This week’s post is an update on archaeological project and site data for 2017 from the Archaeological Survey. Click the image below and zoom to see the full size infographic.
Note on archaeological sites: the site counts for 2017 are not yet final. They are constantly being updated as consultants and researchers submit their records to the Archaeological Survey. Stay tuned to RETROactive for up-to-date numbers.
Whether excavating archaeological sites or surveying the land in search of undiscovered ones, archaeologists create data. That data can take the form of field journals, artifact catalogues, GPS tracks and waypoints, photographs, excavation plans, level records, site forms, and reports. It is often said that for every month spent in the field, an archaeologist will spend a year in the lab and the office processing the field data they collected.
The Archaeological Survey (the Survey) began managing Alberta archaeological sites, research, and mitigation in 1972, with the passing of what is now known as the Historical Resources Act. At the same time, the Survey also became the official provincial repository for most archaeological data. Today the Survey collects and archives data for use by archaeological researchers, consultants, and other stakeholders, and also relies on archaeological data in order to run the historic resources management machinery.

Have you ever wondered about archaeology in your own city? Have you ever wanted to be an archaeologist? This summer an archaeologist from the University of Chicago is leading an archaeological investigation in the Mill Creek Ravine! Haeden Stewart is looking for remains from historic settlements to learn more about daily life in the early 20th century, as the city was industrializing. In the early 1900’s, the Mill Creek Ravine was home to several mills, meat packing plants, a railway line, and homes of the ravine’s workers.
Haeden will be excavating two locations this summer. The first is a shanty town located at the north end of the Mill Creek Ravine. This town was one of many that settlers built in the first few decades of the 20th century. Some shanty towns were more temporary, but some, like the Ross Acreage in Mill Creek, were more substantial and housed settlers for many years. Haeden’s team has already been working at the shanty town for several weeks, where they have unearthed some great finds, including animal bones, glass bottles, and the remains of two chickens buried in a pit!
Next, Haeden plans to excavate at Vogel’s meatpacking plant in the south end of the ravine. Vogel’s was one of three large meatpacking plants built by 1910 in the Mill Creek Ravine.
Haeden will be excavating every day of the week, from approximately 830am-530pm, except for Tuesday. If anyone is interested in volunteering to help out with the excavation please contact Haeden at firstname.lastname@example.org, or call\text him at 773-827-4004 to make arrangements.

How did people kill animals before guns and the bow and arrow? One of the oldest weapons in Alberta is called an atlatl or dart thrower. The atlatl increased in popularity around 8000 years ago and was the trusted technology for roughly 300 consecutive generations of hunters. It was replaced by the bow and arrow around 2000 years ago.
What’s an Atlatl?
The atlatl is a carved wooden board, up to 1 m long, with a hook on one end that inserts into a divot at the end of a ‘dart’ shaft (about 1 m in length).
The hunter throws the dart in a motion similar to a baseball pitch. A flick of the wrist at the end of the throw increases the speed and power. Is the use of an atlatl better than just throwing a spear? The world record for a hand-thrown javelin is 104 m while the record for an atlatl thrown-dart is 258 m! Read more →
In March the Strathcona chapter of the ASA held a flint-knapping and tool-making workshop in Edmonton. The ASA workshop allowed members to get first-hand experience making the stone, or lithic, tools that are among the most common artifacts found in archaeological sites in Alberta. Prior to the arrival of metals with Europeans in North America, First Nations people created tools such as blades, knives, axes, and projectile points, by knapping stones. Knapping technology is not unique to Alberta, but was used by humans and our ancestors in all parts of the world beginning as early as 3.3 million years ago in Africa. Today many archaeologists practice knapping to better understand the material culture recovered from archaeological sites. Knapping is also a common hobby among archaeologists and non-archaeologists alike.
Creating Stone Tools
First, cores of lithic raw material are precisely broken using hammerstones (stones and antler) to produce large, flat flakes. At the workshop, participants knapped obsidian and dacite, two types of stone that are easy to use for beginners. When knapping, safety is always top priority. Striking stones such as obsidian produces tiny shards of the material, which tend to scatter and can easily cause injury. To prevent accidents, knappers use hand and eye protection, and always have plenty of bandages at the ready. The scattered waste flakes produced when knapping are called ‘debitage’ by archaeologists.
Next, smaller flakes of stone can be worked into tools. Instead of striking the stone, smaller flakes can be removed by applying consistent force in a process called pressure flaking. In the picture below, a knapper is using a copper pressure flaker to work the edge of a projectile point.
Finally, the knappers were able to haft their new tools onto wood or antler shafts and handles. The stone tools were affixed into the wooden handles using pine pitch, and then fastened using animal sinew and hide glue. In archaeological sites the organic shafts, handles, and fastening materials have usually decayed, leaving only the stone tools behind.
Becoming a good knapper takes a lot of patience and practice, and it helps to have a good teacher. If you are interested in learning how to knap stone tools, there will be two knapping events in Alberta this year in July and September.
