(3,500 years), and the Taltheilei Shale tradition (2,500 years before present). Each culture has left a distinct mark in the archaeological record based on type or size of lithic tools. Great Slave Lake was put on European maps during the emergence of the fur trade towards the northwest from Hudson Bay in the mid 18th century. The name 'Great Slave' came from the English language translation of the Cree exonym, ''Awokanek'' (

), which they called the Dene Tha. The enslaved people were

tribes living on the lake's southern shores at that time. As the French explorers dealt directly with the Cree traders, the large lake was referred to as "Grand lac des Esclaves" which was eventually translated into English as "Great Slave Lake".

Suggested renaming

In the late 2010s, many placenames within the Northwest Territories were restored to their indigenous names. It has been suggested that the lake be renamed as well, particularly because of the mention of slavery. "Great Slave Lake is actually a very terrible name, unless you're a proponent of slavery," says Dëneze Nakehk'o, a Northwest Territories educator and founding member of

organization Dene Nahjo. "It's a beautiful place. It's majestic; it's huge. And I don't really think the current name on the map is fitting for that place." He has suggested Tu Nedhé, the Dene Soline name for the lake, as an alternative. Tucho, the Dehcho Dene term for the lake, has also been suggested.
