Moraine Instrument Raising the Blue River

The instrument does not dam the meltwater; it asks the river to hold a vertical memory of its source. Black moraine stones and scraped pylons keep the ceremony answerable to weight, while the eclipsed planet repeats the chamber as a distant measure. Inside the lifted current, a few rocks turn briefly chrome, as if geology could pass through orbit without leaving the ground. The ambiguity matters: waterfall and ascent occupy the same blue body, and engineering becomes less a command than a question posed to gravity.
