Summary: Glacier retreat caused by climate change captivates public visitors to National Parks and is consequential for alpine ecosystems, water resources, and global sea level rise. There are over two hundred thousand glaciers on Earth outside of the Greenland and Antarctic Ice Sheets, yet the smallest of these icy features are difficult to distinguish from perennially frozen, stagnant patches of ice. This begs the question, What is a glacier? This talk will present research into the syntax and dynamic thresholds used to identify and categorize small mountain glaciers.
