Environment and Location
The Tehuelche lived in Patagonia between the Negro River and the Strait of Magellan. Although they tended to favor certain territories, their range was actually quite fluid, which makes it difficult to precisely define Tehuelche boundaries in terms of rivers or other geographical features.
The Patagonian climate had a highly variable temperature range, both between summer and winter and day and night. The average winter temperature was -2ºC and summer highs could reach up to 40 ºC. It was a land of volcanoes and steppe, with broad plains that were home to a rich variety of animal life.
