Every named stream in the Adirondack Park — the feeder waters that line the High Peaks valleys and fill the ponds.
Gill Brook drains the western slopes above Keene Valley — a small tributary system that feeds into the main valley watershed without the fanfare of the named cascades closer to town. It's the kind of water that shows up on a USGS quad but not in trail guides: headwater streams, seasonal flow, visible from roadside pullouts or crossed on woods roads but rarely a destination in itself. Brook trout in the upper reaches when spring runoff settles, though no angler reports worth cataloging. If you're bushwhacking ridge lines between Hurricane and the Dix Range, you'll cross it or something like it a dozen times without learning its name.
Gravestone Brook runs through the Keene Valley corridor — a named tributary in a landscape dense with named tributaries, most of which drain the eastern High Peaks and feed into the East Branch of the Ausable River. The name suggests old settlement or logging-era landmarks, common in a valley that's been continuously inhabited since the mid-1800s, but the brook itself doesn't appear in modern hiking guides or DEC access inventories. No fish data on file, which likely means it's small, seasonal, or both. If you're chasing obscure water names on a map, start with the Keene Valley Library or the town historian — they keep better records than the state.
Guay Creek is a small tributary stream in the town of Keene — minimal public record, no formal trail access or fishery data, and likely seasonal or intermittent flow depending on snowmelt and spring rains. Streams like this one typically drain into larger named waters in the valley system between the High Peaks and the Champlain corridor, but without surveyed access points or angler reports, Guay Creek remains more of a topographic feature than a destination. If you're poking around Keene Valley or Keene proper and cross a culvert or brookside clearing with a hand-painted sign, you may have found it — but don't expect a trailhead or a DEC campsite.
Gulf Brook feeds the East Branch of the Ausable River somewhere in the Keene drainage — a named tributary on the USGS quad but not a fishing or hiking destination in its own right. It likely runs cold and fast off the ridges east of NY-73, carrying snowmelt and summer thunderstorms downhill through second-growth hardwoods before joining the main stem. No established trail follows the brook, no lean-to marks its confluence, no stocking records in the DEC database. If you're bushwhacking the East Branch drainages or pouring over the topo for a remote brook trout search, Gulf Brook is a blue line worth investigating — but expect to be alone.
