Someone has decided this stretch of river needs a number. A man leans over a tripod-mounted levelling instrument at the water's edge, sighting towards a painted mark on the cliff face reading "PR" and "N," the kind of benchmark that turns a wild gorge into a line item in a government ledger. A second figure stands half in shadow behind him, holding a staff or plumb line, doing the unglamorous work that never appears in the finished report.
The cliff itself has been dissolving and redepositing itself in slow motion for longer than any survey crew's career, its striped tufa face a record kept without anyone's permission. The two men are measuring a water level that will be different by autumn, on the confident 1960s assumption that a number written down in a field book counts as permanent. It is the particular vanity of hydrology: nature moves the goalposts, and the surveyor writes down where they were standing when he looked away.
Someone in a government office, decades later, will pull this exact benchmark and be mildly surprised the river has ideas of its own.
