How scoring works

Every day gets a star score from 1.0 to 5.0. The model blends surface conditions (pack quality or drainage timing), weather (temperature, wind, sky), and forecast confidence. Each trail is tuned differently: Camp Murphy is a sand-pack model, Markham is a drainage advisory, and Quiet Waters weights comfort weather more because its surface stays rideable.
