Photograph of the Eagle-Pichers Mine, near Commerce, Oklahoma. Here showing the effects of snow fences in checking wind erosion. The coaser silica material has drifted high in the snow fences creating a series of deep drifts of coarser particles. Note the absence of vegetation even though this is located in approximately a 44 inch ppt. [parts per trillion?] zone. OK-2769-5.

Photograph of the area around the Eagle-Pichers Mine, Picher, Oklahoma. Slimes Pond Evaluation of plantings in Commerce, Oklahoma. View facing north-north central portion of planting area (Field no. 2). Cover crop plantings made and to be planted are to determine whether cover can be grown for eventual parennial vegetation plantings. Field borders are prairie hay mulched (3 tons per acre) and anchored with tandem discs. The tallest vegetation row is rye planted on 09-29-1966 and fertilized with 400 pounds per acre of 10-20-10 fertilizer. It was top dressed on 03-26-1967 with 50 pounds of nitrogen per acre. Summer cover crops are to be planted in the north portion of this filed. OK-2768-7.

Photograph of the area around the Eagle-Pichers Mine, Picher, Oklahoma, here showing the drift effects of wind erosion from slime ponds. Drifts of silicas. They blow sand from the abandoned slimes pond, themseleves about 160 acres in size lying immediately to the east of the Central Mill. Plant materials plantings were made along the south side of this area in the fall and spring of 1966 - 1967. OK-2769-4.

Photograph of the Eagle-Pichers Mine area, at Picher, Oklahoma. Vegetation of old dyke around slimes pond being affected by wind erosion producing siliceous dust (sand). The dike constructed to hold water and fines [finer particulate metal] from flotation process. The pond eventually fills with fines and is abandoned. The area devoid of any vegetation is subject to severe wind erosion. This picture depicts fines converting willows and cottonwoods on the dike. The spur rairoad must receive perodic fine removal from the railroad. OK-2769-16.

Photograph of the area around the Eagle-Pichers Mine, Picher, Oklahoma. Slimes Pond Evaluation of plantings in Commerce, Oklahoma. View facing north (Field no. 2). Five rows of rye planted in late September 1966 to determine possibility of growing cover for use in establishing perennial vegetation. The first row from the north was fertilized with 400 pounds of 10-20-10 fertilizer at seeding time (09-29-1966) with 50 pounds of nitrogen top dressed on 03-16-1967. The second row was fertilized at 200 pounds of 10-20-10 fertilizer at planting time with 50 pounds of nitrogen top dressed on 03-16-1967. The third row was fertilized at 400 pounds per acre at planting time on 09-26-1966. The fourth row was fertilized at 200 pounds on 09-26-1966. The fifth row (foreground) was planted in late September 1966 with no fertilizer. OK-2768-8.

Photograph of the area around the Eagle-Pichers Mine, Picher, Oklahoma. Slimes Pond Evaluation of plantings in Commerce, Oklahoma, showing an active slime pond. The fine ground silica is being discharged in a water solution from a ten-inch diameter pipe. These large pools, generally 100 to 160 acres in size, are diked and used for discharging the fine material left after commercial minerals are removed. OK-2767-14.
