Size Matters
The following scale was provided by Hugh Abercrombie of Birch Mountain Resources Ltd, from his presentation to the Hydrogeology Division of the CSPG "Angstroms to Megametres - Hydrothermal Processes across 16 Orders of Magnitude in Northern Alberta", 13th December 2001. It provides an excellent reference for geo-scientists (and other Canadians) to visualise scale (measured in metres).
