Let's do flotation!
On every archaeology project we collect samples of dirt to take back to the laboratory. These can include small samples which are processed for pollen, useful for identifying plants to look at the environment or presence of domesticated plants. Soil from canals sediments can be processed and examined for the presence of ostracodes- tiny molluscs that live in very specific types of water (hot vs cold, fast-moving vs slow-moving). And other soil samples that geomorphologists study to determine environmental conditions or
The primary soil sample we collect is for flotation. We are supposed to bring back six liters of soil from features.
In the bucket.
In a 5-gallon "Homer" bucket from Home Depot I put about five inches of water in and then slowly pour the soil in.
Charcoal floating.
I use a sieve to skim off all of the charred plant materials- bits of charcoal, corn cobs, and other plant tissues.
Light fraction.
I tap the sieve onto newspaper and keep repeating, stirring the soil in the bucket to make more charcoal float to the top. When I stop getting bits, I pour most of the water through the sieve and finish with the light fraction.
I then take the rest of the muddy dirt and dump it onto a screen with window mesh and hose out the bucket. I carefully wash off the dirt and then dump the rest of the material onto a screen as well.
Heavy fraction.
There are a lot of artifacts and animal bone fragments in the midden dirt.
The green piece is olive ware from Spain. Also Native American ceramics and animal bone.
Both samples are dried, re-packaged, and eventually analyzed. The light fraction will be looked at by a ethnobotanist who identified the wood, seeds, and plant tissues. You can learn about the local environment, agriculture, and wild plant gathering this way, and examine how these change through time.
SCIENCE!

Sample from our field school dig.
I am busy processing the samples. Normally we use our fancy flotation machine, but I have to save the heavy fraction, so I have to use the bucket method.
I fill out new tags and a line on a data form first. Then cut the bag open and pour it into a red bucket that has lines telling how many liters, I write down the sample size on the form and bags.

This gets a little dusty.
I stick the hose in to agitate the water.

I visited with my barber and he trimmed my hair. He admired my mustache and suggested I apply wax to it.
I entered the Focus and drove south to Ray and Robert's house. It is like a luxury resort.
Beautiful red.
I should become their pool boy. I would faithfully rescue the bugs that land in the pool. I would have an awesome tan.
Parker kitty is friendlier in her older age. She still doesn't like to have her photo taken.
I wish I had his hair.
In the late afternoon I drove back to Tucson. Shortly after leaving the estate, a pair of deer walked across the road.
I unrolled my car window and whistled at the third mule deer to walk across the road, and it turned to stare at the human making that strange sound.
Mule deer.
It was a lovely day.
Yellow kitchen. I am covering the one wall with antique china.
Not coy koi.
They live at a higher altitude than Tucson so the wildflowers are still blooming. I admired them at 75 miles per house. At the house I was able to pause and examined the blooming cacti.

Ray and I.
Go. Away.
In a few days it is Ray's birthday so he served a delightful lunch but we forgot to sing "Happy Birthday."
Salad Caprese. The first time I had this was in 1998 in Berlin at Phillip's house.
Robert has a new job that he really likes. It shows!

Dear deer.

Lisa gave me some irises last fall and it took me forever to plant them, so I was totally amazed when one of them decided to bloom.
Purple irises are my favorite flower (pansies are my second).
I'm working on my next book, Coroner's Inquest cases of Pima County. I've typed so much my shoulder and arm are sore. OUCH.
Someone is using my picture on a straight dating website and two angry women sent me emails. I have a suspicion that the dreadful fake blogger may be bored and trying to create problems.
I'm sitting here sipping a margarita and I made it too strong!

A few things to remember:
The blue transferprinted soup tureen that I bought in Flagstaff for $24.95.
The hawk perched on the fence outside my window at work:
I really want these pants:

Cinco de Mayo at the Presidio:

Other things to remember:
- in the last week Delaware and Rhode Island achieved marriage equality (#10 and #11). Minnesota may be #12 by this coming weekend. I checked the National Organization for Marriage blog and there was closet case Brian Brown saying that same sex marriage was a "lie." Whatever that means.
- The field school students did their paper presentations. Whit has been staying at my house and it has been fun getting to know him.
- My mother turned 81 today and celebrated by getting a new roof on her house. I mailed a box of junk to her today- $40 postage. As Evan says, they are treasures to her.
- Tired of insomnia. Perhaps less caffeine?

As I work at the office, movement outside catches my eye. It is spring time heading towards summer and the babies have been let lose and are wandering about.
Ground squirrel.
I left the office right at 5 PM and a short distance up the road was a group of javelina. I have never seen javelina in the neighborhood. They were climbing out of a culvert- five adults and four tiny babies.
The littlest baby was scared to come out and cried.
Video.
Cottontail.
Cottontails are the most animal species we find at prehistoric sites. People probably hunted them in their fields, probably with snares and sling shots.
I haven't seen any Gambel's quail babies yet.
Gambel's quail.
This year the ground squirrels did not burrow under my office floor.

I took the following video, sorry about the spots that are inside of the camera lens.

