Gingerbread Architecture

Yesterday we decorated gingerbread houses - an Odell Christmas tradition. This was the first time we've ever used real gingerbread though. Usually we go the easier graham cracker route. Ryan and I made the gingerbread on Tuesday. We spent a good five hours rolling, cutting, and baking the dough for seven houses (one extra in case we had any disasters). It was exhausting. But it was worth it! We had some graham crackers on hand though for emergencies and for additions. I think next time we would do the gingerbread again but use graham crackers for the roofs. They're lighter and easier to perch on top of an already precarious gingerbread structure.

Michael and Ryan usually do not like to be constrained by simple house designs and usually build something unique while I stick to the tradition four walls and roof plan. Michael definitely gets the award this time for the most original "house." We dubbed his "The Church of the Flying Spaghetti Monster." He did not intend it to look like a church, but it did. The entire time the rest of us were assembling and building our houses, he was working away on designing and cutting his pieces. He didn't even get started "gluing" things together until we were all done. But we waited for him to take photos and I think it was worth it. Here is The Church of the Flying Spaghetti Monster:

Attic Improvements

Wearing my full personal protective equipment (PPE) with the new opening to the attic in the background

This my attic before I insulate, the existing insulation is flush with the joist and about 6 inches deep.

 

It has been about a year since I did any home improvement projects so I have been trying to decide what I wanted to work on.  Most of my past projects have been things that are seen and appreciated such as paint, trim, and appliances.  But this time I am taking on the unseen, the attic.

The Department of Energy recommends a minimum of R-38 insulation in the attic of existing homes with electric baseboard heat in Seattle.  My attic currently has about 6 inches of loose fiberglass insulation which equals approximately R-15.  My plan is to boost this number significantly by adding a full covering of R-30 fiberglass batts.  It is unlikely that I will recover the cost in my electric bill anytime soon, but at least I can have the satisfaction of knowing that after 65 years this house will for the first time have sufficient insulation overhead.  I have read that 60-70% of homes are under-insulated.

Once the new insulation is in place it will be very difficult to access the attic.  Today I took the opportunity to complete some prep work.  The first step was to add a new access door to the attic from the attic over the garage.  This will allow me to bring in the new insulation without having to take it through the house.  I also took time today to seal any gaps in the ceiling around wires and light fixtures, this will help ensure that I am not loosing any heat due to convection.  Finally I took on the very nasty job of brushing down 65 years of cobwebs.  while there might not be any benefit in doing this it sure makes the attic a more pleasant place to work by reducing the creepy factor.  All I need to do now is install a missing gable vent and I will be ready to insulate.

The first photo I posted is me decked in full PPE with a full face respirator.  This might seem like overkill, but I don't think so.  The existing fiberglass insulation is some nasty stuff and when you start shuffling it around it can get airborne.  I have learned from my medical training that you shouldn't take any chances when it comes to your lungs and the little alveoli that make it possible for us to breath.  Unlike our skin and other parts of our bodies, alveoli are basically incapable of regenerating thus it is very important to protect the ones you have.  I also taped my latex gloves to my tyvec suit. I was hot but I'm not itchy now.

Urban Rock Climbing

The weather has been so nice lately that my friend Ryan and I decided to take a little time to go climbing at the Mountaineers facility here in Seattle.  The Mountaineers Club owns a building at Warren G Magnason Park and has an outdoor climbing wall that is free and open to the public.  Last winter Ryan and I would occasionally head to the wall to get outside and keep our skills sharp.  This summer they added a series of basalt rock columns.

The columns of basalt are bolted together alowing climbers to get a realisitc crack climbing experience. They have bolted anchors at the top but otherwise it is necessary to use real climbing hardware to protect the route as you climb.  Ryan led and I followed up two different routes on the columns. The climbing was difficult but the pitch was not more than 35' high.

We found it amusing that the Mountaineers Club has placed an official summit log on the top stating that the elevation is 85'.  Ryan wrote that we ascended the route via "The North Dihedral".  We are considering heading back on the morning of January 1st so we can get the first official winter ascent.

Holiday Baking: Fluffy Walnut Scones


One of my favorite goodies to bake during the holidays is maple walnut scones. I got this recipe from my friend Ginny in Fairbanks after she made them for me a couple of summers ago. I have never made scones and wasn't even sure I liked them (all I could think about were the dried-out sugary $5 scones they sell at Starbucks). These scones are nothing like that. And even better, they are easy to make.

