Dry season underway
As typically the case, the beginning of June marked the transition from accumulation to ablation on the Northern Ice Field. Two sensors are used to measure changes in surface height, and while one indicates less than 5 cm of ablation the other shows 20-25 cm (with the average being -11.5 cm). In both cases the decrease is more-or-less continuous through the month.
