The Green Lakes Valley has been studied at NWT LTER since the 1980’s. Long-term data suggests that changes in lake and stream chemistries are influenced by a combination of glacial melt and other exogenous factors

Arikaree Glacier is located atop the NWT LTER Green Lakes Valley. Since the early 2000’s the glacier has become noticeably reduced in size. It’s predicted that the glacier will have vanished within the next 20 years resulting in significant changes for the surrounding ecosystem.
