ONE TAP TO DETAILS
Every feature opens a full report: 10-day trend charts, hourly
forecasts, historic peaks dating back decades, seasonal comparisons
across multiple years, and side-by-side context from nearby stations.
BUILT FOR EVERY OUTDOOR PURSUIT
Skiers tracking snowpack on their favorite resort. Kayakers checking
flow on a wild and scenic run. Anglers planning a tailwater trip.
Campers reading the upstream forecast. Surfers eyeing a new swell.
Boaters watching reservoir levels. Farmers and water managers reading
seasonal trends.
LAYER TOGGLE PILLS
A single tap shows or hides each POI category — ski, kayak, surfing,
fishing, camping, boat ramps. Built for the way you actually use the
map: one trip type at a time.
