Every named stream in the Adirondack Park — the feeder waters that line the High Peaks valleys and fill the ponds.
Lost Brook drains north through the Raquette Lake Wild Forest — one of dozens of small tributary streams feeding the Raquette watershed in a region better known for its sprawling lake access than bushwhacking headwater runs. The name suggests early surveyor or logger lineage, but no formal trail or DEC lean-to appears on current maps, and the stream sees almost no documented angling pressure. If you're poking around the backcountry between Raquette and Forked Lake, Lost Brook is the kind of drainage you cross on a bearing or find on an old quad — not the kind you plan a trip around. Worth a look if you're already in the neighborhood with a topo and time to spare.
