Section 785.19(c) Continued. <br />• <br />ing from the haying process. Irrigated fields north of the flood- <br />plain are bordered on the north by dry sagebrush pasture land which <br />appears dark green in color. The boundary is abrupt. The bluff <br />separating the upper fields from the active flood plain has an <br />irrigation ditch traversing it on the upper contour. This water <br />source has maintained green plants (appearing red) along the slope <br />beginning at about the right 1/3 of photograph 359 and extending <br />left to the center of photograph 360. An irrigation ditch also <br />traverses the north edge of the field. It does not appear to have <br />water in it. Most of the fields have been cut for hay. Non- <br />irrigated areas within the fields are distinguished as high ground. <br />• <br />above the level of the irrigation ditch when viewed in stereo, as <br />well as having the color and general appearance of the upland <br />sagebrush-covered land. The remainder of the active floodplain is <br />probably grazed pasture appearing red or green in color. Red areas <br />support green herbaceous plants while the green areas have both <br />herbaceous plants and a cover of silver sagebrush. The red hues <br />indicate that there is sufficient soil moisture to maintain photo- <br />synthesis. This moisture is probably supplied through flood irri- <br />garcon. <br />Bolton Draw is the third subject area. It is located on photograph <br />358 in the lower left quarter and appears as a linear feature, <br />about 1(8 inch wide, beginning just to the east of the existing <br />mine and extending to the northeast to the Canadian River. The <br />scream channel meanders in the floodplain from about an inch from <br />the bottom of the photograph to within a ~ inch of the Canadian <br />River w'nere the floodplain narrows. White colored areas parallel- <br />ing the active floodplain are indications that a large amount of <br />bare ground is exposed. Due to the fact that these areas are only <br />slightly elevated from the floodplain, they are probably saline <br />flats where the drainage is traversing shale deposits.
