Accretionary Wedge #58: Signpost Outside of Nome, Alaska

Signs there may be gold in the area.
Signs there may be gold in the area.

I’m currently in Nome, Alaska for another season of fieldwork. So, if I’m a bit scarce around here over the next several weeks, that’s why. However, I hope to share a few pictures from Alaska now and then. Here’s one to start things off. While driving around the Nome area today, I ran across this fun signpost. I think that it is a perfect entry for Accretionary Wedge #58! Don’t forget to participate in this month’s wedge if you haven’t already.

Accretionary Wedge #58: Signs!

So, there’s  been no call  for an Accretionary Wedge geoblog carnival for July (although there is a call for August), but some folks on Twitter have suggested that I expand my signposts geomeme into a full Accretionary Wedge. Sounds like a good idea to me!

So, for this month’s Accretionary Wedge, please share a picture of a geographical and/or geological sign that you find interesting. Please submit your entries by August 1st. Two weeks should be enough time for you to share some fun sign pictures! If you don’t have a blog, feel free to email me your picture, and I’ll put it up when I compile everyone’s submissions. If you’ve already commented on the geomeme post, I’ll include your entries as well.

Accretionary Wedge #57: Seeing Geology Everywhere– The Compilation

Last month I hosted the Accretionary Wedge here at Georneys. The theme was “Seeing Geology Everywhere”, and I invited people to share stories about seeing the world through geology-tinted glasses, so to speak.

Several geobloggers participated in the wedge:

First up, Simon Wellings of the blog Metageologist wrote about how he pays attention to the accuracy (or, sometimes, the lack thereof) of the geology of children’s TV.

Next, Lockwood DeWitt of the blog Outside the Interzone compiled some links of the many, many times that he has written about “Seeing Geology Everywhere” and, furthermore, challenged his readers to find something that isn’t, directly or indirectly, related to geology.

Hollis of the blog In the Company of Plants and Rocks wrote a wonderful Geokittehs-inspired post titled Cat Tectonics.

Short Geologist of the blog Accidental Remediation shared how she often randomly stops along the side of the road when she spots some interesting geology. I think that many geologists do this. I, for one, am always keen to stop at an interesting roadcut!

Patrick Donohue of the blog Poikiloblastic wrote about how often he sees contour maps when looking at wood grain surfaces, such as the top of his desk.

Fj of the blog Effjot wrote a very impressive post about hydrogeology and coffee. I think you may need to have a cup of coffee before you can tackle understanding those coffee equations!

Silver Fox of the blog Looking for Detachment wrote about how she sees geology in patterns everywhere— from floor tiles to clouds.

Last but not least, David Bressan of the blog History of Geology writes about a geologist’s gravestone.

Thanks, everyone, for participating!

I’m hosting this month’s Accretionary Wedge. For those of you who don’t know, the Accretionary Wedge is a monthly geoblog carnival which is hosted by various geology bloggers. The host proposes a topic and everyone– from amateur to professional geologist, from brand-new to seasoned blogger– is encouraged to post on the topic. If you have a blog, write a post on this month’s topic and then put a link to the post in a comment below. If you don’t have a blog, feel free to email me your entry (georneysblog AT gmail). Please send your entries through by June 20th. I apologise for the short deadline, but I’d like to compile the posts before I leave for fieldwork in Alaska on June 24th.

Here’s the call for posts:

This month’s Accretionary Wedge topic is “Seeing Geology Everywhere.” Like many geologists, I often see geology in places where there are no rocks. I see landslides and orogenies in messy piles of papers on my desk; I see stratigraphy in my desserts and chemical diffusion in my accompanying cups of tea; I see interference colors in paintings in modern art museums.

My geology vision, so to speak, is heightened when I am especially excited about a geological subject– and when I am working long hours on a geology project. For example, back in 2007 I participated in a 50 day long research cruise along the Ninetyeast Ridge in the Indian Ocean. I worked long shifts describing the rock samples that were dredged up from the ridge. One evening after a particularly long shift, I was brushing my teeth before bed and found myself estimating phenocryst percentages in the speckled linoleum tiles on the bathroom floor.

