Philippe Deslandes, in his third year building the Snowcastle that appears on Yellowknife Bay each March, talks us through what changes when it's a February as bleakly cold as this one.

Also on the show: Brett Hansen and Mallory Chipman tell Jasmine Nasogaluak about their NACC show Confluence, and former journalist Amanda Lindhout – held captive in Somalia for more than a year – talks to Emily Blake about the lessons she's bringing to Yellowknife from that ordeal.