This morning when I made these I decided to alter the recipe a little. The dough turned out way too wet, so instead of rolling it out and cutting it into triangles, I had to just plop balls of dough on a cookie sheet. I was nervous because the consistency was so different than it should have been. They turned out just fine anyway - phew! This time they were WAY fluffier than they've ever been before and I'm loving it. I'm not sure if they still even qualify as a scone, but that doesn't really matter because they're delicious. So here are the directions with the original recipe and my alterations:

Maple Walnut Scones

1 cup chopped walnuts
1 3/4 cup flour
1/2 cup sugar
2 1/2 tsp baking powder
1/4 salt
6 Tbsp unsalted butter, chilled
1 egg
1/4 cup half and half - I added a tiny bit extra this time
3 tsp maple syrup (the original recipe called for 1 tsp maple extract)

-bake nuts for 5 min at 375, allow to cool completely
-combine flour, sugar, baking powder, salt, stir well
-slice butter into flour mixture, making sure each piece is coated, using a wire whisk press into butter until sandy, add walnuts
-in a separate bowl beat half and half, egg, and maple
-combine mixtures just until blended with a spoon (the original recipe says to first use a spoon then your hand, but my version this time was way too wet to be mixed by hand)
- plop balls of dough on an ungreased cookie sheet (in the original recipe, you would roll the dough out on a flat surface and cut triangle-shaped pieces out)
-bake for 15-20 min at 375F

* These scones are yummy even without the walnuts.

A 100 Year-Old Wedding Ring

My wedding ring with the engraving "F & A '11."

My wedding ring is 100 years old this year. I was lucky-enough to inherit my great-grandmother's wedding band shortly before Ryan and I were married.

My paternal grandfather's parents, Agnes Brownlee and Frank Odell were married on December 13, 1911 - one hundred years ago yesterday - in North Dakota. I had meant to write a blog post yesterday, on the 13th, but the day got away from me which is funny because I've been planning this blog post for almost a year. In fact, last winter when I realized my ring would be one hundred years old in 2011, I asked my mom to look up the date of my great grandparents' wedding.

When I started this blog post earlier today at school, I meant to save it as a draft and finish it later at home after I took a photo of my ring. Instead, I accidentally hit "publish" and the email-version went out to a few family members. Now I'm glad I made that little mistake because Carol, Ryan's mom, replied to the email and told me with amazement that her parents were also married on December 13th.  This is more than a small coincidence not only because they were married on the same date as my great grandparents, 36 years later, but because Ryan wears his grandfather's wedding ring.

I never knew my great grandparents but I know I am lucky to have a family ring. And I know Ryan was very close to his grandfather, "Pops," and was touched that is grandmother wanted him to have Pop's wedding band.

TEMA Testing on Lake Union

The Ballard Bridge - one of two old draw bridges between Fisherman's Terminal and Lake Union
Over the last couple of days at work we have been testing the TEMA on Lake Union. This is a great time of year to be out on the water testing equipment. The weather has been cold but unusually clear.  It's not hard to dress for the cold when it is not raining or windy.

Lake Union can be an extremely busy place in the summer, but this time of year there are as many floats planes coming and going as boats. Fisherman's Terminal, where we keep the Ugle Duckling, is a ghost town in the winter. We had no trouble finding parking or getting access to one of the dock cranes. It's nice to get a different perspective of the city skyline from the water and we always enjoy looking at all the work boats tied up between the lake and Fisherman's Terminal.

It was extremely bright out most of the day on the lake but I did manage to snap a few good photos as the sun was going down around 3:30.  I was amazed at how green Gas Works Park looked.  With the sail boat in the foreground it was easy to forget that this is December.

Sexist Interpretations in Human Evolution Part 1

An artist's depiction of two Australopithecines leaving footprints in the volcanic ash at Laetoli

As I prepare for my class next quarter on the human past, I'm exploring a series of themes that I plan to return to throughout the quarter - themes that extend far beyond the world of archaeology and I hope will help my students think critically about many aspects of their lives and the world around them. One of them is sexism in interpretations of our human past. One blatant example I plan to use is the trend I have noticed in documentaries on early human ancestors in which females are portrayed squatting, kneeling, or sitting while males are shown walking or running.

This difference may at first seem trivial, but when deconstructed, illustrates a broader cultural phenomenon that continually downplays the role of women in human societies, both past and present. This specific genre of examples pegs men as the drivers of the most important aspects of our evolution (bipedality and large brains) and women as passive recipients and users of these great advances. I'll use  the 2009 Nova Becoming Human series as an example. In part 1, called "First Steps," a scene repeatedly plays in which a female Australopithecine kneels with a digging stick, presumably to collect roots or tubers, another female squats down reaching for a small child in the background while two males appear to aimlessly walk through the scene. This is a common theme in documentaries that depict our early bipedal ancestors' lives.

