"Voyages from Montreal to the Frozen and Pacific Ocean had been written by a Scottish fur trader, from Stornoway in the Scottish Outer Hebrides, named Alexander Mackenzie. Or more accurately, Sir Alexander Mackenzie--since King George III had awarded him a knighthood for becoming the first white man ever to cross the entirety of North America. Mackenzie had completed his voyage almost nine years earlier. He suspected that his seven-month overland journey to the Pacific was probably of historic moment, and so he had left a memorial. He had created what he hoped would be a lasting inscription on a tiny sea-washed rock near the present-day British Columbia fishing village of Bella Coola: "Alex. MacKenzie, from Canada by land. 22nd July, 1793." He had inscribed the message with his finger, using an old trappers' trick for long-duration messages, dipping it into a poultice made of bear grease mixed with vermilion powder and smearing out words that he hoped would survive the cold and lashing rains for which the Pacific coast is notorious."
