.~ <br />The razorback sucker spawning bar is located 7.5 miles downstream of the Split <br />Mountain Gorge C~nnpground on the south flank of the Split Mountain anticline. Seven miles <br />further downstream is the (Jscalante Vetlands (f i~~ui-c 1). A variety of topographic conditions <br />are found in this broad river valley. !1t the start of the study reach near the spawning bar, the <br />river had pushed a series of meander l?cnds across the old valley bottoms, cutting both <br />vertically and lateralh~, having large eroded hills above the river course. A steep, high cobbled <br />river terrace can be seen along the river to the north near the upstream extent of the reach and <br />to south ~~-here the river opens into a wide valley. Along the south bank at the spawning bar <br />site, the river contacts the steep mancos shale escarpment. <br />Once the river slows out into the valley, a long sweeping meander bend brings it to the <br />north side of the valley. At this location, near the Dinosaur Quarry Road, there is a small <br />vegetated floodplain to the north, slightly sloping to the hogl-lacks associated with the Split <br />Mountain uplift. Abroad, flat cultivated floodplain extends to the south. Further downstream, <br />the river bends sharply to the south against the west valley walls (Photo 1). The wetlands are <br />located downstream of this bend on the east side of the river below the slightly rising bluff line <br />marking the edge of the cultivated floodplain (Figure 1). <br />Photo 1.