One (in)famous example of geology vision is Geokittehs, a blog about geology and cats that I started with my friend Dana Hunter two years ago. Yes, for two years I have regularly written a blog about geology as shown through cats in various poses. If that doesn’t qualify as “Seeing Geology Everywhere” I don’t know what does!

Now it’s your turn: Do you see geology in unexpected places? Do you often find yourself viewing the world through geology-tinted glasses? Do you have any adorable cat pictures that could be used to illustrate geology?

Please participate in this month’s Accretionary Wedge! I look forward to reading your entries.

Finally, I think we need some volunteers for future Accretionary Wedge hosts. If you’d like to host, please leave a comment below, and we’ll make the necessary arrangements within the geoblogosphere community.

Accretionary Wedge #50: Camel Sunrise

I have the honor of hosting Accretionary Wedge #50 here at Georneys. The topic I chose for the September (Deadline: October 10th) Wedge is:

Share a fun moment from geology field camp or a geology field trip. You can share a story, a picture, a song, a slogan, a page from your field notebook– anything you like!

I have many fond memories from Dartmouth’s geology field camp (called “The Stretch”) in the Western USA and also from various geologic field trips I’ve taken over the years. However, for Accretionary Wedge #50 I’ve decided to share a moment from some fieldwork I did in the Sultanate of Oman for my PhD thesis research.

I participated in two ~1 month long fieldwork seasons in Oman: January 2009 and January 2010. For the first field season one of my PhD supervisors came along to help me with mapping and collecting samples. For the second field season neither of my two PhD supervisors were available to help me with my fieldwork, so I had to recruit another helper. I ended up bringing along my husband Jackie, who was my fiance at the time. Jackie was already working full-time as an industry geologist, but fortunately he had accumulated significant vacation time from several months that he spent at sea and in the field. So, Jackie cashed in 3 1/2 weeks worth of hard-earned vacation time… and then spent his vacation helping me do more geology work!

Jackie and I worked hard during the field season. We worked long days, eating a quick campfire breakfast of oatmeal with tea or coffee and then heading off to the day’s sampling location. We would map and sample until a couple of hours before dark and then head back to camp. Even though January is the middle of winter for Oman, the days were often sunny and hot. Temperatures in the 90s were not uncommon, and we had to be careful to keep our heads covered and stay hydrated. We usually drink plain water when hiking, but working in Oman is so hot that we frequently mixed Gatorade powder into our water bottles as the electrolytes seemed to help prevent dehydration. We usually arrived back at camp a little before sunset. Some nights we arrived at a new campsite and had to pitch our tent and set-up the rest of the camp. Other nights we returned to a campsite and just had to help make dinner. Most nights we joined up with a group of scientific colleagues who were working in similar field areas. A few nights we camped on our own and made a small makeshift meal, generally out of canned supplies that were perhaps supplemented by a few local ingredients from a nearby town. No fresh food stays fresh for very long in 90+ degree temperatures. We ate plenty of canned hummus and tahini, that’s for sure!

My PhD fieldwork in Oman mostly went smoothly, but there were some challenging days. During my first field season in 2009, we experienced a rare torrential downpour, and our hotel in Oman’s capital city of Muscat flooded. We had to dart around our rooms picking our bags and other gear and putting them on top of beds and sofas as the floors turned into rivers. I remember walking down the hotel stairs to inform the hotel management about the flood and feeling as if I were climbing down a waterfall. There was no need for me to inform the management– they were already rushing around with mops and buckets and trying to placate several disgruntled guests. During the 2009 field season we also had problems with goats invading one of our campsites. One of my scientific colleagues gave a half-rotted apple to one adorable goat that wandered into our camp, and within a few minutes all of the goat’s friends arrived– more than a dozen friends! The goats started eating through the cardboard boxes that contained our vegetables and fruit, eating the cardboard along with the food!

