Early Winter in the North Cascades and Eastern Washington

On Thanksgiving Day, November 28, we traveled to eastern Washington, though not the nicest way to spend the day.  The day was a disappointment especially because we intended to go out for dinner together but found nothing open and ended up eating food from a gas station for our dinner, myself a dried out burrito and my wife a couple of fried chicken legs.  We thought we would make up for the disappointment of not being with friends or family on the day by taking the North Cascades Highway, a very scenic route, through the mountains, but by the time we got to the mountains the sun was already setting and though we were able to get some good pictures, traveled most of the way in the dark.  These are the pictures we took, mostly taken by my wife who had forgotten her camera and was using mine.

The next day when in Medical Lake, Washington, our destination, my wife went for a walk and took these pictures, again with my camera.  The day was cold and there was a lot of hoarfrost on everything which made for some spectacular pictures, but the weather with predication of freezing rain forced us to leave early, though the predictions proved wrong.  In any case, these are some of the pictures  she took, rather spectacular pictures, in my opinion and well up to her usual standard.  I especially like the monochrome tones of many of the pictures, ins some cases with a hint of color as well that in the pictures looks like they were selectively edited for color.

Fossils and Fungi at Slide Mountain

I made two visits to Slide Mountain recently, one with son Edward and one with a group of school children who were studying fossils in their science classes and wanted to see some of the fossils at this amazing site. Slide Mountain is in the foothills of the North Cascades and overlooks the North Fork of the Nooksack River and the valley below with the mountains of the Canadian Coastal Range visible in the distance.

The day Edward and I went we met up with some of his co-workers and spent most of the day on the mountain.  The weather started out sunny but turned cloudy making pictures of the slide area difficult, but on the second trip I managed to get some better photos.  It was drier, too, the second time.  The first time Edward and I had come home filthy after a very muddy scramble on the mountain and in the area of the slide.

Slide Mountain is named for its tendency to produce major landslides and the areas where we hunted for fossils were the sites of very old landslides, mostly overgrown with brush.  The most recent landslide happened a few years ago on the side of mountain facing the Nooksack and its tributary, Racehorse Creek, and that is where we spent most of our time exploring and hunting for fossils uncovered by the slide.

The Racehorse Creek landslide happened on January 5, 2009, after a days of warm stormy weather and rain (what we call here a Pineapple Express).  About 500,000 cubit feet of rock and earth slid down the mountain and into Racehorse Creek temporarily blocking the Creek and two days later causing a massive flood of water, rock and timber down Racehorse Creek and into the North Fork of the Nooksack.

On both of these excursions we visited Racehorse Falls and the creek below and the photos show the debris from the landslide which scoured out the area of the falls as well.  Before the landslide and flash flood the area was grown over with trees and brush and the falls were not that visible.  Now the way to the falls is a scramble over old tree trunks and boulders but the falls are visible from quite a distance away.

The landslide left a 350 foot cliff in the side of the mountain and uncovered thousands of Eocene fossils, mostly of plants, though bird tracks have also been found.  The debris field itself is a jumble of boulders and timber and the best place to look for fossils, though it requires some serious scrambling, but the fossils can be found all over the mountain and we looked in several other places as well.

The mountain is formed of layers of soft carbonaceous shale, which quickly weathers and crumbles, and layers oif Chuckanut sandstone visible in the photo of the cliff.  The fossils are found in both with inclusions of coal as well.  This is a photo of a whole palm frond and pieces of other fronds in shale.  The rock is around four feet long and several feet wide, to give an indication of scale, and many other of these fossils are massive.

Palm Fossils

Along with the numerous fossils of palm fronds, we found huge imprints of their trunks and smaller fossils of ferns and conifers and even a section of bark that had been turned to coal.  The mountain must be made of fossils or so it seems when one is there.  Every stone, every boulder, seems to have something on it or in it and it is for that reason a favorite place for field trips from the local University, Western Washington.

Along with the fossils we found all kinds of interesting fungi, lichens and mushrooms and polypores and spent as much or more time photographing them as we did the fossils.  I've done my best to identify them, but my identifications are in many cases tentative and I am happy to be corrected.  Autumn is a good time for fungi anyway and the numerous dead trees destroyed by the landslide meant there were even more of them than usual.

A few other finds included autumn leaves, frosted leaves and fern fronds, and a Woolly Bear Caterpillar, which I learned develops in autumn, freezes over the winter, unthaws in the spring and then turns into the pupa of a moth.  It produces a kind of antifreeze that keeps it from death when it is frozen.  There is always something to learn and always something amazing and new and this place was a learning experience.
