16 Mackenzie’s Voyages Mackenzie this was the only post in this part of the country up to 1785, While there is no definite information on the sub- ject it is generally accepted that Pond was the first white man to stand on the shores of Athabasca Lake. In 1788, Pond sent Cuthbert Grant and Laurent Le Roux to estab- lish posts on Great Slave Lake. It was during the journeys in this connection that Cuthbert Grant lost two canoes and five men in the rapids of Slave River known since as the Portage des Noyes. There is a probability that the French had been as far as Great Slave Lake before this, but whether before or after Hearne passed that way is not certain. At any rate, when the North-West Company reached it in 1786, they found there a family of French-Indian descent of the name of Beaulieu, indicating the likelihood of the presence of the French on the lake or in the district long before. Alexander Mackenzie then comes upon the scene and takes up the story of extension north and west. Up to this time no white man had been below Great Slave Lake, nor up the Peace River any distance. The Saskatchewan had been ascended by Anthony Hendry as far as the Red Deer River where he had wintered with the Blackfeet Indians in 1754-5. A French party sent out by Le Gardeur de Saint Pierre had established Fort La Jonquiére, which accord- ing to Masson was located near the present site of Calgary. The younger Vérendryes had been to a point on the Missouri near Helena, Montana, but the west and the north had yet to be pierced by a more daring adventurer. In passing, it may be mentioned that Lewis and Clarke, acting under instruc- tions from President Jefferson, followed the track of the Vérendryes up the Missouri, and crossed the divide, reaching the Pacific on 15 November, 1805. The nearest approach to the Rockies, or one equally near as that of the Vérendryes, made before Mackenzie