A rare Muscat rainstorm. This storm was in 2010, but we experienced a similar storm during the flooding event of 2009.

Jackie and I had a few challenging days during the 2010 field season, too. One morning we were packing up our tent when suddenly Jackie jumped away from the tent and screamed. I asked him what was wrong, and he replied, “There’s a spider under the tent fly.” I rolled my eyes and asked, “Is that all?” Then I looked under the tent fly and started screaming myself. Underneath the tent fly was an enormous camel spider. Now, I knew that camel spiders are relatively harmless: they aren’t poisonous, and accounts of them attacking people are mostly urban legends. In fact, they aren’t even spiders; they are solifugae.  There is actually a variety of poisonous spiders, scorpions, and snakes in Oman, so camel spiders are really the least of your worries when camping in the Oman Mountains. However, camel spiders are very large and can run very fast, and for some reason this makes me– and I guess also Jackie– petrified of them. Eventually, we managed to gently coax the camel spider away from our tent with a stick. After carefully checking the rest of our tent for other critters, we packed up camp and started driving to our next sampling location.

Towards the end of the 2010 field season, we had a couple of very difficult days. One morning, I woke up and felt horribly ill. I think I must have caught some sort of flu. I don’t think it was food poisoning because I hadn’t had anything to eat or drink that was out of the ordinary, and no one else in our group fell ill from the food that we shared. Whatever I had, I was very, very sick. I immediately vomited up any food or water. All day, I could only keep a few sips of Sprite down. I left a certain public bathroom in a certain little Omani village in a terrible state. One day, I must go back and do something nice for the village– maybe donate a sparkling new public bathroom. By the end of the day of vomiting, I was becoming dangerously dehydrated. Jackie ended up driving me to a rural hospital, where a kind doctor treated me for free. The doctor did ask if perhaps I were pregnant with another child and experiencing morning sickness (note: Jackie and I have no children; I guess he thought Jackie and I were old enough to have a couple of kids), but once we assured him that I was not pregnant, he diagnosed me with flu, rehydrated me, and gave me some medicine to take back to camp. After a day or two I felt much better, just a little bit weak. However, I can’t say that I’d like to repeat the combination of having flu and camping in hot weather anytime in the near future!  Poor Jackie ended up catching my “death flu”, as we called it, a few days later. However, I didn’t feel too sorry for him because he had “death flu” in the nice air conditioned hotel room with a proper bathroom in Muscat.

However, there were also plenty of wonderful field moments during the 2010 field season to make up for the challenging times. I wanted to share one moment in particular: a camel sunrise. As Jackie and I were driving out of camp early one morning along a dirt road, we stopped to observe four camels in the distance. As we stood by our Land Cruiser, the four camels slowly walked towards us and came over to say hello. We pet all of the camels, and a juvenile camel was particularly affectionate. After awhile, the camels continued on their way, stopping now and then to nibble on Acacia trees as they shuffled along. I have a vivid memory of the few minutes we spent watching the camels– the early morning light was beautiful, and for that moment all the world seemed to contain were the two of us, our Land Cruiser, the camels, and the mountains. In a busy, often crowded world, I’ve learned to treasure such moments. It was one of those moments that makes you remember why you became a geologist. It was one of those moments that makes you remember why you keep going into the field–  floods, goats, camel spiders, “death flu”, and all.

...And Closer...

Accretionary Wedge #50: Field Camp / Trip Moments

Ron Schott recently reminded me that I am hosting September’s Accretionary Wedge geoblog carnival. Sorry for the late posting, but quite honestly I forgot that I was hosting this month! Fortunately, I’ve thought of a fun topic, and the deadlines for the wedge are somewhat fluid. I’ll make entries due on October 10th.

Here’s the topic:

Share a fun moment from geology field camp or a geology field trip. You can share a story, a picture, a song, a slogan, a page from your field notebook– anything you like!

