First the TL;DR: This is a five star bike ride. I HIGHLY recommend this route. This route passes many different trailheads and parking areas along the Deschutes River, so it is possible to put together a ride that is shorter and easier. Much of the route is gradual uphill with Lava Butte itself being the real kicker.
Good Parking At Trailhead
2670 Git Out Ridge
Git Out Ridge is a a 2 point summit located about 5 miles north of Gold Bar. The 6.8 mile (roundtrip) hike begins at Spada Lake and is mostly a walk on a gravel road. About 1/3 of the hike is on an abandoned section of road that goes through the forest. Total elevation gain is ~1300'.
Driving Directions:
Take Highway 2 to Sultan. Take the Sultan Basin Road north. Most of the way is paved, but the last 1/3 of the road is gravel. We went in a Prius and had no trouble - the gravel road is in good shape. Keep following the road until you arrive at Spada Lake Dam.
Old Blue Mountain Oregon
Looking over the map and seeing a named peak with no activations is just more than I can handle, especially when K7ATN's blog post left the slightest hope that there may be a way to get there. After hours of poring over maps, I came up with a plan.
3537, WA | April, 2021
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.
Grayback Mountain | April 2021
It appeared to me that access to Grayback Mountain was possible to summit from the South staying off of Yakima Nation Lands. I also found a trail map with access and photos of the summit from 2019 here: http://www.willhiteweb.com/washington_fire_lookouts/grayback_mountain_lookout/map_300.htm
Activating Mt Hood via South Side Route | March 31st, 2021
NOTE: Conditions on Mt. Hood can change weekly, even daily. Consult up-to-date weather, avalanche, and beta reports.
On March 31st, 2021 I took advantage of a weather window and reasonable avalanche forecast to activate Mt. Hood (W7O/CN-001) via the standard South Side route.

I activated this on the 14th day of a 15-day backpacking from the Elk Mountain Trailhead, via Mink Ridge & Marten Creek with a side-trip up Marten Creek to Marten Hot springs; but the route description is the more direct route across Goat Creek and along the Square Rock & Moose Ridge.
