It was made by Alexander Mackenzie of the North-West Company, who, with his nine companions, arrived at this spot on the 21 st July 1793 .

Mackenzie, by observations, ascertained his position, spent the night here, and, after writing on the southeast face the words now cut therein, retraced his course to Lake Athabasca .

This transcontinental journey preceded by more than ten years that of Lewis and Clark.
