Next up we're visiting Waespe Falls, one of the tall seasonal waterfalls between Multnomah Falls and Oneonta Creek. This is a short distance east from Nesika Falls, its equally obscure neighbor just down the road. Of the two, this one has probably been glimpsed by more people; if you start at the Oneonta trailhead and follow the trail uphill a short distance to the junction with Gorge Trail #400. Just west of there the 400 crosses a small stream. If the creek is flowing, look uphill from there. It's a steep talus slope mixed with trees and vegetation, and includes a bit of old stone wall that -- I think -- was built as a rockslide barrier and isn't part of an abandoned road or trail. Beyond that and higher up, the steep slope becomes a high basalt cliff, and the falls are where the nearby creek tumbles off that cliff. Alternately if the creek is flowing and the forest isn't too overgrown it may be visible on Street View, like here for example.
Like Nesika, the name is of fairly recent origin and either originated or was popularized on the OregonHikers forums. In particular, the oldest references to it by name -- any name -- that I've seen anywhere on the interwebs are a pair of 2011 OregonHikers threads. Which were followed by later ones in 2013 and 2022, and most of these involved someone bushwhacking up to the falls by following the creek straight uphill. Some people reported that the climb was "easy", while others found it impossible, mostly due to all the loose rocks they had to struggle through. One of the posters who made it to the base posted some photos to SmugMug like this one. And those links along with the Northwest Waterfall Survey page linked up above are about the only information there is about it online.
The name is also not official, or really recognized much beyond the Northwest hiking and waterfall hunting corners of the internet. It's derived from Waespe Point, a prominent rock formation next door to the falls. And the point was named in 1983 to honor the late Henry Waespe, a prominent local citizen and president of the Trails Club in the 1950s. I have no idea how to pronounce that name properly, but I think the name of the falls should be pronounced "wispy" even if he didn't say it that way himself, because it just sort of fits that way.

As with Nesika Falls, Waespe Falls is rather tall (when it hasn't run dry for the year), and there are no published numbers on exactly how tall. So let's go back to Oregon's official state LIDAR map and see if we can figure that out. On the state LIDAR map, with both the "Bare Earth Lidar Hillshade" and "Bare Earth Slope (degrees)" enabled, pick two points on the creek that are as close to what appears to be the top and bottom of the falls, without actually being part of any vertical drop. The lowest-slope points you can find on either end, so ideally the top is just before the stream abruptly falls off a cliff, and the bottom point is anywhere on the perfectly flat and calm pool the falls drop into. If you don't try to do this, your results may vary widely depending on exactly which pixel you clicked on this time and exactly how the map converts that into six decimal places of latitude and longitude. I like to try this a couple of times to see whether the numbers are anything close to reproducible. In any case it might be useful to think of this as giving an upper bound, like you probably won't come in short of the actual height unless you're doing it all wrong. So, bearing that in mind, and note that I'm counting what looks like three adjacent tiers together as one big waterfall (and using these top and bottom points), it seems to be around 425' high, roughly the same height as Nesika.
Since I was in the area, so to speak, I did the same thing with a couple of other intermittent streams in the short distance between Waespe Falls and Oneonta Gorge. The first one east of Waespe comes to "just" 240' and may disappear into a talus slope after that. (top, bottom), while the next-east one from there seems to come to around 650' in 4 distinct tiers (top, bottom), and a third immediately east of that (top, bottom) comes in at around 385' in 3 tiers, and it also seems to sink into the ground below the drop. So none of these are going to be very substantial and I don't recall ever seeing any of them flowing in person, either close up or from a distance. I suspect they go beyond "seasonal" into "ephemeral" territory and only flow during and maybe right after a big rainstorm and are otherwise dry year-round. I tend to draw a line there as for what's included in this ongoing project, for the very practical reason that if something only flows during a big storm, it means you have to do a lot of hiking during big storms. And in this part of the world, doing that means spending a lot of additional time being cold and miserable, which I am generally opposed to.
Meanwhile to the west of Waespe, between it and Nesika Falls, is the big talus slope that's home to the "Fire Escape Trail", which we already covered in the Nesika post.
Also (going by the very terse directions) the falls might become an ice climbing spot known (as of 2019) as Unfinished Business; Northwest Oregon Rock (published that year) noted it was about 200' high and up to that point nobody had climbed it past the first 80 feet or so. We haven't had a lot of extended cold snaps since 2019 around here, so that matter may still be unfinished, as far as I know. I can tell you it won't be me who climbs it; I only bought the book because it's kind of a whole alternate geography overlaid on a part of the world I know reasonably well, and because it turns out that some of the best ice climbing spots in the Gorge double as very photogenic (yet very obscure) seasonal waterfalls when they aren't frozen.
I checked the Oregonian database to see if anyone mentioned seeing a waterfall near the Oneonta trailhead before the internet. I don't think I found anything like that, but somehow came away with a bunch of links anyway. As usual, this is the part of the post where it helps to have a Multnomah County library card so that the links below actually take you somewhere useful.