As the title of the film implies, the topic is what set us on the path to becoming human and quite literally, when and why we began to walk on two legs. While a scene with female Australopithecines (early human ancestors and relatives which lived ~2-4 million years ago in Africa) digging roots and caring for children does seem benign, afterall, they undoubtedly did care for children and dig roots, consider the context in which the depiction occurs: in an educational film on the origins of humanity, our figurative and literal first steps. And it depicts men as the upright walkers. This is a reconstruction full of undertones of dated and sexist explanations for the evolution of bipedality, namely the idea that we evolved to walk on two legs because our male ancestors had to come out of the trees (due to climate change) and scavenge for meat on the open savanna in order to provide their mates and offspring with food. This is called the "Male Provisioning Hypothesis" and was a popular explanation for the evolution of bipedality, and even though most anthropologists now recognize that it is not the most likely scenario, it is still presented in college textbooks with little in the way of caveats. To be blunt, it's a load of crap. First, it does not explain why we ALL began to walk on two legs. Second, there is no reason to believe that there was a sexual division of labor, or even anything akin to monogamous pair bonds, several million years ago. In fact, there is evidence to the contrary. Third, meat, even scavenged, did not make up a large portion of our ancestors' diets - nor does it for recent and living hunter-gatherers. And fourth, in modern and ethnographically-recorded hunter-gatherer groups, it was women who provided the majority of the food to meet their children's needs, not men. In fact, hunting, generally a men's activity, is a famously low-return subsistence pursuit. Collecting plant resources or hunting small game, usually women's work, is a much more reliable and fruitful activity. But like I said, it is doubtful that our ancestors 4 million years ago had a social structure and division of labor anything like our own. But back to the film - I am disappointing to see a film produced so recently which still presents viewers with a picture of our male ancestors as the bipedal walkers while women crouch in obscurity. These type of depictions are not only common in documentaries, but also in artistic representations of our human ancestors, in textbooks, and even in museums. Part 1 of this series is not the worst of it, in fact, it does have some great reconstructions of females that I will discuss in another post. Part 2 of the series (also a topic for another post) has even worse gender representations though.

I could write for pages about the multitude of examples I've seen that masque sexism with realistic-seeming interpretations of past human life. I noticed this trend in films and artistic renderings when I was in college, but recently I've begun to read scholarly literature on the topic. I find it both fascinating and disturbing. Mostly I've come to realize that the majority of non-anthropologists don't know enough about currently-accepted scientific interpretations of human evolution and archaeology to view these representations of past human life with anything other than interest and curiosity. And why should they?

This is why: our view of the past is shaped by the present - by examining how we see ourselves in the past, we get a window into our present. I know that sounds backwards, but I think it's accurate. The (I assume) unintentional representations of males as the important actors in our evolution and females as simply bystanders mimics modern gender discrimination - women are rarely overtly discriminated against today but there is a vast body of evidence demonstrating that women are continually disadvantaged in our society by social norms. And the representations of our ancestors millions of years ago reflect those norms. This blog post, and those that will follow, are my attempt to spread what I know, as an archaeologist, about gender roles in our human past and to encourage other people to think critically about gender, both today and in the past.

Birthday Cake

Calla lily fondant/gum paste birthday cake

This weekend was a birthday party for our friend Brooke. I was excited to have an excuse to make this calla lily cake which I've been eying in my fondant book since last winter. This was the first time I've had to roll out the fondant without Ryan's help - I'm glad it was a small cake! I used gum paste for the first time for the flowers and leaves. I really liked working with gum past. I wasn't very sticky, rolled out easily, was easy to color, and dried pretty quickly.

What I really wanted to say in this post though, is that Brooke is an amazing person - truly inspirational. The kind of person who makes me feel like I should be doing so much more to help people who need it. Brooke teaches children in grades K-3 with emotional and behavioral disabilities. The kids in her class come from so many backgrounds, some of them heartbreaking.

This fall one of her students wrote in his back to school book that his greatest wish was that his mom would have enough food so she wouldn't have to worry. Brooke already knew about the child's situation at home and had sent him home with food from her own kitchen before, but this time she bought bags full of groceries for him. When she posted the photos of the grocery bags on facebook, she was flooded with comments of people willing to donate food to feed kids like him. From those comments she spawned the idea for a backpack program at her school where backpacks full of food would go home with needy kids on Friday afternoon and come back empty on Monday morning. I cannot imagine what it must be like for a small child to know they're not going to eat a good meal all weekend (thanks to the federal school breakfast and lunch program they can at least have two meals/day during the week) or for a parent to know they can't feed their children. And that kids like this live here in Seattle, not just in third world countries. But I know people like Brooke make a difference in the lives of these kids.

