冰川曲线湖是东南极维斯特福尔山的一个冰坝蓄水池，其体积为(2 5 0±4 5)×10m，推测该蓄水池存在于S冰川晚全新世切尔诺克进动后的冰川消退时期。大坝逐渐放水，允许形成四个主要的海岸线系列，最大高度比目前22米的湖平面高24米。来自冰川弯曲湖的水溢出到下游的瓦茨湖，使那里的咸水混合、稀释，并通过埃利斯急流输送到大海。通过这种方式，瓦茨湖的水变得新鲜起来，由鹅卵石和巨石组成的冲积扇在弯曲的湖和埃利斯急流下面形成。
Abstract Glacial Crooked Lake was an ice-dammed impoundment in Vestfold Hills, East Antarctica, that had a volume of (250 ± 45) × 10 m. The impoundment is inferred to have existed during deglaciation following the Late Holocene Chelnok Advance of Sørsdal Glacier. The dam released water incrementally, allowing the formation of four major series of shorelines with a maximum height of 24 m above the current lake level of 22 m asl. Water from Glacial Crooked Lake overflowed into Watts Lake downstream, allowing saltwater there to mix, dilute, and be transported to the sea via Ellis Rapids. In this way water in Watts Lake became fresh, and alluvial fans consisting of cobbles and boulders formed below Crooked Lake and Ellis Rapids.
