[edit] Summary

Description

The melting Cavell Glacier dipped in its own meltwater. The glacier as well as the photographer's location is perennial ice covered by a thin layer of crumbling sand and gravel deposited in summer, hence each streak in the glacial ice denotes one year. Two large crevasses are clearly visible in the glacial ice. Some people in the distance gives you a sense of scale.
