Small patch within larger marl fen between railroad and Evitts Run; part of large marl wetland complex under TNC easment at Altona/Peidmont marsh. Wetland is surrounded by agricultural fields.;Tall (7') colonial graminoid patch of hard stemmed bulrush fen with thick marsh fern "understory". Hydrology controlled by Evitts Run to south and RR bed (subparallel to Evitts Run) to north. Underlain by low permeability marl and ancient buried peat(and probably has minimal impact on hydrology.) Uppermost peat layer indicates continuity of ecological processes over milennia.
