Marie’s survival is noted.

One of the things that Marie’s 1814 winter journey reveals, retrospectively, is that the survival capacities she demonstrated in that winter were not new.

She had been demonstrating them throughout the 1811-1812 journey, in conditions that were also extreme, also dangerous, and also inadequately planned by the expedition’s leadership.

The winter of 1814 was the occasion on which those capacities were most dramatically tested and most dramatically vindicated.

But they were not unprecedented.
