We have been examining Ireson Hill and found this unusual 10-15 cm diameter rock- called Passagassawakakeag !
The shape is an almost perfect Dreikanter. That’s a German word for a sample in desert or periglacial environments formed by the abrasion of blown sand. Dreikanters typically have a pyramid shape with flat wind-abraded facets.
This blog is a record of my experiences and work during the Mars Science Laboratory mission, from the preparation, landing on August 5th 2012 Pacific Time, and onwards... I will also post updates about our other Mars work on meteorites, ExoMars and new missions. You can also follow the planetary science activities with @LeicsPlanets Professor John Bridges, School of Physics and Astronomy
