The animal, nicknamed Elma, was born in what is now the Yukon and stayed close to her birthplace a decade before moving hundreds of miles west into central Alaska, the study found.
“I like to describe it as ice cream cones stacked on top of each other,” said Matthew Wooller, director of the stable isotope facility at the University of Alaska Fairbanks.
Researchers started analyzing this chemical record in the 1980s, gaining clues about how baby mammoths weaned from their mothers and how their diet changed with the seasons.
The researchers then looked at a layer formed a week before his death and searched a geochemical map for places where Kik might have been that had a matching strontium level.
“Maybe resources dried up there, and it just spent a while trying to find another preferable area to live in,” said Audrey Rowe, a graduate student at the University of Alaska Fairbanks who cut open Elma’s tusk.
After consulting with the Healy Lake Village Council, an organization of Indigenous people who live in the Swan Point region, the researchers hypothesized that early Alaskans searched the landscape for places with woolly mammoths and bison.
