A biface is a stone tool that has flakes removed from both sides. It can be used as a knife, scraper, or further worked into a more recognizable tool. The typical biface shape is an oval with slightly pointed ends. The biface on the left was found near Fort Vermilion in 2016.

Deep testing

There are times when a shovel just won’t cut it. Some areas have high potential for deep sedimentation. When this occurs archaeologists will turn to other methods to look for sites and for buried paleosols. In this picture Kurt is about to monitor a backhoe while it digs a trench for us to examine. The end result is a long deep tench like the one pictured here.


Autumn colours

The leaves are quickly changing their colours into their beautiful fall reds, yellows, and even browns. This usually marks our annual crunch as we try to complete all our fieldwork before the snow falls! Here Alex is testing out a site we found for Alberta Plywood in the Marten Hills, near Slave Lake, AB.

Noxious Weeds

More than archaeology…

In addition to looking for historic resource sites when in the field we are always on the lookout for noxious weeds like these oxeye daisies. When we encounter them we report them to our clients so they can manage them appropriately. In this case the client requested that we pick them out by the roots so they could spray the area with herbicide before they went to seed.

Helicopter Access

On occasion accessing our target areas is simply not possible by truck, ATV, or foot.  At least, not in a timely manner!  So bring in the helicopters!  They certainly bring a whole new perspective to the topography, and how our small target areas fit into the general landscape.  This particular project was for AlPac, up in the Conklin area.

The King of Spades vs. the Grizzly

Over the years archaeologists have adopted technological advances from other disciplines. In the office, using programs such as QGIS along with LIDAR and other data sets we can create models to predict sites. In the field, we use a GPS for navigation and iPads to take our notes. Artifact processing has also seen many advances helping us to date and source artifacts.

For all of these advances that have been made in the field, certain tools remain the same. One of the most essential tools that we use in the field is a shovel. I know many people associate trowels and fedoras with archaeologists, however these are most commonly used in academic excavations. While in the world of CRM the trowel will be used for certain situations, the shovel reigns, specifically at Tree Time it is the King of Spades.

The reigning king

The advantages to the King of Spades are its durability and its ability to cut through roots. The all metal shovel has never been broken by a staff member at Tree Time. Maybe lost forever in a deep stream when accidentally dropped… but never broken. In addition, the sheer weight of the shovel can help pound through roots. Other shovels are not as durable, the blades may warp, and they are more prone to breaking at the shaft break. Not the king though.20160519_153950

The Grizzly Challenger

Most shovels are not made of all metal but incorporate bits of wood. There can be a wide variety in quality so we highly recommend the Grizzly. These shovels are much lighter and easier to sharpen. The durability of the King of Spades comes at a cost, it is by far the heaviest and the most difficult to sharpen due to its thick blade. The ability to sharpen the Grizzly easily due to the thinner blade helps us maintain a sharp edge in the field to cut through roots. The light weight also makes them a lot easier to hike a long distance with, making for a much more pleasant hike.20160519_153703

In the end the durability of the King of Spades wins the favor of most of us at Tree Time. In fact five out of seven archaeologists, well at least at Tree Time, agree that the King of Spades shovel is the preferred tool. Long live the king.

This would not have happened if Madeline had the King of Spades!
