Texture sof very gravelly fine sandy loam and very gravelly loam are common . The coars efragments are often flaggy and oriented parallel to the soil surface . Steep slopes an dperiodic snow avalanching are common on this map unit . These soils are usuall yexceedingly to excessively stony .Table 54 .