I drove north to Flagstaff. I haven't been there since Evan's birthday party.
On the way.
The weather cooled down nicely.It was in the 90s in Tucson and in the 20s at night in Flagstaff.
Almost there.
Saturday, my camera batteries failed and you will have to imagine me making a chocolate cake with chocolate jalapeno frosting. We also went and saw the movie Oblivion.
This morning we procured batteries and then went to Picture Rock Canyon.
Evan and Homer.
Part of the trail is the Arizona Trail.
A grinding slick is visible on the rock.
Picture Rock Canyon is aptly named.
A thousand years ago or so, someone pecked the designs. Perhaps they were marking their territory, noting an important event, or hoping to catch some animals.
I admired the trees that were blooming.
Car on fire.
At home the cats are climbing all over me. They are locked up in the bedroom and Buddy is asleep on the carpet, snoring loudly.

I admired the tall trees.
Looking up.
I climbed up the boulders to search for rock art. Evan was below looking at pottery sherds.

Bow and arrow man, deer.
Rock art.
I wrote Rock Art in Arizona.
We went to an antique store and I noted the poor mounted bat. I purchased a photograph and a blue-on-white Staffordshire soup tureen for $25, dating to the 1860s or 1870s.
Bat.
I admired the trees that were blooming.
Cherry blossoms.
And then it was time to go home. I drove south and south of Phoenix the cars in front of me started acting crazy. Black smoke was billowing and cars were driving off to side. As I approached I could see a red car with its front engulfed in flames. It did not look like anyone was still inside it.

Twenty years ago I boarded a plane in Phoenix and flew first to Minneapolis and then to DC for the March on Washington.
I was 29, was getting ready to move to Tucson to work for the same company I work for today, was somewhat socially awkward, had some self-esteem issues.
I stayed at Laura's house and my best friend from college, Les, and his then bf stayed there as well. I think every gay-friendly house was loaded with people.
We went to the March and ended up walking with the Minnesota contingent, waiting for hours for the other states to walk by (it was chronological by when they became states, if I had waited for Arizona it would have been hours more).

Les and Homer, 1993.
It was fun, but I don't know if the march accomplished anything. I went to Senator McCain's office and talked with his gay staff member. And here it is 20 years later and McCain is still a homophobic asshole.
I look at the picture of myself, so skinny and well, cute, and think about how my life has changed in 20 years. I have a house, a handsome boyfriend, tree cats and a dog. And yet here in Arizona gay people can't get married, the Republicans and the evil Center for Arizona Policy are doing everything they can to deny LGBT people civil rights. We have a long way to go, and probably a few more marches and protests.

Let's catch up! It is spring time and my backyard is bursting out in flowers.
We then went to India Oven for lunch.
We then did some other errands- Trader Joe, Library, and Safeway. I was exhausted, but decided I needed to trim my beard for the following day's annual meeting. I had a trimming accident and ended up with a big stache.
Stache.
Buddy has been getting more exercise lately, I've been taking him on walks, carefully planning the walks to avoid all of the barky neighborhood dogs.
Buddy.
The next day it was time to dress up for the annual meeting. I am now recording secretary.
To help raise money I assembled a raffle basket of Spanish and Mexican items. I sold 63 or so tickets at $5.00 each, and the money went to help pay for the annual luncheon.
Evan arrived in the afternoon. He was coming to work on an archaeology project for my company. That night we went to Rosa's and he had the avocado enchiladas.
Evan at Rosa's.
During the week we went for walks and one time we went to inspect the nearby enormous hole, which was once supposed to be a parking structure, but now is being refilled. In the north wall of the enormous partially-filled-in hole are bricks from the Tucson Pressed Brick Company, which once operated there. A tunnel is visible, lined with bricks and with a metal sliding gate. I am guessing it was used in the firing of the bricks.
Mystery tunnel.
Buddy likes Evan, as does Snowball, which is unusual.
Mummy left for Michigan on Tuesday. It became a nightmare. She got to Chicago and then her connecting flight was cancelled. She spent the night at a hotel, and then back to the airport. I spent three hours on hold trying to get her on a flight. I discovered that Orbitz call center employees are incompetent. On Wednesday several more flights were cancelled due to horrible thunderstorms. She finally arrived at Traverse City at 1:30 on Thursday morning.
Thursday night, to celebrate, Evan and I went to Desta for Ethiopian food. It was delicious.
Ethiopian food and an excited Evan.
He left on Friday to head back north, after having an exciting archaeological adventure (he found a turquoise bead and a large decorated sherd).
This morning I was up early and salvaged some bricks for the walkway between my house and the guest house. I manage to get an enormous gash on my left palm, which I will not subject readers too, because it is ghastly and red and nasty.
And here it is 8:59 AM on Saturday and I have no clue what to do for the rest of the weekend.
Aster.
Last Saturday I loaded mother into the trusty Focus and we went to the San Agustin Presidio and watched the re-enactors re-enacting.
Allen was demonstrating flint knapping.
In the gift shop Mummy became Caroline Ingalls for a moment.
Carolyn.
Buffet.
I really like Indian food.
First plate.
