I stood next to Franz Josef glacier at the river mouth that comes out of it's face while large clumps of ice were falling off it and carried a peace of ice a mile back to the car and melted it into a class and drank it when I was 13. https://www.franzjosefglacier.com/ I've also been to the other end of it called Fox Glacier https://teara.govt.nz/en/video/10757/fox-glacier-from-the-air
