What an AWESOME show that would be, eh?! QB] Is "here" minnesota? They played on the Pier in Seattle this summer but I didn't go cuz I don't really like big shows anymore. I'm a snotty indie-rocker. I saw them at a bar in Salt Lake a few years ago, and they blew my mind. They do an excellent audio visual show to accompany the music, sheer brilliance. Wayne Coyne is a mad genius. Speaking of Beck (I'm not a big fan), have you ever heard "One foot in the Grave?". It was his first album on K records and it's mostly folk tunes. Has the brilliant tune Asshole. "She'll do anything.... to make you feel like an asshole" Great song for when your bitter and heartbroken, not that I am right now.

That's it I'm turning off my browser. See you at 11.

Hey Muffy, here's another interesting fact about Smith. I figured this out when I was there. The basalt exposed in the gorge is younger than the Tuff. The basaltic lava flowed across a plain or Valley occupied by an ancient Crooked river and formed a hard pavement. Any river (like the crooked) that flowed over the top of the young basalt flow would migrate back and forth across the valley it occupied (like the Mississippi does today). When this migrating river intersected the contact between the outcropping Tuff and the younger basalt (think of a flat plain of basalt that surrounds an older, resistant mountain of Tuff), it would begin to erode downward through the basalt to re-establish the original base-level of the river, creating a gorge with basalt on one side and Tuff on the other.

The plant field guide that I had for a class a million years ago was more of a pain in the ass than it was helpful, I burned the stupid thing Now get back to WORK I have to feed my kids some dinner I burned a book once, it was call "The social construction of reality". God it was fucking dry and boring, and in many cases not very clever either. We used it for the first half of a class called Communication and Social behavior. I burned it in the Weber as a Halloween seance.

Wow fern, you're the queen of geologic information on the web. I never even think to look there.

I think the subject we're posting under is offensive....

I'm only kidding, sorry, it's my fault I'm here anyway. Yes there are rock and mineral field guides very similar to the plant and insect field guides. Many people buy them when taking petrology and mineralogy courses to supplement the text. In your case, since you're not taking a class they would be far more useful than a petrology or mineralogy text.

Now leave me alone, I've gotta get some f*#!king work done

Yes that's reasonable. Tuff will always be formed by an ash flow or ash fall, regardless of it's location. However, if you don't KNOW it's a tuff, it's up to you to find clues in the rock that lead you to the conclusion that it is. Whether two tuffs, say one in New Mexico and one in Oregon, formed from exactly the same type of volcano in the same type of tectonic setting is unlikely, and a far more difficult question to answer.

Muffy, tuff is a rock type that generally refers to ash-fall deposits. How hard a tuff is depends on how hot the ash was. The volcanos in the Cascades are violent belching monsters that spew hot ash more often than flowing lava. The event that formed the smiffy tuff was probably very large by modern volcanic standards (keep in mind that the ash deposited by Mt. St helens was only several inches thick close to the source) The rock in smith was probably created by one eruptive event and deposited close to the source. As ash accumulates quickly it insulates itself and retains it's heat. If it accumulates quickly enough the temperature will be high enough for it to "weld", which is why Smith Rock is hard and sharp rather than ashy and soft. The main constituent of the rock is volcanic glass (silica rich rock that cooled too quickly to form ordered mineralogy), which is fairly stable at earth's surface so it is resistent to chemical weathering in Arid environs However, in more humid environments like the west slope of the Cascades, tuff will weather and erode much more quickly. The reason you don't have good rock to climb near Eugene is probably because there are no strong, thick units (yuck that was not an intended pun) of welded tuff.

I think it most popularly applies to large eroded dishes in sandstone. It's probably a spanish word for bowl or dish or something like that. The word probably gained popularity amongst climbers after Hueco Tanks was developed (which I doubt was named by climbers or geologists but I could be wrong)

I don't think Hueco is a geologic term, if you used it on one of my tests I'd flunk you fern. And you're in grad school fern, shame on you [ 10-19-2002, 06:33 PM: Message edited by: E-rock ]

That's what Geology 101 is for The one fancy word I can think of that I used is exhumation, which means the processes that unroof (i.e. remove material from above) rocks. Exhumation in it's simplest form is merely erosion. However tectonic exhumation occurs as well which is hard to explain without drawing pictures.

Generally what contributes to the climbablity of rocks in descending order from most important to least important is: Rock type - harder rock types with stable mineralogy (at earth surface T and P) Burial depth of sediments (if sedimentary) - rocks that experienced high pressure and temperature conditions will be harder than those that only achieved shallow burial before exhumation. This is generally a function of rock age. Fracturing (is the rock pervasively and chaotically fractured, vs uniform, widely spaced fracturing, which allows large bodies of pristine rock to eventually reach earth's surface) Hydrothermal/chemical alteration - has the rock undergone intense alteration from high-temperature fluids, which change the mineralogy. Physical and chemical weathering - what are the climatic conditions that the rock is exposed in. Is the rock type susceptible to weathering easily in heavy rainfall, melt-freeze cycles, vegetative effects, etc. Luck - did everything fall into place perfectly in a location where enough topographic relief exists to climb the rock.

Climber focused geology classes eh? I don't know where the curriculum would begin. There is however an excellent article in Rock and Ice from about 5 or 6 years ago called the geology of holds. IT tells you how a lot of common types of holds and cracks form. Talks about solution pockets in limestone, and patina edges on granite face-climbs (like J-tree). It was the cover story and you may be able to find it at a used Mag shop. I decided to stay here because I'm planning a trip to the Selkirks over new-years that I can't afford right now. I know I'll appreciate it later when I've got some money in the back and I'm skiing 5000 vertical feet a day in Selkirk powder for a week. [ 10-19-2002, 05:02 PM: Message edited by: E-rock ]

Yeah, like stabbing myself with rusty, blunt objects. I'm going mad. The Flaming Lips are a band. They play sort of psychedelic art rock. They have a new album called Yoshimi Battles the pink robot.

I see you lurking . Why aren't you at the rope-up? E

I think good money Karma, comes from working hard when you've just spent (or are going to spend) a lot of money. Not that it's really Karma I suppose, just common sense. Work blows. I'm trying to make my life easier by listening to the flaming lips.

I'm here, I thought I was going to go this weekend because I had an assigment that was extended. But I spent so may hours working on my computer codes this week (only got one running) that I never put any hours in at work. So now I'm trying to make up for lost hours this weekend. I was going to say fuck work and just go (because I can do that) but I just bought two plane tickets and as my friend put it last night "you don't want bad money karma". I feel like I'm doing the right thing, but it's small consolation when my work is so boring and I'm going to be here until 9:30 tonight. I'm glad I'm not alone, but I wish I was climbing (I wasn't even going to drink at the rope-up).

ASSIGNMENT EXTENDED! WILL BE AT ROPE-UP! LEAVING TOMORROW NIGHT! WILL GIVE RIDES TO THOSE IN NEED! PM me.

If you follow Erik you might get to clean 3 or 4 pieces all day. Sure makes top-roping his leads fun.

AlpineK you F%*#ing homophobe . I thought I warned you at Pub club.

Hey chuck, It's my birthday too. Happy Birthday! Maybe I'll come out and say hello at 4:30. E
