11:14 PM | Link Between Yellowstone And The Magma Plume Found, Imaged
It is like finding a leak in your roof. I remember once up at the cabin, noticing that my waders were full of water and pointing this out to my wife. “You’re supposed to hang the waders upside down. Keeps dead mice from falling in there.” Well, I thought, if any mice fell in these…

8:41 PM | Geo 1095: April 23, Day 843: Ollalie Creek
This is an isolated photo in this day's folder, and at first I wasn't certain what it's a photo of. But in terms of sequence, and comparing it to Dana's photos at the same location, it has to be Ollalie Creek. The Ollalie Campground is just off Route 126, where we pulled off to have a look at this entirely spring-sourced tributary to the McKenzie. The thing that threw me off is that I had forgotten what a large and voluminous stream it was. I remembered it looked awfully energetic, and that I […]

5:02 PM | King County LiDAR/Aerial Swipe Images
EM alerted me to this great swipe image images between LiDAR and aerial views the King County has put up: http://www5.kingcounty.gov/lidar/.Fun to play around with. The LiDAR imagery at closer range breaks down a bit compared to cleaner imagery one can also get from King County but still a great demonstration that captures why Dave Montgomery says it is like getting a new pair of glasses.

2:30 PM | Calbuco's Massive Volcanic Plume As Seen From Space
Two days ago, Chile’s Calbuco volcano erupted for the first time in over four decades . It spewed an ash cloud nearly 10ten miles high, resulting in evacuations within a 12-mile radius around the volcano. Here’s what the action looked like from space. Read more...

Earthquakes | Part 1 Today we’re looking at Earthquakes in a New Mini Series about these cool phenomenon. This whole shebang was inspired by the Chicago-land earthquake and honestly some misinformation about them in general. But this is an introduction to terms and to kick off the next following videos in the same thread. Stick around to see what else is happening! The USGS has some great resources about earthquakes which is where most of my ‘fact checking’ occurred. It also […]

2:14 AM | Calbuco Volcano Erupting
Calbuco is a volcano in southern Chile. This one erupts fairly frequently averaging about every 20 years, sometimes quite impresively. The largest eruption during historic times in Chile occurred at Calbuco in 1894. It is erupting now. Evacuations have been ordered. Here is some amazing footage:

9:50 PM | Geo 1095: April 22, Day 842: Full-On Koosah
I think this is the best view I've seen of Koosah Falls. There's a direct trail from the parking area to the eastern lip of the falls, and there's a longer trail that heads downstream a bit before heading back up and rejoining the shorter bit, making a brief loop. I'm pretty sure this spot was just below where the longer trail rejoins the shorter segment.  A spur off the longer path provides a more distant, but less obscured, view.It appears, from this post by Walter Sullivan (If Oregon […]

3:14 PM | On Rock Classification
Two interesting articles:1) In the Journal of Sedimentary Research (behind paywall) Kitty Milliken proposes a tripartite classification of fine grained sedimentary rocks, those with grain assemblages with greater than 50% of particles by weight or volume less than 62.5 µm (4 Phi). There are a number of names for these types of rock; mudstone, claystone, pelite, argillite to name a few. This classification categorizes the rocks according to the composition, thereby indicating the source of […]

9:54 PM | Geo 1095: April 21, Day 841: Shy Koosah
The forest canopy around Koosah falls is heavy, and there are relatively few spots with a more or less unobstructed view. In fact, there's only one spot I've found where one can see almost the entire cascade without some kind of foliage in the way, and it's well back from the plunge. This is a pretty good shot for this waterfall: you can get a good sense of its form, even with the obscuring conifers. However, I think my best shot is the one I'm planning for tomorrow.Photo unmodified. July 7, […]

11:06 PM | Geo 1095: April 20, Day 840:More Koosah Springs
In addition to the "parking lot spring" east of the road, there are numerous springs emerging into the gorge below Koosah Falls. As I mentioned way back near the beginning of the Geo series, "I spent more time gazing at these than looking at the falls themselves." We're looking over the eastern lip of the falls here; as you can tell, this isn't the best spot to view the falls themselves. There are a few spots downstream (south) with better views, but the thick forest foliage makes these falls […]

9:32 PM | Geo 1095: April 19, Day 839: Koosah Parking Pool
The previous entry in this set was looking more closely at the spring emerging in the bottom  middle of this photo. But looking up and generally south, it's a very pretty forest pool. While not exactly hidden, it's not exactly obvious either. It's easy to spot if you look for it, but there is a narrow line of trees and brush between the parking area and the spring. Furthermore, the attraction here is Koosah Falls, which lies in the opposite direction, to the west. So the natural […]

4:43 PM | Siren Call: Sea Lions at Craven Rock
When I fist saw this glacial erratic off the east shore of Marrowstone Island I thought it might be a layered sandstone. However, before I got close enough to see it better I could hear it. The slopes of the giant boulder are just right for hauling out and enjoying some sunshine. Craven Rock with bluffs of the west shore of Whidbey Island and Mount BakerThe erratic is at least 40 feet across based on high resolution aerial photographs. The rock is about 400 feet off shore. As such this […]

11:25 PM | Hill Road South of Coupeville
On returning from ventures on the Olympic Peninsula via the Port Townsend to Keystone Ferry I often take a slight detour from the more direct route. I turn off of the main road, Engle Road, onto Hill Road. Hill Road turns into a narrow lane that follows the top edge of the shoreline bluff through wind blown old Douglas firs. The views open up to the west as well as curving coast line. The road follows the coastal curve and then descends to the beach.The beach has a parking area and trails […]

8:25 PM | Geo 1095: April 18, Day 838: Ice Cap?
I'm not finding a whole lot of information on Ice Cap Spring/Creek, but on our July 2013 trip, Anne pointed out this spring just east of the Koosah Falls parking area. Ice Cap Campground and Day Use Area are just a hundred yards or so south. The turnout for both the falls and camp, off of highway 126. are the same; you branch north to the falls, south for the campground. At any rate, I'm guessing this is the headwaters of Ice Cap Creek. I'm standing on dry ground here, and the spring emerges […]

“O, promised landO, wicked groundBuild a dreamTear it downO, promised landWhat a wicked groundBuild a dreamWatch it all fall down”“San Andreas Fault” Maybe the first persons to note something unusual in early morning of April 18, 1906 were the sailors on board of the “Wellington“, just entering the bay of San Francisco. The captain reported later that the ship “shivered and shook like a springless wagon on a corduroy road” even if the sea was as […]

12:08 AM | Geo 1095: April 17, Day 837: Gorge-ous
On this trip, we walked down along the gorge below Sahalie Falls, maybe a bit less than half a mile. However, I was leery about earning too much of a return hike back uphill, so I called a halt fairly quickly. The river is beautiful in both sight and sound, and it's impressive to realize just how rapidly it can incise into these recent lava flows. On the other hand, looking at its intense energy here, maybe it's not too surprising.Photo unmodified. October 9, 2014. FlashEarth Location.

2:54 PM | Landslide Setbacks Perspective
In doing some work related research associated with some policy/policy implementation I came across an email within a public document from Jon Koloski. I have been working to purge the concept of standard buffers from landslide hazard regulations or what I prefer to call setbacks so as not to confuse landslides with wetland buffers. It was nice to see another like minded geologist on the matter."There is not any definitive science that supports a prescriptive buffer of any dimension […]
