The idea of taking a sandwich to the South Pole was a joke, but Hameister waited until the last minute to go through with the photo opportunity, CNN reported.
“There's been a lot of comments on it, which I didn't really expect, but I guess it's just kind of funny,” she told CNN.
Hameister made the 37-day trip to the South Pole with her father, a guide and a two-person camera team from National Geographic. She pulled a 220-pound sled 373 miles, CNN reported.
Hameister skied to the North Pole in April 2016, becoming the youngest person to travel the 62 miles from the 88th parallel to the pole. In May 2017 she became the youngest woman to ski across the Greenland ice cap without help, CNN reported.
Now, she is the first woman to travel a new route to the South Pole, skiing by way of the Kansas Glacier of Antarctica, CNN reported.
Here is a speech Hameister made on TEDx in August 2016, which sparked some negative reaction from internet trolls.
