Winter in the sub-arctic region of Yellowknife, Northwest Territories (NWT) is not the average person's idea of a great time. One must really enjoy the cold and the snow in the vast north as the winter is relentless. However for me, a third year geological engineering student, it was a dream come true.
The richest collecting ground for meteorites on Earth is the Antarctic plateau. In most other parts of the world meteorites are camouflaged by other rocks and easily broken down by rain and temperature changes.

The Canadian meteorite recovery rate is modest. Only a dozen have been recovered in the province of Ontario, which is five times as big as the state of Kansas where over 110 known meteorites have been collected. Low population density and inclement weather may conspire with terrain and land-use factors to hinder recovery of falls and finds alike.
Students all across the country are now learning hands-on about the importance of minerals and mineral exploration through an interactive CD-ROM produced as a collaborative effort between the Geological Society of the Canadian Institute of Mining, Metallurgy and Petroleum (CIM) and Science North in Sudbury.

Shooting stars are not, of course, really stars. They are actually small bits of rock and metal that collide with Earth's upper atmosphere and, because of friction, burn up. On rare occasions, man-made satellites and spacecraft parts fall into the atmosphere and burn up the same way.

This satellite view clearly shows the Manicouagan impact site. The ring is developed in impact breccias that were eroded by glaciation and have subsequently been flooded. The circular structure is 70 km in diameter, but the impact site is approximately 100 km wide. Impact shock structures are well developed in the surrounding bedrock of the Canadian Shield. Since this crater is slightly over 200 million years old, the original rim has been removed by erosion. Also on the picture is the Sudbury impact site, as well as Wanapitei crater (not indicated, but close to Sudbury).
