Day 25: Exam Map Prep Take Two!

Today the two teams carried on a variation of their tasks from yesterday. Team Awesome surveyed and mapped the west side of Fisherman's trail, while Team Super-fantastic surveyed and mapped the area south of "the point".

Team Super-fantastic adventured into the rain forest (pictured below), continuing in the strategic formation used to find any archaeological features. It was a bit tough maneuvering through the plant life and shrubs, but Paul came to the rescue. Can you see the trees attempting to consume him in the picture below?

One of the goals of surveying south of the point was to document the locations of some of the cabins in the area, along with a large concrete pillar that was originally used for a pulley system to transport materials across they Seymour River. Max found it early in the morning!

Max was a champion today. He found window glass (pictured below), which indicates the location of a cabin in the area.

Max also uncovered an old record (see below), with a portion of the label or case! A record! That's just crazy! It was hidden under a tree stump, and originally he had overturned a very small portion of the record, and then saw that there was more of the "strange material" underneath its pine needle bed. Even though the record was not an archaeological feature, it is still useful to document because if the record has any diagnostic properties, we might be able to designate a time to the site.

Near the area with the window glass, record, and pillar, there was also a very large metal pipe running into the water. It may have been used to bring water to a cabin. There was also a similar sized pipe about 30 meters from this area.

Two very large well-shaped depressions were also found (right next to each other, and near two large piles of bricks). Paul (pictured below) was able to show us that the hole was quite deep. It would be interesting to survey this small area in the future, because of the high concentration of artifacts and features found.

Two beds (pictured below)were also found today: one was north of the point, and the other was south of the point. The metal framework and the springs were clustered together nicely, but the bed must have been very small.

Both teams (pictured below) enjoyed a pleasant lunch together in the sun.

During this whole adventure, Spencer (Tin Can Guy) was in the lab with Sonya, Sean, Brittany, and Andrea.

Spencer did some citric acid cleaning today with a few tobacco style tin boxes. The acid bath has had a few effects on the cans! The first is that once the rust has been removed, diagnostic information (previously unseen) on the labels became available. The second is that the absence of the rust seems to restore the metals pliability.

A great example that Spencer provided is the tobacco tin previously seen on Day 12's blog post. Spencer put this tin through one round of citric acid cleaning, and the difference (compared to here) is amazing! The colours are much more vibrant, and has made reading the label much easier with the improved clarity. Spencer is hoping that more will be visible after this can's second soaking tomorrow.

Tomorrow the students in the field will swap roles with those in the lab so that everyone gets a chance to have some fresh air. See you then!
