754:. The valley floor is flat and wide, especially at the lower elevations. Due to siltation, virtually no rocks are evident in the streambed. Grazing occurs in the streambed itself, putting pathogens directly into the water. During the rainy season (November to April), this bottomland consists in places of an expansive marshy area. Most native wetland vegetation has been destroyed by ongoing grazing. Grazing is so intense that cattle are seen wading in a broad marshy streambed over 16 in (40 cm) deep and over 300 ft (100 m) wide.
