On May 31 they arrived at the confluence where the rivers now known as the Finlay and the Parsnip, flowing together, form the Peace. The Indians of this region told Mackenzie of a great river beyond the big mountains, a river that flowed towards the noonday sun; and of 'Carrier Indians'[2] inland, who acted as {78} middlemen and traders between the coast and the mountain tribes. They said that the Carriers told legends of 'white men on the coast, who wore armour from head to heel'--undoubtedly the Spanish dons--and of 'huge canoes with sails like clouds' that plied up and down 'the stinking waters'--meaning the sea. Mackenzie was uncertain which of the two confluents to follow--whether to ascend the Finlay, flowing from the north-west, or the Parsnip, flowing from the south-east. He consulted his Indian guides, one of whom advised him to take the southern branch. This would lead, the guide said, to a lake from which they could portage to another stream, and so reach the great river leading to the sea. Mackenzie decided to follow this advice, and ordered his men to proceed up the Parsnip. Their hearts sank. They had toiled up one terrible river; directly before them was another, equally precipitous and dangerous. Nevertheless, they began the ascent. For a week the rush of avalanches from the mountain-peaks could be heard like artillery fire. Far up above the cloud-line they could see the snow tumbling over an upper precipice in powdery wind-blown cataracts; a minute later would come the thunderous {79} rumble of the falling masses. With heroic fortitude the voyageurs held their way against the fierce current, sometimes paddling, sometimes towing the canoe along the river-bank. Once, however, when Mackenzie and Mackay had gone ahead on foot to reconnoitre, ordering the canoemen to paddle along behind, the canoe failed to follow. Mackay went back and found the voyageurs disputing ashore. They pretended that a leak had delayed them. From Indians met by the way, Mackenzie learned that he was indeed approaching a portage over the height-of-land to the waters that flowed towards the Pacific. One of these Indians was induced to go with Mackenzie as guide. They tramped ahead through a thicket of brush, and came suddenly out on a blue tarn. This was the source of the Parsnip, the southern branch of the Peace. The whole party arrived on June 12. A portage of 817 paces over a rocky ridge brought them to a second mountain lake drained by a river that flowed towards the west. Mackenzie had crossed the watershed, the Great Divide, and had reached the waters which empty into the Pacific.
