Descendants of David Drake have traced their lineage back to the once-enslaved potter and launched an effort to reclaim their ancestor's work. They say the effort has not only reconnected them with their family's legacy but also raised broader questions about art ownership and restitution.

Three days after a catastrophic wall of water, mud and rock tore through Nepal's Himalayan valleys, the scale of the disaster is still coming into focus. At least 579 people are now confirmed dead, nearly 2,000 remain missing, and the danger is not over. Authorities are closely watching lakes formed in the wake of the glacier collapse, amid fears of further flooding. Stephanie Sy reports.

Geoff Bennett discussed more with Dan Shugar of the waterSHED Lab at the University of Calgary.
