Life on the Tundra

Young Arctic Hare
Many of the baby animals on the tundra have instincts to freeze and blend with the boulders and vegetation.

Perfectly mute.  They'd be easy prey for a fox if they made a peep.
We saw this thing swimming in the river and didn't know what it was at first.  It looked like a seal, but we were 35 km inland.

It turned out it was a fox.  Not even the water is safe from this little jerks anymore.  Stay vigilant.

Wrapping up the summer

Drilled slate point 
It was a brief field season this year in Nunavut and it's all over now but the packing.  The weather is a big factor in the successes and set-backs of fieldwork and this year the rain and snow clouds cooperated with us.  We lost an hour here and there, but we didn't lose a single day to inclement weather.  The interior travel and caribou hunting sites that we worked at are notoriously shy of artifacts because they were very briefly occupied and people traveled lightly.  Still, we found a sampling of stone, bone, wood, antler, and metal artifacts to give us a glimpse of Inuit life in the area over the past few hundred years.

Taking Notes
The relentlessly pleasant weather and long field days meant there was little quiet time around camp or in the lab to reflect on the weeks as they flew by.  I haven't sorted through the photos I took and this is my first blog post since the first day in the field a month ago.  Here are a few of my favourite photos of sites and artifacts from this season.

Excavating tent rings

There were at least four tent rings at this site.

A longer piece of wood on sphagnum moss.  This site has lots of wood fragments about the right size to be arrowshafts, but nothing terribly diagnostic, so it's possible that they had other functions.

A small antler artifact with a scarfed end.

This slate point was found at a location that would have been good for caribou hunting.  It's probably an arrowhead or small lance tip.

First Day on Site

Our first site of the season greeted us with a brief shower followed by a nice bright rainbow.  By the time I took this photo the rainbow had retreated to the far side of the river, but when it first appeared it ended right on our tent rings.

The Red-Throated Loons also met us with curiosity.

Blog Post #1000

This is the 1000th Elfshot blog post and with it, I'm packing my bags in a different way.

Groswater Palaeoeskimo
Harpoon Head
I started this blog back in 2009.  Within the first couple of months I adopted the routine of publishing a new post every Monday, Wednesday, and Friday.  I liked the structured of it.  It forced me to write about something whether I was feeling it or not and sometimes the posts that I never would have thought to write turned out to be the ones that people responded most enthusiastically to.  Still, it was hard to maintain that schedule and with fieldwork and travel I would have to plan ahead and schedule weeks or even months of previously prepared posts (like this one) in order to maintain that Monday/Wednesday/Friday pattern.

On the downside, that create a lot of "filler" posts that were not necessarily on the major themes of this blog, which are archaeology, craft, and artifact reproductions.  My schedule, work, and interests change a lot through the year and when I'm working on some projects it seems like three posts a week isn't enough.  At other times it's a struggle to come up with content that is on theme and I end up posting weak or off-topic posts.

Groswater Endblade
Beginning with post 1001, I'm going to start going off schedule, but not off topic.  I don't know whether I'm going to blog more or blog less and I don't know when the next post will go up, other than it will be when I have something to say.

Thanks everyone that has tuned in so far. Hopefully I'll have some stories and photos from the field soon.

Cheers,
Tim

Same Gear, Different Pile

It's that time of year again.  The thermals and bug spray are packed and it's off to the airport to begin the long haul north for another field season.  Stay safe out there, everyone.

Atlatls and Darts for Alaska and the Yukon

Chert and obisidian atlatl darts representing finds
form Ice Patches in the Yukon and Alaska's
Northern Archaic
Here's one last look at the Northern Archaic darts heading to Alaska and the Ice Patch dart that is on it's way to the Yukon.  This project began several months ago with a request from Jeffrey Rasic with the National Parks Service in Fairbanks, Alaska to make an atlatl and dart set based on artifacts from the area.  He sent me some Wiki Peak obsidian to make Northern Archaic (ca. 5000BP) dart points from and put me in touch with Greg Hare in the Yukon to help fill in the blanks with the organic part of the tools. 
 
