Finlay was born in Montreal, the son of James Finlay, who was also a significant player in the western Canadian fur trade. Finlay was apprenticed as a clerk in the North West Company in 1789 at the age of 15. He accompanied Alexander Mackenzie [1764–1820] on his historic trip across the Rocky Mountains to the Pacific Ocean in 1792-93 becoming the first Europeans to traverse North America. He was placed in charge of the North West Company’s Athabasca Department in 1794, and the same year established a trading post at present-day Fort St. John, called Rocky Mountain Fort. This was the first European community established in present-day British Columbia and is the province’s oldest continuously inhabited European-founded settlement.

In 1813 the North West Company established a post on Brûlé Lake as a “provision depot with the view of facilitating the passage of the mountains through Athabasca Pass.” By 1817, Jasper House was on the west shore of the lake, according to Ross Cox [1793–1853].
James Hector [1834–1907] wrote of his explorations in January 1859:
At three o’clock we reached the point where the Athabasca emerges from “Lac à brulé,” which lies at the base of the mountains, which rise from its western shore at least 3,000 feet. This lake was swept by such a violent wind from the south that we could hardly make way against it over the smooth ice. Its eastern shore is formed of immense sand-hills; and as we reached its upper part we found the ice so covered with the same material that the dogs could hardly pull the sleds.
Frederick Arthur Ambrose Talbot [1880–1924] makes the following comments on the construction of the Grand Trunk Pacific Railway in the area around 1911:
Here and there the builders were confronted by tremendous difficulties, such as in the vicinity of Brule Lake, at the entrance to the Rockies. This sheet of water is in reality an enlargement of the Athabaska River, the southern bank being deeply indented, and the soil a light sand. The railway skirts the southern bank, and in order to preserve the grade, heavy embankment work was requisite. The remarkable feature of this sheet of water is that it is always swept by a wind which at times assumes the fury of a gale. Even at the time of my arrival in mid- summer, when the air a few hundred yards inland was oppressively still, a keen breeze played across this lake. This peculiarity is attributed to the fact that the expanse lies in the path of the funnel formed by the passage of the river through the mountains, and through this constricted channel the wind is forced to make its way like a huge draught, to expend its force upon this area of water. Be that as it may, its existence resulted in a pretty battle between Nature and the engineers, and the struggle for supremacy lasted a long time.
As fast as the sand was excavated from a cutting and dumped to form an embankment, it was picked up by the wind and driven back again. On this short length of line around the lake there are two notable pieces of work, a cutting from which 87,000 cubic yards were removed, and an embankment built up of 117,000 cubic yards. The broad, high surface of the latter suffered from the full force of the wind, which picked up the sand in dense clouds and drove it irresistibly forward into the cut. At last the engineers erected a series of screens which deflected the eddying, circling wind laden with dust, the latter falling helplessly against these obstructions, and in time forming a natural protection to the cutting. So far as the slope of the embankment was concerned, the expedient of protect- ing its surface with scrub was adopted and found to be highly successful.

Lady Anne Wentworth-Fitzwilliam [1838-1879] was the aunt of William Wentworth Fitzwilliam Milton [1839–1877]. Lady Anne married Sir James J. R. Mackenzie.
On the afternoon of [July 13, 1863] we came to a place where the trail passed along the face of a lofty cliff of crumbling slate. The path was only a few inches in width, barely affording footing for the horses, and midway a great rock has slipped down from above, resting on the narrow ledge by which we had to pass. This completely barred the way, and the perpendicular cliffs rendered it impossible for us to evade it by taking any other route. We therefore cut down a number of young pine trees, and using them as levers, set to work to dislodge the obstacle. After an hour’s toil, we succeeded in loosening it from its position, and with a single bound it rolled down with sullen plunge into the deep river, far below. We then led the horses past, one by one, with the greatest caution. The path was so narrow and dangerous, that we gave it the name of Mahomet’s Bridge.
