Today on Colorado Edition: We look back on the history of Black cowboys in the American West and how they helped shape what our state would become. And, we travel back to a time before Colorado was a state to hear the story of a man who successfully lobbied to delay statehood until African Americans received the right to vote. We’ll also revisit our conversation with the artist behind the trail maps found at ski resorts across the state. And KUNC’s film critic reviews a movie about the intelligence and emotions of trees.
