Alexander Mackenzie's Explorer Diet: Pemmican, Game & Grit

Sir Alexander Mackenzie (1764–1820), the first European to cross North America north of Mexico (1793), survived on a high-calorie, locally sourced, opportunistic diet during his epic canoe and overland journeys for the North West Company.

Core Staples

• Pemmican: The ultimate voyageur fuel—pounded dried meat (bison, moose, caribou) mixed with rendered fat and sometimes berries. Calorie-dense, non-perishable, portable. Made by Indigenous women; traded at posts.
• Wild Game: Daily hunting by engagé (crew): bison, moose, elk, caribou, deer, bear, beaver, waterfowl. Fresh meat prevented scurvy (vitamin C in organ meats).
• Fish: Whitefish, trout, pike, sturgeon from rivers/lakes—netted, speared, or angled. Critical when game scarce.

Foraged & Traded Supplements

• Berries: Saskatoon (serviceberry), blueberry, raspberry, cranberry, chokecherry—eaten fresh, dried, or in pemmican.
• Roots & Greens: Wild onion, camas, biscuitroot, cattail shoots, lamb's quarters—gathered by Indigenous guides.
• Mushrooms: Morels, puffballs—identified by knowledgeable companions.
• Maple Sugar / Syrup: Tapped in spring (eastern routes).

Trade Goods as Food

• Cornmeal / Hominy: Traded from agricultural nations (Mandan, Hidatsa, Ojibwe). Made into rubaboo (thick porridge with fat).
• Wild Rice (Manoomin): Harvested in Great Lakes/Upper Mississippi—high protein, cultural keystone.

Beverages

• Tea Substitutes: Labrador tea (Rhododendron groenlandicum), spruce tips, juniper, mint—boiled for warmth, vitamin C, morale.
• Alcohol: Rum/brandy (rationed, high-status); sometimes traded for furs.

Logistics & Adaptability

Mackenzie's journals reveal constant caloric anxiety. Caches were pre-positioned; starvation loomed if game failed or ice blocked rivers. Success depended on Indigenous knowledge—guides, hunters, processors, and maps. The "explorer's diet" was really a collaborative Indigenous food system that sustained the voyage.
