Permanent No. 344394. Temporary No. 2700. Photo Sta. No. 126. Looking west from point near the SE corner of the Burroweed plot near Foothill Sta. Showing a few scattered mature burroweed plants and no burroweed reproduction in a .2 stand of Rg, Bf, Ad, and G. The soil is porous and there is no erosion. Burroweed is slow to invade into this type of range. Mesquites are scattered and very little Mes reproduction shows on the area. This view is typical of the gently sloping mesas near this area and is at the upper limit of the burroweed at the present time. This area will be cleared. Photo by Cribbs, S.R.E.R. 3/4/37. 400-B.
