Translation of the information board Crawford Lake is a unique body of water referred to as the Meromictic Lake. In a meromictic lake, the water in the lower half of the lake does not mix with the water in the upper half. This results in a condition that preserves sediments in light and dark layers at the bottom of the lake. By examining the strata, scientists can learn about changes in climate, vegetation, human habitation, and atmospheric chemistry. Crawford Lake has garnered international attention as one of ten locations (including the Great Barrier Reef, the Baltic Sea, and the Antarctic Ice Sheet) that could be used to officially mark the end of the Holocene Epoch and the start date of the Anthropocene Epoch. This marker of change is known as the "Golden Spike".
