Salt marshes and shallow, ephemeral lakes can form in and near salt flats, dust sinks, and sandy wastes. Most are only a mile or two across, but a few – such as the Salt Meres or the Maze of Draj – extend for as much as hundreds of miles. The water, too salty or alkaline to sustain life, is undrinkable. Many salt marshes dry out completely in the months of High Sun, and some remain dry year-round if the following Lowsun comes and goes without rain.
A salt marsh contains low grasses, reeds, or b rush. Ankle-deep channels of briny water encrusted with caked salt wind through the marsh, sometimes opening out into large, shallow lakes. Here and there, tough stands of scrub or the occasional tree stand above the grasses. Few creatures can digest the tough vegetation, but the marshes buzz with tiny insects that can drive a traveler half mad.
