I love that I have enough background now to grasp not only what an expert like Skye is talking about, but even occasionally what he's hinting at. Nick has opened up a whole world to me. His approachable style makes learning complex topics almost effortless. This lesson from Skye was so interesting and enjoyable. I wish I could be there, even with the cow smell!

Clarification: I think I used Wisconsin instead of Pleistocene or mistakenly said 150,000 yrs - Please excuse, I was very tired after spending more than a week in the field. Also, unconformities Richard Waitt and I observed at the Rulo Site in northern Walla Walla Valley, described by Professors Nick Bader and Pat Spencer of Whitman College (Bader et al., 2016), are likely older than last glacial (>75 ka). My comments were unclear regarding their work. Each of the Rulo unconformities is separated by roughly 100,000 years. Strata there could plausibly correlate to the calcretes near Othello.

The last time I stopped in Othello, I was in high school. It was the mid 70’s and my team was playing against Othello High School in the WIAA state football playoffs. We won the game on the efforts of my neighbor who played fullback and ran for over 200 yards in that game. It was a great game and the kids from the home team were just as enthusiastic as our fans. Truly the best experience a kid can have in high school is playing under those Friday Night Lights!

I am fully convinced that during the 1950's America's top geologist, Professor Zentner (not his real name) was called to area 51 to look at the geology around the area where I was told by someone high up that they ran experiments. Professor Zentner was pulled into a time warp and now spends his days looking at the local geology of Washington but he knows so much more!

I wish we had someone, like you Nick, here in the coalfields of southwestern West Virginia and eastern Kentucky to help make some sense of our unique geology; with the many coal seams, sandstone, shale and limestone layers. It’s truly amazing and baffling to me, as a lifelong coal miner and one who always has been in awe of our precious earth and how it all came to be as it is

Thanks for this one, Nick! I like that Skye Cooley gravitates towards these kind of “liminal” subjects in geology-it seems like he enjoys working in between and on the edges of the familiar, both expanding and further connecting the body of knowledge of PNW geology. Paleosols and pedology doesn’t get nearly enough attention in geologic education, IMO. Besides calcrete, there are all kinds of hard pans or “duricrusts”, like silcrete (silica rich hardpan/duricrust), gypcrete (gypsum rich), ferricrete (aka laterite), alcrete (basically bauxite), and other “orecretes”, or super gene ore deposits. I’m interested in these Plio-Pleistocene older floods. There were many Ice Ages before the most recent, and the newer floods likely wiped out flood deposits from older floods, which would have traveled along similar paths, so it’s no surprise that evidence is scanty. Besides the Ice-marginal story, with the Missoula floods, there is of course also Lake Bonneville and the Bonneville flood, and many other huge lakes existed in the PNW during Plio-Pleistocene time. I think the idea of the river competing with the volcanic pile is smart, though. Volcanics dam river, river incises volcanic pile, outburst flood results, leaves a fossil surface as a high and dry grassland (or sagebrush land), where it just bakes and accumulates carbonate for hundreds of thousands of years. It would be interesting to correlate these horizons with the glacial cycles and the Milankovich cycles that controlled them, since the formation of these calcretes depends a lot on climatic conditions.
@AvanaVana2 жыл бұрын
I want to clarify in this earlier comment of mine that by “many ice ages”, what I really meant was “many stadials” or “many glacial advances”. Technically the entire Pleistocene can be considered one Ice Age altogether, within which have been several cycles of stadial (cold period/glacial advance) followed by interstadial (warm period/glacial retreat), and many scientists even push the date of the current overall ice age back from the start of the Pleistocene to around 35 Ma, when the Antarctic ice sheets started to grow. Still some others refer to the Pleistocene ice age and Antarctic ice age as two separate, but consecutive ice ages. But again, my comment relates to the many separate stadials/glacial advances during the Pleistocene…not actual, proper ice ages. The Earth has, however gone through many proper Ice Ages too, also known as “glaciations”, or “icehouse climates”, as opposed to a “greenhouse climate”, in which there is no ice at either pole. Previous ice ages include the Archean Pongola glaciation, Paleoproterozoic Huronian/Makgenyene glaciation, the possible-but-scant-supported Mesoproterozoic King Leopold Glaciation, the controversial Tonian Kaigas glaciation (our own Mike Eddy, who many will be familiar with on this channel has in fact helped to publish the latest supporting evidence for this event, which has been challenged by many Precambrian glaciation experts), the famous Cryogenian Sturtian and Marinoan “snowball earth” glaciations, the Ediacaran Gaskiers and Baikonurian glaciation (the latter extends just into Cambrian time, and may be labeled with the more old-fashioned “Infracambrian” or “Vendian” time periods), the Ordovician Hirnantian/Andean-Saharan glaciation, and of course the Permo-carboniferous Karoo/Late Paleozoic Glaciation. There is also increasing evidence for occasional Mesozoic icehouse events or “cold snaps”, though the scientific community has not gone so far as to label these as proper “Ice Ages” quite yet…these seem to have occurred sporadically throughout the Mesozoic, namely during the Late Pliensbachian, Bajocian-Bathonian, and Tithonian epochs of the Jurassic, and the Valanginian-Hauterivian and Aptian-Albian epochs of the Cretaceous. The evidence includes possible glacial tillites, dropstones, and glendonites (cold water carbonates), nannofossil physiological changes, oxygen isotope data, and even purported glacial scour marks. So, yes-the earth has seen many ice ages, but within an individual ice age, there are many cycles of stadials (cold periods, glacial advances) and interstadials (warm periods/glacial retreats, like the interstadial during which we currently live, even though we still live during an ice age, overall), governed by perturbations in the earth’s orbital characteristics with regard to the sun (see: Milankovitch cycles), and it was to these repeated stadials/glacial advances of our current Ice Age that I was referring in my comment.

