SUBJECT: #15 Archeological Find at Wally's Beach
SYNOPSIS: First discovered during a picnic in 1997, artifacts at Wally's Beach at St. Mary's Reservoir in Southern Alberta date back to 11,300 years. The site is rich in animal tracks, giving a snapshot in time of the prehistoric animal community, including woolly mammoths, camels and horses. The recent discovery of horse blood on a clovis spearhead found at the site along with the skeleton of a horse indicates prehistoric North Americans hunted and butchered now-extinct pony-sized horses. Archaeologists Dr. Brian Kooyman and Dr. Len Hills are part of the research team that believes this provides strong evidence that overhunting, not just climate and environmental changes as previously thought, played a significant role in the extinction of horses in North America around 10,000 years ago.

SUBJECT: #15 Thermal Imaging to Fight Forest Fires
SYNOPSIS: Fighting forest fires is tough with all the smoke and it's a hit and miss exercise dropping water from bombers on the hotspots. Dr. Naser El-Sheimey is working on an innovative system that would meld GPS with thermal imaging technology to develop a real time map that would pinpoint hotspots with a meter or two. This would take the guesswork out of the initial attack for water bombers, saving time, money and resources in forest fire fighting.
ITEM:3TITLE: Dr. Sandy Gow, Professor of History, Concordia University
SUBJECT: #15 History of Oilfield Technology
SYNOPSIS: In the fourth part of this series on changes in oilfield technology, Dr. Sandy Gow looks at the appalling conditions in which early roughnecks lived and worked. There were no hardhats or steel toed boots. Accidents and deaths were a routine part of the job. Then, after World War Two, the provincial government appointed a health and safety commissioner change this situation. Dr. Sandy Gow is writing a book on changes in oilfield technology in the period between 1883 and 1970.
