This map visualization displays hiking routes across Colorado from the summer of 2019, with each trail rendered as an orange polyline over a dark Mapbox basemap. It uses the Mapbox GL JS library to load GeoJSON data from a remote server and display the trail geometries as line layers. Hovering over a route triggers a popup that shows the hike’s name, date, and description, while the cursor changes to indicate interactivity. The map centers on the state’s central mountain region, allowing users to explore the spatial distribution of the recorded hikes.
