Allan Hills913 viewsThe Allan Hills are located on the flanks of the TransAntarctic Mountains. Ice upwells onto the hills where combinations of winds and solar insolation cause the ice to quickly ablate. Meteorites that once fell over a large region of East Antarctica have been carried by glacier motion into this small locality.

Comparison of modern satellite images with images acquired four decades earlier reveals that the dunes are nearly motionless.
