Desert springs are remote pools of water, an unexpected and unlikely sight in a landscape defined by dryness. For millennia, they sustained life across the western United States, guiding migration and shaping where people settled. They are living archives, holding both human and natural history in the same small patch of ground, rare lifelines that sustain biodiversity, cultural history and hydrological systems far out of proportion to their size. Their depletion is often gradual, easy to miss without some memory of what these places once were. … “Hidden Waters” acts as a witness to what remains, a memory to hold on to. Some springs will not return to what they were. But the act of making their decline visible refuses to let them slip quietly into absence.
