Why “thalweg” is a great word
The line connecting the lowest points along a riverbed or valley floor, forming the course of deepest flow. From 19th century German Thalweg (modern spelling Talweg), from Thal/Tal ("valley") + Weg ("way, course, path"). Unlike a watershed, which is the high, dividing crest between basins, or a bank, which is the elevated margin framing the channel, the thalweg is the sunken, gravitational heart within the frame itself. It is the current-polished cobble that stays wet when the flood recedes, the hidden seam of sediment where an eddy spins in perpetual return, the precise longitude a dropped stone follows to the sea—the recognition that every valley holds a single thread of deepest gravity, and all water, given time, finds it.
