gravel coarse material rounded and transported by the main <br />channel. Material is well worked and sorted, and <br />often imbricated. Most often occurs downstream <br />from active debris fans. <br />Submerged gravel cobble and gravel sized deposits submerged but <br />visible during mapping. <br />vegetated gravel vegetated gravel bar. Vegetation is generally willow <br />or young tamarisk and is sparse compared with <br />vegetated fine grained alluvial deposits. <br />Bars formed in recirculating _flow <br />separation bar Sand deposited in recirculating flow. Separation <br />bars occur as a veneer of sand on the lee side of <br />debris fans where downstream current separates <br />from the bank. <br />vegetated separation bar Densely vegetated and stabilized separation bar <br />reattachment bar Sand deposited in recirculating flow. Reattachment <br />bars are paired with, and occur downstream of <br />separation bars. They form where downstream flow <br />reattaches with the bank. <br />vegetated reattachment bar Densely vegetated and stabilized reattachment bar. <br />eddy bar Undifferentiated sand bar deposited in recirculating <br />flow. <br />vegetated eddy bar Densely vegetated and stabilized eddy bar. <br />CO LUVIUM <br />inactive debris fan Material transported from a tributary during flood <br />events. Debris fan material is unsorted and size <br />ranges from silts and sands to boulders. Clasts are <br />angular and often matrix supported. Inactive debris <br />fans are vegetated with desert shrubs. Exposed rock <br />often is blackened with desert varnish and shows <br />signs of weathering such as pitting. <br />submerged inactive debris fans Inactive debris fan that is regularly inundated by the <br />active channel. <br />II
