Book excerpt: "Based on previously unpublished reports and journals thought to be lost, Through An Unknown Country provides the reader with a harrowing and riveting account of a 19th century expedition through the northern mountain ranges of western Canada. In the winter of 1874-75, Edward Worrell Jarvis (1846 1894) and Charles Francis Hanington (1848-1930) took part in an expedition on behalf of the Canadian Pacific Survey from Quesnel, British Columbia, to Winnipeg, Manitoba. It led them over the northern Rocky Mountains through what would come to be known as Jarvis Pass (Kakwa Provincial Park, British Columbia) and eventually onto the Canadian plains. The trip took them 116 days and covered over 3000 kilometres, of which almost 1500 was travelled on snowshoes. Through An Unknown Country brings together the day-to-day reports of Jarvis and the more entertaining narrative of the epic journey by Hanington into a single volume for the first time. Recounting harrowing treks through deep mountains, densely forested valleys, open foothills and wide prairie, this highly readable adventure story can most certainly be read alongside the better-known journals of Alexander Mackenzie, Simon Fraser, David Thompson and Paul Kane."--
