Cascadia is a term generally given to the Pacific Northwest that includes everywhere from the Cascade Mountains and west out into the ocean. From Northern California up through Oregon and Washington to Southern British Columbia the whole interconnected area forms Cascadia. I just spent the last week investigating earth system interactions in this region and how humans interact with these systems.
If you are wondering what I mean by earth system interactions, one examples would be how sediment gets moved from a hill-slope, down a river channel, then out to sea. But you will see what I mean from these pictures.
Here is Mt. St. Helens which last erupted in 1980. This is a classic example of human and earth systems interactions because geo-hazards like this directly impact peoples life choices today. Don't worry about the black-ish dot in the sky, that is an annoying piece of dust that got stick on my lens.
This really cool piece of gray earth (andesite for those interested) you see in the above picture in the middle right is awesome for two reasons. First, it is an intact piece of Mt. St. Helens that traveled extremely far in an avalanche during the lateral blast of the eruption. It didn't just travel, it traveled intact, as in all of the layers and position of every grain stayed in the same place relative to one another. That is extremely hard to do unless you travel down slope hundreds of miles an hour. If you go back to the picture above Mt. St. Helens you can see that is how far it traveled, because I am standing in the same footprints for both pictures (about 12 to 15 miles). The second cool thing is that the whole rock was shattered into gravel sized grains (which is why you see so much erosion in it now). From far away though it appears to be intact, but everything was just shattered in situ from the explosive eruption.
Also in the last week I went out on the R/V Elakha to take water column samples in the Yaquina Bay. I'm on the left here putting in some of our equipment. These samples will be used for data for an ongoing pulse-checking that we do on the Bay to determine how much humans are doing to change it.
song that I am listening to currently is
Tell Me A Tale by Michael Kiwanuka
Hi, I'm Nilo. Living in Oregon I mostly enjoy sports by the season. Summer is mountain biking, kayaking and climbing. Fall is kayaking and surfing. Winter is skiing and backcountry skiing. Spring is kayaking and late skiing. All with some traveling thrown in there