A simple birch atlatl and the ice patch dart
The ice patch darts recovered by Hare and his colleagues over the past couple of decades served as the models for the dart shafts.  That led to adding a direct reproduction of an Ice Patch dart to the order for Hare.  Unfortunately, there haven't been any atlatls found in either area for the time periods in question, so we decided that a simple hooked stick would be the safest way to represent that part of the kit.  As the order evolved we added a lithic production sequence showing how a dart point would be made from a core of obsidian and a second Northern Archaic dart for one of Rasic's colleagues.    

This 4-stage production sequence runs from left to right, with an obsidian primary flake on the left side of the image, through to a bifacially worked blank, a finished projectile point, and the hafted point on the far right.  The small flakes between the flake, biface, and projectile point are about 1/10th of the total number of flakes removed to advance the piece to each stage.  Conifer pitch, red ochre, and sinew were used to haft the point.
The Northern Archaic darts are hafted with ptarmigan feathers.  Modified ptarmigan feathers have been found in ice patches, although it's not clear if they were used as fletching.  We decided to use ptarmigan feathers on the darts heading to Alaska because they are from non-migratory birds, which should not have any issues crossing international boundaries.

The Ice Patch dart head is hafted into it's 182 cm long birch shaft with red ochre and spruce gum.  The lashing is sinew and hide glue. 
The middle dart is the ice patch dart, fletched with duck feathers.  According to Hare, there are a couple of different fletching methods found on the ice patch darts.  Some use whole feathers with sinew passing through the rachis of the feathers.  The earlier darts use split feathers lashed in place with sinew.  I used the split feather method, but would love to try sewing the sinew through whole feathers some day.  My one regret is that the fletching is relatively short on these darts - around 15 cm long, while Greg Hare told me that at least one of the darts was found with feathers 30-35 cm long.  To find feathers that long you'd need to use birds of prey, migratory fowl, or non-local bird species, like turkeys.  These darts needed a compromise either in the species used or the size of the fletching and in this case I went with the size of the feather rather than substituting a foreign species.  But maybe turkey feathers would create a more accurate looking reproduction. Something to consider for next time.

The Northern Archaic darts were made with foreshafts with a conical insert that fits into a sinew reinforced socket on the main shaft.  The design of these forshafts is based on ice patch specimens.

All three darts have a dimple in the end to fit the pointed spur of the atlatl.
The birch atlatls are simple and nondescript. I used the length of my arm from the tip of my outstretched finger to my elbow as a guide for their lengt.

The Northern Archaic darts flank the ice patch dart in the middle.  It's hard to photograph these things because they are so long and skinny.  The ice patch dart is a one piece dart, without a foreshaft.  It's the longer of the three at a little over 185 cm long (6'1" or so).

All done but the drying

Sinew lashings on red ochre
and spruce gum adhesive
 The Northern Archaic and Ice Patch darts and atlatls are all done.  They just need to dry overnight and I can photograph them and then put them in the mail tomorrow morning.  I'll share those final images here on Friday.   Between the various stages of lashing and drying I managed to get a couple copper riveted ulus finished as well.  Its a load off.  With two days left before the weekend and then travel north on Monday I have one small jewellery order that I'd like to at least attempt before I close up the workshop for July.  Fortunately the size and make-up of that order is a little bit vague, so if I can get anything done it will be better than nothing.

The hafted ice patch dart reproduction (right) and reference dart points collected from the Yukon.  There's a pretty wide range of point styles represented.  I tried to match some of the lanceolate forms in the bottom row.  You can see the ghost outline of the red ochre and spruce gum adhesive on the base of the points in the lower right corner of the photo.  The original image can be found in this article: The Archaeology of Yukon Ice Patches: New Artifacts, Observations, and Insights 
 
Slate ulus with spruce handles.  The two laying down have copper rivets securing the blades in place and the one standing up is tied together with sealskin raw hide.
