Suibel Gonzales, left, and her mother Lidia Huayllas, Aymara Indigenous women who make a living as mountain guides, walk on the Huayna Potosi glacier on the outskirts of El Alto, Bolivia, Sunday, Nov. 5, 2023. When they first started climbing the Andes peaks years ago, they could hear the ice crunching under their crampons. These days, it’s the sound of melted water running beneath their feet that they mostly listen to as they make their way up. (AP Photo/Juan Karita)
