Larch Mountain Crater Loop

Here are some photos from a loop hike around the crater atop Larch Mountain. And, well... it's less scenic than you might think. I guess because it mostly wanders around down in the densely forested bowl of the crater, which tends to rule out distant horizons. You also don't get any of the dramatic things that come to mind when you think of volcanic craters, like bubbling pools of lava, or magic rings being forged or tossed into said pool of lava, or Robo-Ahnold melting in lava, though come to think of it that was molten steel and not lava, but either way, no melting Robo-Arnolds. Also no stinky fumaroles, or geysers, or boiling mud pots or anything like Yellowstone, or anything like Crater Lake either. No B-movie starlets being tossed into the crater to appease a primitive volcano tiki god. No dramatic springs bursting forth at the headwaters of Multnomah Creek or Oneonta Creek, just sort of a swampy muddy area with some water trickling out here and there. There aren't even any dramatic vistas looking up at the crater rim or the Sherrard Viewpoint from below. Although you may get a bit of that if you go off-trail and try to find the talus slopes downhill from the viewpoint, but when I took these I was pretty content with just a quiet low-key stroll through the forest along the official marked trails.

Going off-trail also runs the risk of blundering into the forbidden Bull Run Watershed immediately next door. In fact a short stretch of the Oneonta Trail actually passes inside the watershed boundary. The trail also intersects a couple of old logging railroad grades that look a lot like hikeable trails but will take you deep into the Forbidden Zone (note this dates back to a time when the city was ok with clearcuts in the drinking water reserve, a practice that was finally abolished in the early 1990s(!), and check out my Forest Road NF-1509 post for more on that if you're curious). I seem to recall there are signs at these spots telling you not to go any further, and if you're the sort of person who doesn't read signs or doesn't think the rules apply to you, you probably don't spend your time reading obscure humble blogs either, and I'm wasting my time trying to explain this... Yeah. Anyway, this is one of a short list of sorta-unusual hazards you might encounter on the otherwise fairly chill route around the crater.

Another, I guess, hazard to be aware of is that several of the trails around here are marked for use by mountain bikes as well as hikers, which is fairly unusual in the Gorge. I did encounter a couple of them on the way, zooming downhill rather quickly. It was fine, though; they passed without incident, and no "Coexist" bumper stickers were angrily scraped off that day, and I am not actually complaining here, just pointing out the one unusual thing to keep an eye out for. The Cycle Map layer on OpenStreetMap shows which trails allow bikes, and I think the main limiting factor on which trails do is the Mark Hatfield Wilderness boundary. You see, the federal Wilderness Act of 1964 was written long before the mountain bike was invented, and the word "bicycle" does not appear anywhere in the law. But the law prohibits any "other form of mechanical transport" within wilderness areas (right after explicitly banning cars, motorboats, and aircraft), and that phrase has generally been interpreted to include bikes. But not canoes or rowboats, because reasons. By contrast, the law also says nothing about bringing personal electronics along, and technically does not prohibit you from bringing a laptop, connecting to satellite internet, and whiling away the hours with some backcountry crypto trading, or being extremely mad online about the latest superhero movie, or grinding out some Python code for your latest startup. That would merely violate the spirit of the law, but seemingly not the letter of it.

The other unusual thing to keep an eye out for is dumb SUV drivers who can't tell a hiking trail from a forest service road. There was an incident around September or October 2024 where someone decided they would rather not to do the quarter-mile hike from the parking lot to the Sherrard Point viewpoint, and decided to drive down the trail instead. Admittedly the first part of the trail is paved and almost looks like it could be a one-lane service road, if you decide the signs saying it isn't a road don't apply to you. They got a few hundred feet down the trail before sliding off the non-road, and only a couple of trees kept it from tumbling all the way down into the crater immediately. The driver and any passengers must have just abandoned it where it was, and then the Forest Service did not come up with a way to safely remove it in time before it broke loose and tumbled the rest of the way down into the crater. Or at least that's what I heard eventually happened; I only saw it when it was still perched there just off the trail, and I was there after midnight to see the aurora and stumbled across it by flashlight, and at first didn't realize it had already been there a couple of weeks. So obviously I had to look it over a bit and make sure there wasn't anyone inside that needed help. Now that's a creepy thing to run across at night in the forest. I'm not saying you're very likely to encounter a ginormous SUV four-wheelin' it down the trail here, or a recently wrecked one that failed at driving down the trail, but it's already happened at least once, so the odds of it happening again are clearly greater than zero.
