Photograph of a follow-up picture of Okla-5969 of the progression of a Masonry arch drop in stabilizing gully erosion. The back of the photograph proclaims, “Masonry Arch Drop, Gully Control Terrace Outlet Channel. Masonry structure was built latter part of 1937 in natural wash, badly gullied, to accelerate silting for erosion stabilization. Outlet channel on right is now well vegetated, providing safe waterway and former active erosion hehand [sic] structure is almost 100% stabilized.” Both men in this picture are UNIDENTIFED.

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 a retired field with severe washing causing a small gully to form. A dirt road is on the left of the photo and several buildings are in the background. The back of the photograph proclaims, "Gully control with small earthen dams. Small gullied area retired from cultivation because of severe washing. Small dams have Bermuda roots mixed in to promote vegetative cover. Vernon F. S. L."

Photograph of erosion control project. Lateral roads were formerly unassessable due to huge gully across roadbed. Area has been resectioned and sloped, a drop inlet and two culverts constructed by WPA. Safer roadways and safer waterways result.

Photograph of roadside erosion control project. Fill has been made in road and drop inlet and old bridge and severe gully formerly filled the center area of this intersection. Lateral roadways were impassable before erosion control work was started.

Photograph of masonary arch drop, gully control terrace outlet channel. Masonry structure was built latter part of 1937 in natural wash, badly gullied to accelerate silting for erosion stabilization. Outlet channel on right is now well vegetated, providing safe watersay and former active erosion behind structure is almost 100%.

Photograph of "Class II land. Level ridge-type terraces constructed on gently sloping heavy textured soils to conserve moisture and soil." A barn or house is in the distant background.

Photograph of strips of native grass consisting of Blue grama and little bluestem on contour. A house sits in both the immediate and distant background of this photograph. The back of this photograph proclaims, “Strips of Native Grass on Contour Blue gramma [sic] and Little bluestem. Area on left retired from cultivation and grass becoming established. Cultivation continues between strips to provide income from land while grass becomes established. Strips planted spring of ’37 at rate of 30# to A after preparation of seed bed. Vernon F. S. L. 3 to 4% slope.”

Photograph of a control plot, Red Plains Experiment station. Average annual soil loss from the Bermuda grass plot, bare hard fallow plot and de-surfaced plot. About 10 inches of the surface soilwas removed from the de-surfaced area in 1929 when the experiment was started. This area has been planted to continuous cotton with rows up an down the slope. OK-3348.

Photograph of a pasture on Vernon clay infested with mesquite. Eradication of the mesquite would aid in improving the native stand of buffalo and grama grasses.

Photograph of Vernon clay with wind erosion in the foreground and rough, broken land (Vernon soil material) is in the background, consisting of exposures of “red Buds” shale and are of low value as pasture land. OK-8402
