It was brought to my attention that a piece of the oldest rock in the world is now in Yellowknife. Mark Brown, a northern prospector, has been working for the past year to claim a plot of land along Acasta River where he found the worlds oldest rock. This Acasta River Gneiss dates back 3,962,000,000 years and is one of the most common rocks in the world.

Mark graciously donated some of the rock to the Prince of Wales Northern Heritage Museum for everyone to enjoy and learn from years down the road. To learn more about how he and his team are making out with their adventure, they put together a very well done short documentary on Youtube.
