The ridges or strings are arranged at right angles to the slope, which is usually less than 2?. They are typically 1 to 3 m wide, up to 1 m high and may be over 1 km long. Although the ridges are usually parallel to one another, they may interconnect at acute angles. On nearly level fens the ridges are farther apart but shorter; and they interconnect frequently, giving a roughly polygonal appearance. Since the strings are elevated, they are better drained and allow shrubs and trees to grow on them. String fens are composed of sedge-fen peat with some woody shrub remains. The ridges are composed of moss-sedge or moss peat. They are best developed in the zone of discontinuous permafrost and immediately to the south of the permafrost region. In the central and northern parts of the zone of discontinuous permafrost, the ridges are often perennially frozen. Permafrost conditions may extend into the underlying soil.
