Photograph of the Red Plains Experiment Station, Guthrie, OK. Abandoned land which has been out of cultivation for forty years. It was severly eroded and even after forty years only annual grasses and weeds are able to survive. OK-6916.

Photograph of the Red Plains Experiment Station, Guthrie, OK. East farm gully control studies. 4 1/2 miles south of Guthrie, OK. Clumps or pedestals of soil held from ending by bluestream grass. OK-6913.

Photograph of the Red Plains Experiment Station, Guthrie, OK. East farm gully control studies. 4 1/2 miles south of Guthrie, OK.General view of east slope, looking north. OK-R-29.

Photograph of the Red Plains Experiment Station, Guthrie, OK. Blackjack and chinery oak area which was cleared at the same time as that in OK-6909, but was not mowed to keep the scrub [around the?]oak trees from coming back. Compare with OK-6909 and OK-6911. OK-6910.

Photograph of steers on cleared and controlled area of the East farm, Red Plains Experiment Station. Note the area to right in uncontrolled scrubby oak growth. Steers placed on pasture May 1, 1941. OK-8712.

Photograph of little bluestem at the Red Plains Experiment Station. The bluestem was established in the spring of 1940 by 1500 pounds per acre seed-hay mulch. An effort has been made to thresh the seed from material by a small Allis-Chalmers combine. The hay contained considerable moisture, thus the threshed material contained considerable seed. Application was made broadcast on badly eroded sandy loam soil which had previously been cropped to cotton and grain sorghum. After spreading, the material was immediately rolled with a cultipacker. OK-8713.

Photograph of old vegetation at the Red Plains Experiment Station. The old vegetation, after moving mature grass plants, provided a mulch which reduces erosion. This mulch creates a silt deposit and attention is called to the young grss seedlings which are emerging. This is important on badly eroded abandoned areas which are being revegetated. OK-8349.

Photograph of Mr. Frank, cooperator, with a horse drawn cart, spreading manure on a contour field of alfalfa. The back of the photograph proclaims, "Mr. Frank, Cooperator, spreading manure on a contour field of alfalfa. Taken to illustrate an article by Mr. Ivy M. Howard."

Daniel, Project Supervisor, taking a soil sample on Plot No. 9. This is the de-surfaced plot with continuous cotton, on Stevensville Fine Sandy Loam."

Photograph of plots 4, 5, 6, and 7 on the Red Plains Conservation Experiment Station. The back of the photograph proclaims, "Plots 4, 5, 6, and 7 of the Control Plots established in 1929 to record soil and water losses from different kinds of cover and cropping systems, on Stevensville Fine Sandy Loam with 7.7% slope. Plots 5, 6, and 7 are the rotation studies."

Photograph of two UNIDENTIFED men, located in the background, standing next to one of the control plots established in 1929 to record soil and water losses from different kinds of cover and cropping systems. The back of the photograph proclaims, “Control plots established in 1929 to record soil and water losses from different kinds of cover and cropping systems. On Stevensville Fine Sandy Loam with 7.7% slope. (See USDA T-837 for full details on these plots.)"

Photograph of Harley A. Daniel, Project Supervisor, taking a soil sample from a plot on the Red Plains Conservation Experiment Station. The back of the photograph proclaims, "Harley A. Daniel, Project Supervisor, taking a soil sample on Plot No. 5 which is one of the rotation plots. Cotton, wheat and sweet clover, Stevensville Fine Sandy Loam."

Photograph of Harley A. Daniel, Project Supervisor, taking a soil sample from a plot on the Red Plains Conservation Experiment Station. The back of the photograph proclaims, "Harley A. Daniel, Project Supervisor, taking a soil sample on Plot No. 3, which is continuous cotton, on Stevensville Fine Sandy Loam."

Photograph of an aerial shot of floodwater, sediment, and scour damage along Cimarron River. Note the destroyed railroad lines of the left background and part of the bridge on the far right is missing. The back of the photograph proclaims, "Floodwater, sediment, and scour damage along Cimarron River, vicinity of Crescent."

Photograph of flood damage caused by overflow waters of Cottonwood River. Over 5 blocks of Hwy. 33 in Gruthrie, Oklahoma, were covered by water for 12 hours, causing approx. 100 families to leave their homes. Enormous damage was done to crops, soils, highways, bridges and other public and private property. Buildings on the left belong to the Mid-Continent Petroleum Company and tracks of the railroadf spur line are completely covered by water. Note flooded homes and yards in background.