Most unusual is the white purity/absence of iron oxide, even less than 1% of FeO stains anything brownish/yellowish after firing, rather firing Calcrete above 1200ºC a pure pale with greenish granular tones emerged. Also shocking how the Othello Calcrete is exactly identical from my local Barcelona: pure white, cracked cemented chunks perforated with roots and insect action, only my road outcrop was several meters high of uninterrupted Calcrete on top of a 177 meter deltaic mountain.

And I swear I could smell the smoke coming off Mr. Cooley's brain as he's trying to sort a complex picture into a paper to publish.

I grew up in Yakima and Selah. We had a small ranch with open pastures. We wanted to raise cattle, so fences are pretty important. Easy right, post hole digger - just go for it. 1-2 feet down, hardpan so hard and so thick that building fences almost requires explosives to break up the layer (we did and it worked). Next time, I will use pneumatic or electric jackhammers. Hard getting explosives now days. Funny thing is it just depended where you lived. Some areas had better soil than others. In Yakima, we had river cobble.

I'm not sure either. The lakes formed in Pasco Basin at the end of RIngold time probably didn't form by ponding against the Horse Heaven Hills, as has been said for years. The HHH and Wallula Gap appear to be older than 3 Ma. The young Simcoe volcanics near Goldendale may be the culprit. Their eruption may have swamped the Columbia Gorge, forming a dam for a while until the river cut through. Not sure. That story, first proposed a hundred years ago, is being sorted out by others right now.

I submit that calcium carbonates can form over much more rapid time periods than people realize. Many claim that stalactites of a certain size for one example, take roughly a hundred thousand years. But stalactites of similar size have been proven to form in 60 to 80 years. A VERY large stalagmite in Texas formed outdoors from a single artesian spring exiting a pipe that was practically non-existent in 1912. Now its as huge as any seen in any cave. An 1840's built limestone fort on the St Lawrence river has stalactites hanging from certain spots in the ceiling which if they were in a limestone cave in New York State would be cited at something like 9000 years. But that fort was built in the 1840's.

If the calcrete is "only" from ~ 1mya, does that mean the Saddle Mtn. fault/uplift/upthrust is < 2 million years old? Doesn't the calcrete show us that the top of Saddle Mountain was at the same elevation of the Crab Creek/Columbia/Snake/Missoula Flood valley floor and that the upthrust is just recent? Layers from bottom being Grande Ronde and Priest River Lava flows, 30 feet of Yellowstone hotspot ash, Ringgold Lava flow, with calcrete from the long stable period and Ice age flood deposits on the very top? Is that the proper concept? And THEN the uplift occurred to create the Saddle Mountain? Jimminey. Planetary evolution.
@skyecooleyartwork2 жыл бұрын
Calcretes developed atop a low-relief, low-elevation surface formed after a base level drop of the Columbia River system at ~3.2 Ma, possibly a result of the river defeating the Simcoe volcanic pile. The calcrete-armored surface has since been folded and faulted by Yakima Fold Belt structures. So calcretes would be younger than the base level drop (and post-Ringold unconformity). They are no older than ~3 Ma and no younger than ~50 ka. Young uplift of some YFB ridges seems quite possible, though they may have developed in stages. Some anticlines may have begun to form 10-15 million years ago. Pulses of uplift? Also, the Cougar Point Tuff (~11 Ma) that Nick showed us in a previous video sits today atop the Saddle Mts ridge. It was deposited and thickened in a lowland setting. The Saddle Mts ridge - at least the Sentinel Gap portion - must not have been there at 11 Ma.

The impressive north face of Saddle Mts only drops 600m to Crab Creek, a flood-scoured coulee. Calcrete-armored benches on the south side of Frenchman Hills match up well with the Smyrna Bench surface. A great view can be had along Rd 15 SW off Beverly-Burke Rd. The alluvial fill that used to span the Crab Creek valley (prior to ice age flooding) looked a lot like it does on the gently-sweeping south slope of Saddle Mts, between the crest and White Bluffs. Structurally and topographically, the wrinkle ridges are not that big. But that hike up the north face is still pretty darn tiring.

Thanks, Skye and Nick. Hey Nick, sounds like Skye is familiar with the top of Saddle Mountains. Maybe he has an idea about the brick color up top.

Guessing steam moving up and out of the wet ash bed was responsible for red discoloration at the base of the basalt flow. A slight chemistry change occurred during eruption and was later highlighted by weathering (oxidation). I bet Dr. Shamloo knows.

Milwaukee RR grade? My Dad worked for them! I’ve always thought the flood features of the scablands took many floods to create more than the most recent floods?

I don't know where Othello is, but I know where the state routes meet. 😂 My brain just did this like supersonic flyover from both directions, and crashed over where Othello would be. :50 the white rock in the middle of the screen looks exactly like what's in the exposed cliffs over East Wenatchee.

Sounds like you should talk a grad student into doing his masters here! Great walk!

If you fly the drone, are there any scales you can place before flight,; and any post production edits you could do to enhance a published illustration? It would need to be lightweight for field work. Perhaps inflatable.

Are you parked on W Herman RD for the second location, north on the tracks? I think I have found the exposure. edit: Never mind. I just found your second site map link.

I am looking at exposures that we thought were Silurian breccia. Looking in more detail we have a surface that is different to the base (this is a Silurian breccia/sandstone unconformable on Ordovician Quartzite) we think it is silcrete - which is the sort of 'soil' but is in silicaceous deposits, its silica not calcium !