And as if that weren't enough, in her spare time Brooke fosters cats, giving them a break from the shelter and works with her horse Denali who she basically saved from the slaughterhouse in 2008.

No time wasted cutting the cake!
Can't go wrong with Hershey's especially dark chocolate cake recipe!

The TEMA

Welding the port wing of the TEMA
TEMA sitting on our equipment trailer at an angle so that it will be street legal.
Electromagnetic sensors inside the TEMA
TEMA on the R/V Ugle Duckling
We were very happy that we could raise the TEMA out of the water onto the A-frame of the boat.
A few years ago my colleague Rich and I had an idea for an improved underwater metal detection system.  We were literally having a beer and sketched it out on a napkin.  We called it the Towed Electromagnetic Array or TEMA.  Now almost three years later this idea is quickly becoming a reality.

Over the last year, between other survey jobs, we have been moving forward with our design.  I created a three dimensional drawing in Google Sketch Up, generated drawings for plastic components, researched and selected materials, and even built a 1/5 scale model.

Over the past few months I have been working intently on developing the TEMA.  This summer we purchased much of the materials, and had the larger plastic components cut to size.  The TEMA is constructed with high density polyethylene plastic and structural fiberglass.  Due to the uncertainty of the final design, we decided to complete the construction ourselves.  This meant a lot of hands-on work.  I purchased the necessary tools and taught myself to weld plastic.  It took two of us about four weeks to build.  It was certainly an evolving design and I really enjoyed the process.

The TEMA was constructed in three sections; each one 3.5 by 11ft.  Thus the final assembled product is too large to easily transport down the road.  An engineering solution was necessary.  Inspired by the hydroplane racing boats we built a mount to hold the TEMA at the 45% angle on the trailer.  In this configuration it sits 12 feet tall and 8.5 feet wide, in other words it is now street legal.

Designing and building the physical towfish is only part of the challenge.  Along the way we have been working to integrate and modifying the on-board sensors.  Being neither a mechanical nor electrical engineer I often feel like I am shooting from the hip.  There has been a lot of wiring and testing of electronics, this has resulted in me becoming proficient at soldering.

We still have a lot of challenges ahead but when we get the full system up and running it is really going to be amazing!

Partners in Environmental Technology Technical Symposium & Workshop

My poster

This year was my third attendance at the Partners in Environmental Technology Technical Symposium & Workshop in Washington DC.  The conference is about building partnerships between the Department of Defense and the private sector to develop technologies that meet strategic environmental needs for the military.  Many of the attendees at the conference have received funding through this program and are there to present their research and share ideas.


As usual we presented our most recent achievements in underwater munitions detection.  Despite the fact that marine UXO survey is only one small aspect of what we work on, we have continued to make significant progress in our ability to efficiently perform sophisticated underwater surveys.  Detecting munitions underwater is not a trivial task.  In fact, we were the only people at the conference who were presenting data from a real live underwater munitions survey.  The poster I worked on focused on our new UXO detection system that we call the TEMA.  TEMA stands for Towed Electromagnetic Array and I am sure I will talk more about that system as we continue to test it and prepare for surveys this year.

Remediating munitions from former DOD sites is a major liability for the military.  Hundreds of millions of dollars are spent each year cleaning up old sites.  The vast majority of the effort has been spent on terrestrial sites.  The “tried and true” method has been to detect and dig up every magnetic anomaly in the area to be remediated.  This is a very costly process.  Thus the holy grail of geophysical surveying has become the ability to determine if a magnetic anomaly really represents a UXO or just a piece of scrap metal.  With that ability we could save millions of dollars at every site.

The DOD has funded some researchers to do just that through the partners in environmental technology program.  There are now systems and methodologies available to almost flawlessly classify the detected anomalies as a specific UXO or scrap.  It has been amazing to watch the system work over the last few years, to watch the concepts and prototype systems be developed, tested, and refined.

One of the best things about this program is that it funds applied research that meets specific needs of the DOD.  Munition remediation is only one small part of the program.  Personally I enjoy seeing all the developing technologies related to energy efficiency.  I spent quite a bit of time talking with exhibitors about “smart electrical grids,” LED lighting, solar capture devises, photo voltaic arrays, hybrid trucks and other fascinating topics.  DOD facilities can act as full scale test beds for energy saving technology that will eventually be implemented in our neighborhoods.
