miles to Marble Mountain Sno-Park.
East Crater is a peak in the Indian Heaven wilderness. Three years ago, the south side and ridgeline of East Crater were completely burned by a fire that ended up burning about 500 acres in the area, and this fire caused the evacuation of the entire Indian Heaven wilderness area in September of 2017. Not much has grown back on the south side, while the north side, essentially untouched by the fire, is thick with trees.
I approached this peak on a backpacking trip from the west, from Bear Lake, and hiked on Indian Heaven Trail to Lemei Trail; this made it 6 miles and 1100' gain. You can approach instead from Lemei Trailhead, making this a 9 mile, 2500' gain hike.
Gifford Peak is a forested summit above Blue Lake in the Indian Heaven Wilderness. This area is a popular destination for day hikers and backpackers, directly on the Pacific Crest Trail, so be prepared to meet crowds any day with good weather. The lake can be approached from either Falls Creek Horse Camp or the Thomas Lake Trailhead. Once there, take Thomas Lake Trail to the northwest corner of the lake, and proceed up the ridge off-trail. The ridge is pronounced and easy to follow to the true summit.
Henline is a relatively low traffic hiking trail in the Opal Creek Wilderness. It boasts rhododendrons, a mostly-well-maintained trail, and reasonably consistent gains. The hike is entirely on public right of way, and can be accessed via North Fork Santiam Road and NFDR 2207 from Hwy 22 out of Salem. Turn left on North Fork Santiam Road about 22 miles from I-5, then drive straight. Eventually this road turns to a moderate gravel road, followed by a fork between 2207 and 2209. Take the left fork and head uphill a ways. You'll pass the more popular Henline Falls Trailhead.
Bare Mountain is an easy bushwhack up from a decent-quality dirt road. There are several approaches, but this one is by far the easiest - and may have once been a trail to the summit. I recommend GPS, as there is no defined trail and coming down it is hard to follow your own tracks - though if you stay east of the original tracks you will still come out on the road. I could probably make it down NF-311 in a sedan. We walked from the pull-off on NF-311.
