I'm helping to build an exhibit about common rock-forming minerals. The entire exhibit has been translated into Spanish by a professional translator, but one phrase was missed (wasn't sent). Can you give me a translation for the phrase "Earth's Building Blocks"? [more inside]

I'm considering attending the Geological Society of America conference this October in Vancouver, BC. I'm an undergrad geology student, and a student member of GSA. I'm not making a presentation, receiving an award, or bringing a poster. Do people ever attend conferences like this for fun? Or would I end up feeling like it was a waste of time and money, attending a conference that really wasn't intended for people like me? [more inside]
I expect this will turn out to be something akin to a lump of interesting concrete, but please take a gander at this object from a beach near Port Townsend, Washington, and tell me what you think it might be. [more inside]
I'm hoping to get some thoughts from the green about the possibility of getting a cottage located on a cliff. The question is about fears, rational risk assessment, and Ontario Geology. [more inside]
I have seen photos of this type of rock on several Appalachian Trail blogs and galleries over the years. Two instances were in the Bland County, Virginia section.
So my mom (from Ireland) will be spending September with me in California, she's been here many times and we've covered most of the West Coast on numerous road-trips. We will almost certainly do another this time, probably about 10 days travelling down the coast from San Jose to San Diego, then we'll most likely swing east through the deserts and work our way back along the Owens Valley towards Lake Mono before crossing the Sierra back to the Bay Area. Apart from finally stopping at Hearst Castle and visiting The Getty in LA (which has been closed every other time we've been in the area). We're looking for sites of archaeological, historical or geological interest. When my mom asks about archaeological sites she's thinking things like Chaco Canyon in NM. The Google has mostly failed me, so here's hoping Mefi can do better. So I'm looking for places to visit with interesting history that are reasonably accessible, (4WD and dirt roads to get there is OK), she can walk but not hike up a hill. As a bonus question, I'm pretty interested in geology and so I'm going to go find some really old rocks (they're kinda scarce in Nor Cal) and maybe some trilobite fossils. But I'd love to hear other ideas.
This is macabre, I know. However, I really enjoy documentaries on past or future disasters: Rogue waves, wild fires, tsunamis, hurricanes, earthquakes, pyroclastic flows, etc. I often wake up at 2am, and these past/future documentaries get me calm and able to sleep again. What are your recommendations on this subject? There are so many internet sources on this material, and I've seen a lot, but please give me your comprehensive picks!
Can you help me evaluate new career directions in the Bay Area? [more inside]
I'm trying to brush up on my geology, a science that pretty much passed me by, which is frustrating when people I work with casually start talking about Cambrian this, and Triassic that. Where can I find a large poster / chart detailing all the geological epochs and periods? The chart produced by the Geological Society of America is a good start, but it would be more useful if it was, say, annotated with important events ("Angiosperms evolved here! Gondwana separated here!"), and it it had maps of the positions of continents on it at various times. Has anyone seen anything like this? My searches for geology posters have mostly turned up pictures of mountains, or "Geology Rocks!" logos...
I've been told recently that collecting micrometeorites is as easy, basically, as placing a clean surface outside and picking through the debris you collect because thousands of tons of space dust and debris fall to Earth every day. That can't be all there is to it, can it? How do you know whether you're looking at Earth dust or space dust? [more inside]

I'm visiting family and we want to know more about these rocks. What are they? How are they formed? When they break, what causes the breakage? We are in the skirts of San Jose.

Please help me come up with a clever name for my 9 year old's geology-related web site which will feature his gem and mineral collection. THANKS!

Moving to the (north) Bay Area of California: How do I best ensure that I (and my assets) survive The Big One unharmed? Eg. What should I look for in an apartment (and why), in terms of geology, design, construction, location, building codes, corner-cutting, etc. to best handle a massive earthquake? Expert or engineer advice would be great. (I'm more interested in how to find an earthquake-proof building and area, than in how to earthquake-proof my stuff once it's inside a building.)

Seeking opinions on career options and life directions for a young geologist - please weigh in with your experiences!
I'm a young geologist considering long-term career options and life directions. Please tell me about your experiences (as a geologist) in grad school, industry, or government/regulation. Or your experiences working in video/photography, as that is an alternative career path I'm considering. [more inside]

What's the proper way to order dates in geologic time when writing and why? In this example, The Iapetus Ocean existed between 600 and 400 million years ago, would it be equally correct to write 400 to 600 million years ago? Can you also direct me to a source for the rules?

Geology question: Does anyone know if there's a specific term for when mountains directly abut an ocean or sea? No beach, no shoreline, just the base of a mountain hitting up against an ocean. I feel as though I've heard of a term for this before but it's entirely possible that I dreamt it up.

I came home from Sequim Bay here in Washington with several cannon ball sized rocks I found on the beach. They had fallen from the hill-side as it eroded, leaving round capsule like depressions. They are a bit flaky and seem to be made of mud/sand that has hardened (but not like the sandstone I've seen elsewhere). What are these called? What caused them?
What are some simple experiments that help explain complicated phenomena? [more inside]
Recent research has concluded that strong volcanic plumes exhibit cyclonic, storm-like rotation, which helps explain why volcanic thunderstorms occur. The article indicates that the volcanic plume from Mt. Pinatubo in 1991 exhibited anticlockwise rotation, which I infer to be consistent with the rotation of a low-pressure system in the northern hemisphere. My question: Will the rotational direction of these volcanic mesocyclones be governed by the Coriolis Effect, local atmospheric conditions, compositional characteristics of the plume, or some combination of these factors?
