Photograph of an aerial view of Stinking Creek. The back of the photograph proclaims, “Aerial view of Stinking Creek. The alluvial soils are Port clay loam and the principal uplands are Tillman-Hollister soils. Much of the land is in irrigated cotton."

Photograph of Jake Ringwald and Hubert Mobley, SCS Soil Scientists, peering into recently formed gyp sink hole, which is approximately 30 feet deep and 15 feet wide. The photograph does not identify the left to right positions of Ringwald or Mobley. The back of the photograph proclaims, "Jake Ringwald and Hubert Mobley, SCS Soil Scientists, peering into recently gormed [sic] gyp sink in a gentley [sic] sloping what field of Tillman clay loam soil. The hole is approximately 30 feet deep and 15 feet wide. See Ok-720-12 for inside of hole."

Photograph of the Red River. A large area of riverwash. Many thousands of acres of this land makes up thesandy channel of the Red River. The land has very little agricultural value but provides a habitat for wildlife. OK-743-6.

Photograph of combining alfalfa on Tipton loam, 0 to 1% slopes. Land Class I. This is a choice soil as is well suited to all principal crops grown in this country.

Photograph of range land. Aerial view of rangeland. The area is mostly in the Breaks, Shallow and Red Clay range sites. Mesquite trees and shrubs dot the landscape. OK-143-11.

Photograph of a soil survey. Harmon stony loam. A very shallow to shallow soil developed on dolomitic limestone. Class VI land. Shallow Range site. OK-720-6.

Photograph of a soil survey. While making the soil survey, Richard Graft, Soil Conservation Service [SCS] scientist, discovered a recently-formed gyp sink [= a sinkhole] in a gently sloping wheat field of Tillman clay loam soil. The gyp sink is approximately 30 feet deep and 15 feet wide. OK-720-12.

Photograph of range, soil survey near Altus, Oklahoma. Sub-irrigation range site on soil type Spur clay loam, Land Class [unclear]. Very productive site when properly managed. OK-593-2.

Photograph of the Red River. A large area of the riverwash. Many thousands of acres of this land makes up the sandy channel of the Red River. The land has very little agricultural value but provides a habitat for wildlife. OK-748-6.

Photograph of an UNIDENTIFED soil scientist conducting a soil survey by using a hand level to obtain the percent of slope on the land for use on a standard soil survey. The back of the photograph proclaims, “Soil Surveys. Soil Scientist using a hand level to obtain the percent of slope on the land for use on a Standard Soil Survey."

Photograph of jetties set norht of highway bridge to keep river from cutting around west end of bridge. Note damage silt can cause. River has practically no defined channed and almost no banks. West end of highway bridge has been lost several times from this river eating away the west bank of the river.

Photograph of irrigated Arizina combine grain sorghum growing on Reinach soil of very fine, sandy loam 0 to 1% slopes. This crop following alfalfa has had two 3-inch applications of water. Mr. Hughes estimates 4000 pounds of grain per acre.

Photograph of conservation crop rotation. Austrian winter peas. 150 acres seeded in November 1956 for soil improvement. Good nitrogen fixation when photo was taken. An excellent growth, field has been in wheat for several years and with a wheat crop to planted in 1957. Seeding rate is about 20 pounds per acre. Seed inoculated. No fertilizer applied. Ray Murell, Work Unit Conservationists [WUC] in the picture. OK-456-1.

Photograph of Mr. J.W. Rhoades operates the hydraulic controls and lifts the nose of the "Little Skojer" ditcher. Mr. Rhoades designed and built this original ditcher with parts from old farm equipment, an old electric refrigerator and washing machine and surplus war materials.

Photograph of sand deposits in Cult. Land subject to overflow of Lebos (sandy) Creek, tributary of Red River. Cow peas are planted in the straight rows. Yohole V. F. S. L.

Photograph of a scene on Birdie Coker's farm.

Photograph of Class I land untreated, closely drilled to oats. Large closely stacked shocks of grain indicate profitable yield. Due to long slope, the field will be terraced for water conservation. Less than 1% slope. Olustee, silty, clay loam. OK-8180.

Photograph of "Chunk" Reid spot-seeding and pitting native grasses.

Photograph of "Chunk" Reid spot-seeding and pitting native grasses. Note the excellent job of grass management.

Photograph of Guar and field peas drilled on acreage reserve for a cover crop to be plowed under for soil improvement. This field was planted to rye and turned under in 1957.

Photograph of stream bank cutting. Temporary stream bank erosion control measure. Bridge is located in a bend in the river and each time the water rises some more bank is eaten away near the end of the bridge. These trees are held in place by a cable and keep the water away from the raw bnk of the river. The section of bank from the man in photograph to the present location of bank was eroded away in one year.

Photograph of trial grass plantings. Chiseled area, 12 inches deep, in native grass pasture which was reseeded to native grasses: blue grama, buffalo and side oats grama. The native pasture grasses were 80% dead as the result of drought conditions. The field trial was made to determine the effects of seedbed preparations. The broom weed in the chiseled area was killed while the native grasses left showed signs of recovery. This planting was made in cooperation with the Soil Conservation Service [SCS]. OK-360-3.

Photograph of stream bank at end of highway bridge at west end eroded away in spite of temporary erosion control measure of cottonwood trees cabled to bank. The west approach of the bridge was also washed out. Repair of the approach of bridge was $30,000 for 600 foot section whcih had to be replaced. Permanent control structure is being installed to reduce this type of damage in the future at a cost of $100,000.

Photograph of permant type control measure being installed to reduce stream bank erosion by holding this stream in its original banks so it will flow through the present bridge. In July, 1955 a temporary stream bank erosion control measure of cotton wood trees cabled to the bank was installed but the west approach of the bridge received serious damage in 1956. The cost to repair bridge approach was $30,000 and the permanent channel control structure will cost $100,000. Some permanent upstream flood control structure would reduece this flooding.
