Every named stream in the Adirondack Park — the feeder waters that line the High Peaks valleys and fill the ponds.
Alder Brook threads through the working forest northeast of Tupper Lake — one of dozens of small tributaries feeding the Raquette River system in a region defined more by timber roads and private holdings than by marked trail access. The name marks it on the map, but public put-in points and fishable stretches aren't documented in the usual DEC or trail inventory sources. This is backcountry that exists in the gaps between the paddling routes and the hiking corridors — beaver ponds, overgrown logging grades, and seasonal flow that rewrites itself every spring. If you're looking at Alder Brook, you're likely already holding a surveyor's map or a canoe route someone sketched on a bar napkin.
