Map of a canoe route from the mouth of Rock or Grease Mountain River to the Great Indian River flowing to the sea and known only to the Esquimo
1 map : ms., on linen ; 139 x 25 cm.
30 July 1893 [i.e. 1892]
Shows a route to the barren lands beginning on the north shore of Lake Athabasca, near the mouth of the Grease River and going north as far as 'Rabbit Mountain Lake' and 'Indian River 1 mile wide flowing to the sea'. This is probably a route that leads north via Great Slave Lake to the Arctic Ocean.
"Title and date from map, supplied by J.B. Tyrrell."
"Andrew is identified in J.B. Tyrrell's 1892 field notebook, entry for July 30, as a Chipewyan from the Fond du Lac region. He may have been one of the group who assisted the expedition with the first portages to Black Lake."
"Outline map in red and black pen on linen, drawn by J.B. Tyrrell, transferring the information from the original version of the map, sketched in pencil on paper; place names supplied by Tyrrell."
"Note following title: The distance from the mouth of Grease River to Rabbit Mountain Lake is greater than to Fort Chipewyan, in a direction N 35 W (mag). It takes 7 days rapid travelling with canoes to reach the lake. The course is through a series of lakes between which are 45 portages in all. The Indians generally take 20 days to go and return. From Rabbit Mt. Lake a large stream flows into a great river which empties into the sea. My informant had been to this river but had never descended it."
Forms part of the 'Geological Survey maps' sub-series.
