Description: | A well preserved wind polished pebble. The specimen is composed of an red/brown mudstone. The specimen has a pearly lustre (shine) on its surface, with many weathered smooth faces. This pebble has a flat base and a pentagonal symmetry and five flat faces meeting at a pointed top. The pentagonal shape may indicate the dominant wind directions. These are formed by sand grains blowing in arctic tundra wind storms abrading and polishing the surface of the pebbles. There are many small holes in the base of the specimen. AR/CB 17/05/2010