I think we all have many fun moments from geology field camp and trips. Feel free to share more than one, if you want! Here’s a few field camp and trip moments which I shared on Georneys in the past:
The Cow Game
Field Animal Favorites
Ternary Personalities
How Not to Lose Wireless GPS Receivers

Accretionary Wedge #42: Countertop Geology

My friend's front entryway in Abu Dhabi. Can you spot the xenolith?

Ian Saginor of the blog Volcanoclast is hosting this month’s accretionary wedge, and this month’s theme is countertop geology!

Here’s the call for posts:

Have you seen a great countertop out there? Sure, everyone says it’s “granite”, but you know better. Take a picture, post it on your own blog or send it to me and I’ll post it for you. Do you think you know what it is or how it was formed? Feel free to include your own interpretation and I’m sure others will enjoy joining in the discussion. Ron Schott suggested that we expand the entries by including any decorative stone material that has been separated by humans from its source. This includes buildings, statues, etc. There’s a lot of really unusual stuff out there, so make sure to find a good one.

I think this is a great topic for an accretionary wedge! Anyone who has spent any amount of time with me knows that I am constantly looking at stone countertops, floors, walls, statues, and pretty much anything else made out of rock.  Actually, I just visited by good friend Karima in Abu Dhabi, and she and her husband laughed at how I inspected the walls of all of the buildings we visited. I couldn’t help myself– there is some spectacular building stone to be found in Abu Dhabi. I was particularly impressed with all of the amazing building stones used in the Sheikh Zayed Mosque and the Emirates Place Hotel. My friend Karima actually joked that when we visited the Emirates Palace hotel and ate our gold-flaked dessert, I kept looking at the floors and walls rather than enjoying the spectacular ocean and city views. However, I’m actually planning to share pictures of those two buildings in other posts. For this accretionary wedge post, I’m actually going to share some pictures of my friend Karima’s front entryway to her house in Abu Dhabi.

Karima and her family live in a lovely two-story house (with a rooftop balcony) in Abu Dhabi. In front of their house, they have lovely slabs of granite decorating their front steps and entryway. They also happen to have a dark-colored xenolith just in front of their front door! The xenolith caught my eye as soon as I arrived at their house, and it actually reminded me very much of the dark-colored xenoliths I often observe in the Cape Granite here in Cape Town.

Here are some pictures of my friend’s front entryway xenolith:

Dark-colored xenolith in granite.
And here's one with my hand for scale.

And here’s a picture of a similar looking dark-colored xenolith in the Cape Granite here in South Africa:

Accretionary Wedge #39: Geologist Barbie

Paleontologist Barbie thinks fossils are fun!

Sorry for taking awhile to post this October Accretionary Wedge. My thesis has been keeping me fairly busy recently!

Back at the beginning of October, I issued this call for an Accretionary Wedge:

Dress Barbie as a geologist for Halloween! To participate in this month’s accretionary wedge, purchase a Barbie (I think they sell for about $10) or, better yet, acquire one from a friend, thrift shop, or garage sale. If you can’t manage to find a Barbie, any doll will do! Then, construct a geologist costume for Barbie. You can recycle bits and pieces of Barbie clothing or you can make new clothes using cloth, yarn, paper… anything really! If you want, you can also find or make some props for Barbie. For example, if you want to dress Barbie as a seismologist, make her a seismometer out of cardboard. Paleontologist Barbie already exists, but feel free to make another (perhaps more realistic?) Paleontologist Barbie if you want.

Several people rose to the challenge of dressing Barbie as a geologist. For my entry, I decked Barbie out in full laboratory safety gear as Geochemist Barbie:

Geochemist Barbie thinks chemistry is fun!

Over at Musings of the Midnight Fox, Reynardo presented the fantastically dressed and adventurous  Volcanologist Barbie:

Volcanologist Barbie thinks lava is fun!

Over at Uncovered Earth, Michael presented the well-prepared and socially conscious Coastal Geohazards Assessor Barbie:

Coastal Hazard Assessor Barbie thinks taking soil cores is fun!

