This video-poem proceeds chronologically through a winter, following the changes along a little river. The seasonal phenomena are observed and recorded by means of over 50 named varieties of ice, snow, and winter weather in the Newfoundland dialect. It combines poetry, video, still photographs, text, definitions of the local terms, and a two-person voice-over. The word 'treasury' is used for a collection of highly valued poems; I'm using it in the title to describe a collection of highly valued poetic terms. Newfoundlanders developed a wide vocabulary to distinguish specific phenomena in the continuous modulations of winter weather. I hope this video-poem can help keep some of these terms active. They're precise, practical, evocative, sonic, and lyrical, and knowing them helps one actually see the phenomena.
