Volcanic Ramblings Part I: Teaser Tweeting

I'm now back in my sleepy little home town of Corvallis, blissfully sipping coffee at my favorite coffee shop. Bif the kitteh was clearly traumatized by his 5-day abandonment; the person who was to feed and water him and give him a little attention and company didn't, and the back-up apparently didn't really do back up. His water was low and filthy, and it looked, from the amount of food spilled around, that the bowl was filled to the brim once, then forgotten. I don't know what the whole story is yet, so I'm keeping my temper on simmer. The good news is, as frantic and scared as he was when I got in last night, he calmed and quieted down as the evening went on, and seemed pretty relaxed this morning.


While I did have wifi most nights, what I didn't have was energy and time to say anything of substance regarding the day's sights and events. So starting day 2, I made my priority to get my photos downloaded to ye old electronical difference engine, and get a few "teasers-" photos I was pleased with- uploaded to Twitter, with a minimum of commentary and concern with geological utility. I figured those things were better addressed with blog posts, which simply were not going to happen. Between the difficulty of sleeping in unfamiliar beds in unfamiliar settings, and days that invariably ran longer than anticipated, I think it's fair to say all three of us spent the trip in a state of semi-exhaustion, and complete exhaustion by the time we retired to our respective rooms.


So herewith are the photos I posted from the road, more or less in the order we visited the sites, along with the associated Twitter comments I made when posting them. I'm not going to try to resize these to larger, but they should all get much bigger if you click on them or open links in new tabs with a right-click.
Booyah geotweeps! Tired, but great geo! Few pics: 1, Salt Creek Falls, yday

Volcanclastic seds, diatomite, coal, on Rt. 97 N of Klamath Falls, ~30 mi.

Pinnacles, Crater Lake NP

in front of lahar deposit filling cut into volcaniclastic sed layers

Platy jointing 1; hammer middle bottom for scale.

Platy jointing 2, partway up Doherty grade. #1 in left middle of #2

Pisolitic texture in devitrified rhyolite (I was reminded later by that the correct name for these structures is "spherulites," however, I'm not sure "pisolitic texture" would be incorrect in this context. Any geo-terminology nerds care to clarify?)

Filling in the happy little alluvial fans- Doherty Rim

One more pic before bed: Hart Mountain (on right) from near Adel, OR.

Summer Lake: a geologist was here (before us, I mean)

Ball & pillow structure in Table Rock tuff cone deposits.

Yaaaaaay! Correlation is fun! (Table Rock tuff cone deposits)

The rarely observed "splort structure." (Table Rock tuff cone)

Palagonite tuff at Fort Rock, OR

3 episodes of palagonite tuff accumulation, 2 of sloughing into blast crater, & 1 major episode of wave erosion.

Mahogany obsidian (looks like Glass Butte) in facade of hotel where staying tonight (Budget Inn, Bus. Rt. 97, Bend OR)

Parasitic cinder cones on NW flank of Newberry Volcano, from top of Lava Butte

A few final teaser photos from last day of volcanic rambling: 3 Sisters, Paulina Peak Pinnacles & Paulina Lake

Paulina Lake, Central Cinder Cone, East Lake and obsidian flow, ringed by Newberry Caldera

Contorted flow banding in Newberry Obsidian Flow (need to measure lens cap, but recollection is 52 mm)

Flow banded block broken off and re-entrained in more flow banded obsidian, Newberry Caldera, OR.

One more: Dee Wright Observtory, McKenzie Pass, OR: a most propitious place to observe volcanoes


Keep in mind, these are intended just to be quick and dirty updates, and to tantalize various geobloggers with hints of things to come. I will post the majority of these photos again with more detailed discussion and many additional shots from the same stops and areas. I shot 625 pictures on this trip, so the above, while including some of my favorites, are truly only a drop in the bucket. Also be sure to follow (En Tequila Es Verdad), who was my impossibly generous sponsor, delightfully enthusiastic traveling companion, and increasingly, dear friend on this grueling but wondrous excursion. She probably took twice as many photos as I did. The third member of our company, Cujo359, blogs at Slobber and Spittle, and while not as enamored with things geological as Dana and I are, also helped underwrite my participation in this adventure, and showed enduring patience in the face of our lithic fixation. He has already posted a lovely picture of a rail trestle west of Oakridge OR, and will undoubtedly post further documentation of this trip in the days and weeks to come. Followup: Thanks to a commenter on that post, information on a large landslide has come to light, which Cujo359 has gone through and discussed in detail at the link. For example, mud/debris lines 50 feet up the tree trunks...


I make no promises regarding the regularity or frequency of posts in this series, but I'm looking forward to working through some first-hand experiences at long last. Stay tuned!
