Every named stream in the Adirondack Park — the feeder waters that line the High Peaks valleys and fill the ponds.
Lillian Brook is a named tributary in the Keene network — one of dozens of small feeder streams that trace through the northeast High Peaks corridor before emptying into the East Branch of the Ausable. No formal access or developed trail follows the brook, and no fish species data on record suggests it's either too small or too intermittent to support a fishery. The name shows up on USGS quads and older forestry maps, which means it likely mattered to loggers or guides a century ago — but today it's off-grid water, the kind you cross on a bushwhack or notice from a ridgeline. Worth knowing the name exists if you're plotting routes through the Keene backcountry on paper.
Little Black Brook flows through the Keene township corridor — one of dozens of modest tributaries feeding the larger Ausable watershed, unmapped by most trail guides and undocumented in the fishing reports. Brooks like this one thread through private land, state forest, and roadside culverts with little fanfare: they're the connective tissue of the drainage, not the destination. Without access data or a clear put-in, it remains in that large category of Adirondack moving water that exists on the DEC inventory but lives mostly in the memory of surveyors and the boots of hunters who know where the old woods roads cross. If you're poking around Keene and catch a bridge sign for Little Black Brook, you've found it — but there's no trailhead waiting on the other side.
