Precious opal from British Columbia? Impossible! Except that, as I write this, I hold a specimen in my hand which shows bright flashes of red, green and orange fire. This is the first recorded find of precious opal in British Columbia - or anywhere in Canada. It is beautiful.

One of the advantages of being a geologist is that you often get to travel to places and see things being done in ways that are vastly different from back home. One example, that might be of interest to some of our readers, is the oil-mining operations of South Sumatra, Indonesia.

Caldera eruptions such as the one which produced Crater Lake, Oregon, were originally thought to be massive explosions which blew the top off the original volcano. Ferdinand Fouque, a French geologist, showed that the caldera could not have been formed by destruction of an earlier cone, since there was not enough material from the original cone in the deposits formed by the eruption. In his 1879 book on the eruption of Santorini, Greece in 1628 B.C. he concluded that the missing part of the volcano had sunk below sea level.

What were the forests like on southern Vancouver Island, British Columbia at various times during the past 10,000 years? How have fish populations changed in the past in Saanich Inlet, a fjord north of Victoria. How frequent were forest fires in the region and how were they related to climate? How many major earthquakes have there been in the greater Victoria area since the glaciers left? What can past changes in climate and oceanography tell us about what we can expect for the future on southern Vancouver Island?
