Tangled matter (conglomerates)
A rock draws a path across a beach. A shard of ceramic pipe nestles into the neck of a once-was bottle. Tangled tentacles cascade down an eroded brick that was once clay, that was once sand, was deep underground, hauled out, compacted, mixed, fired, stacked, lived on, lived in, discarded, disregarded, forgotten.
Inert, invisible.
Water buffets round it, ripples rippling, tumbling sediment onto slick glass, tumbling, dulling, smoothing, tumbling. Iron oxide leaches out, seeping, seeping, eddying down river, into the reservoir, into still-shiny pipes, into your glass of water.
