Drool-Worthy Geology at Whatcom Falls Park

Sometimes, having your plans fall through is the best possible thing. B and I headed up to Mount Baker yesterday to get you all some lovely volcano photos. Alas, the haze in the air was so thick you couldn’t see across a lake, so voluptuous volcanic vistas were not in the cards. The weather was cool enough for some Puget Lowland adventure, though, so we picked a park and went hiking.

We were lucky enough to discover Whatcom Falls Park, which is along short little Whatcom Creek. It’s not at peak flow right now, so the waterfalls aren’t as majestic as they are in other seasons. However, this is a prime time to see the geology of the stream bed. It is bloody spectacular.

Look at all that beautiful sandstone! That’s the Chuckanut Formation. This is delicious sand eroded off a majestic mountain massif and deposited peacefully in a serene coastal plain just over 50 million years ago. You can find neato fossils in it in places, though we didn’t see any, sadface. Still. It’s completely coolio without. I know you lot wanted volcanoes, but c’mon, sandstone waterfalls are still pretty great, right?

We walked all over the top, and inspected the gorgeous patterns left by erosion, such as the following:

There’s a reason why there’s still a half-decent water flow on this half of the falls: it looks like a pipe is bringing runoff from other areas, and creating its own lovely waterfall just up the bank.

So the waterfalls there are excellent, and there are several outstanding swimming holes that people seemed to be thoroughly enjoying. But the park has more to offer! Like this astoundingly interesting tree growing along a trail.

Image shows me standing beside a forked tree that had started growing sideways and is now growing up. It looks like a sculpture more than a tree.
Believe it or not, this tree is still alive.

I have nine trillion pictures of it, because it was that cool. I’ll share some more later. You’ll love them, I promise.

There’s a side trail to some overlook thingy, and as you’re walking, you’ll notice more and more abundant lumber in the trail. Then you get to the end, and you discover why: this is an old railroad bed, and the trestle is still there.

There’s lots more to see – ponds, and wetlands, and you can make it all the way up to Lake Whatcom, where the creek originates. I’ll show you those soon, but let us fast-forward to the end of the day, when we went down to Marine Park to view the beautiful bay. Alas, the haze obscured the views by quite a lot, but we found lots of fascinating stuff on the beach. Like these barnacles growing on seaweed, of all things.

Barnacles on seaweed? WTF?!

Here’s one more image, showing just how many barnacles were growing all over this thing: note they’re attached all the way down the strip.

Look to the bottom right: so many barnacles! Charles Darwin would be screaming with joy.

We found a lot of really super oyster shells, too, which will make S happy, as he likes to sculpt things from natural objects. Love it.

So it was a lovely day, despite the lack of volcanoes. We’ll see what I can get for you explodey-wise tomorrow, but before you feel completely bereft of explosions, just keep in mind that Whatcom Creek kinda blew up due to a gasoline leak in 1999, so there’s that. It was rather tragic, with three people killed, and damage to the stream that’s still being repaired today.

Damn. That’s a bit depressing. Let’s hope we get some hawt volcanic action for you so that happiness can reign again.

    Looks like a very lovely hike! The combination of runoff pipe and swimming holes worries me a bit, though. (Okay, in real life if probably wouldn’t worry me enough to avoid swimming there.) I love how the barnacles-on-algae look like a tentacle. Also, I’m curious to see S’s oyster shell sculptures.

    That haze you had at Baker was probably due to smoke from the massive wildfires going in BC. Due to unseasonably dry and warm weather, which is totally NOT caused by climate change, no indeed, nosiree, not at all.

    I was going to mention the gasoline leak fire, but you got it covered!

    Barnacles on seaweed? WTF?!

    Barnacles will attach themselves to anything reasonably firm. Kelp fronds are prime barnacle nesting places because barnacles are filter feeders, depending on currents to bring them food and since kelp are also moving, the barnacles are exposed to more potential food than barnacles stuck on rocks.

    Those barnacles are so cute!! Loving the tentacle-like aspect, too. :D
    What is it about waterfalls in forests? It’s almost like they’re magic or something… Plus the added touch of slowly decaying human elements. Very mysterious, very haunting, and absolutely beautiful.
