This vibrant piece of glass was found on a historical forge site!
💚
Certain types of bottles, particularly mineral water bottles, were made in this beautiful shade of emerald GREEN. It was a popular bottle colour in the 19th century, but was largely supplanted by the more vivid “7-up” style green in the 20th century.

Through the Total Station and What Archaeologists Found There.
💛
This YELLOW total station frames a controlled surface pick-up where our archaeologists are flagging artifacts on the ground surface.
💛
Total Stations are incredible tools for archaeologists, they measure distance, angles, and elevations that allow us to create detailed maps of our sites. Artifacts are individually and precisely recorded, preserving the context of their relationship to the site.

Look at this remarkable point, whose beauty represents the BLACK stripe on our Progress Pride Rainbow of Heritage!
🖤
This stone tool is made of black Hudson Bay Lowland chert and is probably from the Middle Woodland Period (roughly 1,500 years ago).
🖤
Archaeologists can tell when people lived at a site by identifying artifacts like this point, that are known to come from a certain place and time. We can also look at the other artifacts found in the same layer of earth and extrapolate their age as well. This method is known as relative dating (which has nothing to do with accidentally matching with your cousin on a dating app)!

Our archaeological and cultural heritage teams conduct assessments all across this beautiful province!
🤎
Spotted during a heritage assessment was a snapping turtle (Chelydra serpentina). As Canada's largest freshwater turtles, they live as long as 100 years! This sacred animal with its striking BROWN shell was found along the bank of the Grand River.
🐢
Turtles are also central to the Haudenosaunee and Anishinaabe creation stories. They are knowledge holders and teachers, and serve as eternal timekeepers, with the plates of their shells representing the passage of time.

June in Canada also celebrates National Indigenous History Month, learn more about traditional knowledge and wisdom relating to environmental stewardship at the link in the comments.

Fragments of imported ceramics are ubiquitous on historical archaeological sites. This fantastic LIGHT BLUE motif represents the final stripe of the transgender flag!
🩵
This piece is made from Refined White Earthenware which is characterized by a bright white appearance that is the perfect canvas for a variety of decorative motifs.
🩵
Our Analyst determined this piece was decorated with a transfer print. This technique involves transferring a design from an engraved and inked copper plate to a thin piece of paper that is then draped onto the ceramic vessel. This method can be used to make many different types of detailed, intricate designs, that can be easily mass produced.

Pink! This delightful pink mailbox and charming house behind it are one of many gingerbread cottages along the Grimsby shoreline.
🩷
The Grimsby Beach area was a Methodist Campground in the mid-19th century. Transforming into year-round habitation with cottages built between the 1870s and early 1900s.
The modern bright colours of the historic gingerbread cottages have given these homes the name, “The Painted Ladies”.

Today is the start of Pride Season in Canada! A fantastic time of year where we celebrate the 2SLGBTQI+ people who work at ASI, who are in our community and whose heritage we engage with.
🤍
The first colour of the progress flag is WHITE.

Pictured here is the historic Monkland Mills, nestled along the banks of the Grand River in Fergus, Ontario. Also known as Wilson’s Mill and now St. Andrew’s Mill, the original structure was built in 1856 and was rebuilt after a fire in 1886. With its striking white façade, this building stands as a reminder of the town’s milling heritage.
