Type_of_Site:
flowing in sunny area into a large mud flat

Channel_Bed:
white precipitates on rocks; orange algae at source


Channel_Bed:
rocky, bouldery, algae-covered, very slight FeOx staining


Channel_Bed:
very slippery alluvium because of healthy growth of algae


Type_of_Site:
issues from spring in rock-lined pool in sunny area

Channel_Bed:
pools made with alluvial bench gravels; white precipitates on alluvium; pool used by floaters; poison ivy and biting tiny red water mites make this a poor wading pool!

alluvial cobbles and boulders, algae-covered


Channel_Bed:
rocky pink K-spar granite alluvium, mossy; slight FeOx staining


Channel_Bed:
white precipitates on pink granite outcrop; green algae


Channel_Bed:
coarse alluvium with slight FeOx staining


Channel_Bed:
rocky, slippery with algae, slight FeOx staining


Channel_Bed:
coarse granitic alluvium, slight FeOx, rocks slippery because of silt coating--due to recent flush?


Channel_Bed:
granitic alluvium, slight FeOx staining, algae


Channel_Bed:
granitic and felsic porphyry alluvium with slight FeOx staining and algae


Channel_Bed:
very slippery alluvium because of algae covering


Channel_Bed:
algae on pink granitic alluvial boulders; silt coating boulders below surface of water


Type_of_Site:
flowing in open sunny area; steep gradient, turbulent

Channel_Bed:
water flows through large car-size granitic boulders with pockets of finer gravels between; slight algae and moss in places


Channel_Bed:
coarse granite boulders, slight FeOx staining, slight algae

Other_Notes:
creek too large to get composite completely across; water collected below white-water riffle and width integrated across about 1/3 of creek width


Channel_Bed:
silt-covered granitic boulders of gneiss and quartzite


Channel_Bed:
abundant slippery algae covering boulders; slight FeOx staining


Channel_Bed:
steep, bouldery creek with a lot of algae and moss on granitic and gneissic alluvium


Channel_Bed:
coarse granitic and gneissic alluvial cobbles/boulders with abundant sandy sediment between boulders


Channel_Bed:
fine to coarse granitic and gneissic alluvium, slight but pervasive algae in creek


Channel_Bed:
high gradient, swift water; alluvial cobbles covered with algae, no FeOx


Channel_Bed:
gneiss and gneissic granite alluvial cobbles/boulders with a lot of moss and algae


Channel_Bed:
algae and moss covering granite and gneiss alluvium


Channel_Bed:
rocky, deep, and swift; sediment on banks


Channel_Bed:
weak FeOx staining on alluvium; some cobbles contain corroded pyrite; minor algae


Channel_Bed:
coarse to fine alluvium, slightly FeOx-stained, some algae


Channel_Bed:
rocky; silt, algae, and MnOx on alluvium

Other_Notes:
sample collected below riffle, width integrated; only RA collected


Channel_Bed:
silt, algae, and moss covering gravel and boulders


Channel_Bed:
minor FeOx and algae on alluvial gravel/boulders


Channel_Bed:
granitic gravels and boulders; slight FeOx; abundant moss on boulders and banks


Channel_Bed:
gravel to boulders, slight FeOx and algae locally


Channel_Bed:
sandy sediment in pockets between boulders along banks; MnOx on boulders


Channel_Bed:
gravel to boulders, local FeOx and algae on boulders


Channel_Bed:
granite and gneiss alluvium covered with moss and algae; local FeOx on cobbles


Channel_Bed:
rocky, with granitic and gneissic alluvium; covered by algae and moss


Channel_Bed:
granite, quartzite, and augen gneiss boulders; no fine sediment because of high gradient; abundant algae


Channel_Bed:
gneiss boulders along bank with interspersed fine sediment


Channel_Bed:
quartzite, gneiss, and granite alluvium covered with thin algae film and moss


Channel_Bed:
MnOx and silt covering gneiss boulders; algae on shoreline alluvium


Channel_Bed:
coarse boulders of granite and gneiss covered with algae, no precipitates, high energy--sparse fines


Channel_Bed:
granite, gneiss, and quartzite alluvial boulders covered with algae


Channel_Bed:
fine sediment to boulders; granite, gneiss, and schist; slight FeOx and algae


Channel_Bed:
boulders and gravel with very slight FeOx and algae; moss on boulders


Channel_Bed:
gravel and cobbles of quartzite and phyllite; some FeOx staining on cobbles


Channel_Bed:
boulders, gravel, sticks, and root are all stained green from copper
