Archaeology on Deer Mountain

On Friday, April 15th at 7 PM Tree Time Services Sr. Project Archaeologist Kurtis Blaikie-Birkigt will be presenting  at the High Prairie and District Museum on ongoing research on Deer Mountain, Alberta.  On the weekend, Tree Time will be at the High Prairie Gun & Sportsmen’s show with a display of artifacts and replicas to help identify your finds.

Early archaeological research on northern Alberta was focused on big lakes. Large campsites were found on major lakeshores and were assumed to be related to seasonal fisheries. It was assumed that past people’s hunting forays into the hills and hinterlands wouldn’t have left much of an archaeological trace. When we started doing archaeological surveys for forestry cutblocks in 2001, we didn’t expect to find very much. The typical sites we’d find would be small scatters of stone chips and flakes left from making stone tools like arrowheads. Even those sites were almost always very close to major streams or other waterbodies.

In 2005, I was part of a crew that did some pre-harvest archaeology surveys for Alberta Plywood on Deer Mountain (Figure 2). Earlier surveys had found a few sites there, more than would be expected in a place so far from major waterbodies. Even knowing there were sites there, our findings in 2005 surprised us. We found quite a few sites, they were richer than expected, included a unique local stone called Grizzly Ridge Chert (Figure 3), and we found a spear point similar in style to ones that date to 8000 years ago (Figure 1). Deer Mountain was an unusual place, archaeologically speaking, and was very eye opening to me.

Last year, I got to revisit some of the same areas for Alberta Plywood, with the benefit of another 10 years of experience, high resolution LiDAR imagery, and significant improvements in survey and site evaluation methods. We found more sites, bigger sites, and more interesting sites in places we didn’t even think to look in 2005. I came away with an even greater appreciation for how interesting Deer Mountain is, and for how much I’ve learned over the intervening years.

In this talk, I’ll touch on careers in archaeology, archaeological methods, how industry and government manage risks to archaeological sites, and a really interesting area in Alberta archaeology that’s barely been studied.

Radial Biface

Today’s picture comes from the Ahai Mneh site on the shores of Lake Wabamun, west of Edmonton, AB. This archaeological site has a long history of human occupation, from earliest hints of people in Alberta using Clovis technology, right up to the Late Precontact and Historic Periods. Featured here is a large radial biface, made of a fine-grained siltstone. This artifact was found in a field adjacent to the site, having been turned up by a plow. While not exclusive, radial bifaces such as this one are commonly associated with the Clovis tool kit, dating back to 13 000 years ago in Alberta.

Scottsbluff Point

Today’s picture comes from the Ahai Mneh site on the shores of Lake Wabamun, west of Edmonton, AB. This archaeological site has a long history of human occupation, from earliest hints of people in Alberta using Clovis technology, right up to the Late Precontact and Historic Periods. Featured here is a Scottsbluff point, made of classic Alberta quartzite. This projectile point type is part of the Cody Complex, which was present across North America between 9 000 and 7 000 years ago. Point such as this one are famously associated with large communal kills, where the hunters dispatched dozens of giant Ice Age bison in natural and built traps.

Late Precontact Arrowhead

Today’s picture comes from the Ahai Mneh site on the shores of Lake Wabamun, west of Edmonton, AB. This archaeological site has a long history of human occupation, from earliest hints of people in Alberta using Clovis technology, right up to the Late Precontact and Historic Periods. Featured here is a Late Precontact side-notched arrowhead, made of a fine-grained black siltstone, that likely dates between 1000 to 300 years ago.

End Scraper

Today’s artifact is an endscraper, a tool used to remove the flesh and hair from an animal hide. The person who made this tool took a small pebble, split it in half, and then chipped fine flakes off the one end to create a steeply beveled edge. The stone blade would then be attached to a handle, and dragged across a stretched hide to scrape the unwanted flesh and hair away. This artifact was found at the Quarry of the Ancestors site near Fort McMurray, and is made of a high quality chert.

 

Long distance trade

Featured picture this week is a bifacial knife, with fine retouch along the right margin to create a sharp edge. This knife is made from Knife River Flint, a stone material that can only be found in North Dakota, USA. Today’s artifact was found 70 years ago in Manitoba, Canada.