(If I wanted to go off on a very long tangent here, and thought anyone might be interested enough to read it, or I was interested enough to write it anyway, Waespe's family was socially prominent enough that you could assemble a whole biography of him just from newspaper articles. From birth announcement to obit, with society weddings and business and philanthropic stuff in between, and leading a lot of Trails Club hikes over the years. But that would be quite a long tangent and if you're really that curious you're welcome to get out your Multnomah County library card and go write that book (or at least a Wikipedia bio, or something).)
- An October 1934 story on the shiny new Horsetail-Oneonta Loop, just completed by WPA workers. The author describes both creeks in great detail, including a number of side trails that are either lost or abandoned now, like one to what it called "Pathfinder falls", a pair of waterfalls between Triple Falls and the first trail bridge on Oneonta Creek (there's a second bridge above Triple Falls, and maybe more further up.) One of those would have to be Upper Oneonta Falls (or Middle depending on whose naming scheme you use), but I have no idea what the other one would be. The article doesn't mention anything Waespe-like, but at the end he does say there are a lot more sights and side trails beyond those he just told us about.
- A 1939 story about good picnic spots in the Gorge. Says people overlook the trailhead and just think of the Oneonta Gorge itself, which is basically still true, even though it's been closed since 2017 due to the fire. The trailhead itself isn't very photogenic on its own.
- A 1953 story concerning a timber swap between the Forest Service and a timber company that preserved some land along Oneonta Creek, trading for land of equal value somewhere outside the Gorge. A little mixing business with philanthropy: You get positive headlines, and the equal value swap gets you more land and trees. The article suggests the swap would make possible an alarming idea that was making the rounds at the time:
Its becoming a part of the public preserve will make more feasible a road up the Oneonta trail, which would cross the Oneonta near a triple falls and approach the upper Horsetail falls before descending again at Ainsworth state park on the old Columbia highway.
- A 1970Leverett Richards article on the Horsetail-Oneonta loop, which he refers to as a "granny trail". Mentions that the trail forks near the end and you should take the right fork to get down to the highway. Doesn't say where the other fork goes, assume it's some predecessor of Trail 400 but it seems a bit early for that.
- In a sign that the 1970s really were an extremely long time ago, a 1971 story about Multnomah County sheriffs deputies setting up a sting to catch car prowlers. Now they just sort of accept that nothing can be done about it, any more than you can affect the weather, and it's probably your fault anyway for having objects (valuable or otherwise) in your car, and really for going outside in the first place when you should be in church or cowering at home watching Fox News.
- November 1979 Roberta Lowe article in the Oregon Journal, laying out a hike starting at the deeply obscure Exit 35 trailhead and ending at the Oneonta trailhead, these points chosen because Trail 400 on either side of those was still unfinished. For people looking for an advanced challenge, this article -- in a major urban daily newspaper -- explains how to find the 'infamous' Mystery Trail, which (almost) nobody on the internet will even give you directions to now because someone might try it and get hurt. You can be sure it's dangerous when even she says not to go beyond the first 3/10 mile on it, though she also insists that initial segment is a "fun side trip". I should note that present-day conventional wisdom holds that this is a down-only trail and taking it uphill would be an ridiculous idea. On the other hand, the newspaper archives show Mazamas hikes doing exactly that on a semi-regular basis back in the 1930s and 1940s, and the instructions don't say anything about bringing a can of spinach to chug for energy, so who knows.
- March 1980, Lowe on the nearly complete Ak-Wanee Trail, an old name for the Multnomah-Oneonta segment of Trail 400. Mentions the Elevator Shaft branch and the abandoned spur trail to Nesika Falls, but nothing about another seasonal falls near the Oneonta trailhead. Does mention the unnamed 'turnout' for the 400 down from Nesika Falls at least
- July 1982, some killjoy editor must have pestered Roberta Lowe to cover some hikes for mere mortals for a change. Her idea of this was setting up a car shuttle and doing the Oneonta Trail as a "lazy, downhill trip" from the top of Larch Mountain. Which, yes, is downhill. For 8 miles. And to spice up the trip without making the hike itself harder, she notes that you can shave 8.5 miles off the car shuttling part of the trip by taking Palmer Mill Road (a steep, narrow gravel road, at times with a sheer dropoff into Bridal Veil Creek) instead of driving all the way west to the ordinary Larch Mtn. Rd. junction west of the Vista House. You can still do the lower part of that to where Palmer is closed to vehicle traffic and then follow Brower Rd. up instead, which saves miles but not as many. Energy crisis was barely in the rear view mirror then, and we have high gas prices and inflation again now, so I'm not telling you not to do this; just saying it's not exactly a luxurious driving experience, and your vehicle is probably larger (and wider) than the average car of 1982.
- It was back to business as usual in August, with a 9.6 mile loop along the Franklin Ridge Trail, and a 10 mile loop that includes a trip up the unofficial and rather steep Rock of Ages Trail. Because when your newspaper is going out of business in another week or two, you might as well swing for the fences.
- Within a couple of years the Oregonian decided the Lowes were ok; here's a 1987 piece on the long-abandonded but newly reopened Bell Creek trail. Bell Creek is an Oneonta Creek tributary that begins on the upper reaches of Larch Mountain, and is remote enough -- and/or lucky enough -- to be home to a grove of genuine old growth trees.
