Abstract: Several of Thomson's sketches of 1916 were painted in what is now known as the Barron Canyon on the Barron River. Most of these sketches are entitled as some variant of "Gorges of the Petawawa".

We previously believed that these two sketches were also from the Barron Canyon. Our present opinion is that they are from The Natch on the north branch of the Petawawa River, although some uncertainty remains.

These three sketches are not from the Barron Canyon:

Sketching locations in the Barron Canyon are within a day's travel by canoe from the Out-Side-In, but too far to visit comfortably as a day trip. These locations may also have been reachable by tote road.
The main impediment to locating Thomson's sketching locations in the Barron Canyon is that, in the modern canyon, sight-lines and the shapes of the canyon walls are often obscured by the regrowth of the forest.

The colours and lighting in all of the above sketches (with the possible exception of the second one) are consistent with being painted in early to mid October, that is, after Thomson would have been laid off from his fire ranging job. With respect to the first sketch, if the white on the south canyon walls is ice (but we don't think it is), then it is a late April, early May sketch (see Early Spring in the Barron Canyon.)
We believe that the following two sketches were painted at the Natch on the north Branch of the Petawawa River. We accept however, the possibility that they were executed in the Barron Canyon as we previously thought. These issues are discussed on a new page entitled The Natch.

There remain three other sketches whose title are variants of Petawawa Gorges. These are not from the Barron Canyon (or from the Natch). One of these remains unlocated.
