UP - soil surface is unstable because of lack of protective 

 vegetation cover 



UA - unable to assess 



EROS TYPE (two-character code) 



Enter one of the following codes to indicate the dominant type 

 of erosion occurring on the plot: 



NO - none 



SE - sheet erosion 



RE - rill erosion 



GE - gully erosion 



DE - deposition 



WE - wind erosion 



SC - soil creep 



SL - slump (earth flow) 



TD - terrace development 



SL - slide 



HORIZON ANGLE (%) (up to three-digit numbers) 

 Record the angles to the four horizons (in percent) . 



IFSLP (up to three-digit number) 



If "General Plot Position" is sloping (i.e., > 3% slope), 

 estimate distance from top of slope to upper edge of plot. 

 Indicate units of measurement. 



IFVAL (up to three-digit number) 



If "General Plot Position" is level (i.e., 0-3% slope), 

 estimate distance across valley or flat (passing through 

 plot) . Indicate units of measurement. 



SPFE 



List any special features of the site on which the plot is 

 located (if desirable, describe these features under "General 

 Site Description"). If none described, enter "NA" . 



Examples: avalanche chute, talus, seep, etc.
