Billy Barr, a young graduate began measuring snow in a Colorado ghost town to keep himself occupied; 50 years later, his notebooks were helping scientists understand a changing climate

Billy Barr began recording snow and weather data in Gothic, Colorado, over fifty years ago. His handwritten notebooks later became a valuable scientific resource for researchers. Barr's long-term observations reveal significant changes in snow patterns and seasonal cycles. Scientists now use his ground-level data alongside modern aerial and satellite measurements.