Over at Ann’s Musings on Geology & Other Things, Ann dressed up Barbie as a gold digger:

Gold Digger Barbie thinks finding gold is fun!

Over at In the Company of Plants and Rocks, Hollis didn’t have a Barbie but instead presented Periglaciologist Fred:

Fred thinks that playing in periglacial sand is fun!

Finally, Dana over at En Tequila Es Verdad presented Geologist Barbie’s Dream House:

Geologist Barbie thinks rock gardens are just dreamy.

Can I move in there, Dana? Those rock gardens look fantastic!

Thanks to everyone who participated in Accretionary Wedge #39. Be sure to click on the links above to view more pictures of these geologist Barbies… and Fred.

Accretionary Wedge #39: Geochemist Barbie

Geochemist Barbie prepares to make aqua regia.

Here’s my entry for Accretionary Wedge #39: Dress Barbie Like a Geologist for Halloween!

Geochemist Barbie keeps busy in the clean lab! She wears a white, full-body tyvek jumpsuit to protect herself from chemicals. The suit also keeps dust and dirt out of the lab so that Geochemist Barbie can avoid contamination of her precious rock samples.

Geochemistry is dangerous work! For instance, today Geochemist Barbie has to mix up some aqua regia (70% hydrochloric acid or HCl and 30% nitric acid or HNO3), which she is going to use to clean out teflon beakers for her next set of rock dissolutions. Aqua regia is a very dangerous chemical, so Geochemist Barbie wears long, purple, nitrile gloves, bright pink safety glasses (which are definitely *not* sunglasses filched from Beach Barbie… I swear…) , and a plastic face shield for protection. She also keeps her long blonde hair tied up in a net so that it stays out of her way and also so that it does not fall into her sample beakers or chemicals.

A closer look at Geochemist Barbie's hair net, safety goggles, and face shield.

Accretionary Wedge #39: Dress Barbie Like a Geologist for Halloween

Paleontologist Barbie.

Anne Jefferson just posted a wonderful round-up of back-to-school posts for Accretionary Wedge #38.

I’m hosting Accretionary Wedge #39 here at Georneys. Several weeks ago I shared pictures of Paleontologist Barbie, which I acquired from ebay. Inspired by Paleontologist Barbie and in honor of Halloween, this month’s accretionary wedge is:

Dress Barbie as a geologist for Halloween! To participate in this month’s accretionary wedge, purchase a Barbie (I think they sell for about $10) or, better yet, acquire one from a friend, thrift shop, or garage sale. If you can’t manage to find a Barbie, any doll will do! Then, construct a geologist costume for Barbie.

For example, if you want to dress Barbie as a seismologist, make her a seismometer out of cardboard. Paleontologist Barbie already exists, but feel free to make another (perhaps more realistic?) Paleontologist Barbie if you want.

Here are some ideas for dressing up Barbie as a geologist:

-Paleontologist Barbie
-Geochemist Barbie
-Geophysicist Barbie
-Structural Geologist Barbie
-Hydrologist Barbie
-Volcanologist Barbie
-Marine Geologist Barbie
-Geobiologist Barbie
-Climate Scientist Barbie
-Meteorologist Barbie
-Museum Curator Barbie
-Mineralogist Barbie
-Gemologist Barbie
-Geology Professor Barbie
-Graduate Student Barbie
-Astronaut Barbie
-Planetary Scientist Barbie

I’m sure there are many other possible geo-themed Barbies! If you don’t feel like submitting a geologist Barbie, a scientist Barbie would be fine. For example, you could make an astronomer Barbie. If you prefer, you can also dress up Barbie’s friend Ken or any of the other Barbie characters. I look forward to seeing your creations! Please submit your entries by November 1st. You can submit an entry by posting a comment below with a link to your blog post.

I’m going to create my own geologist Barbie sometime in the next few days. I’ll post pictures once she’s ready!
