About 70 percent of the volume and surface area of spruce-fir logging slash lies below the mid-depth of the slash. Material 0 to 1 centimeter in diameter was distributed vertically in the same proportions as all other material. Old slash in the first 20 centimeters above the ground contained a higher proportion of large material than new slash. Quantity of slash averaged 26.5 kg./m.^2 (118 tons/acre) dry weight with 0.57 kg. /m.^2 composed of material 0 to 1 centimeter in diameter. Bulk density of slash decreased vertically and averaged 0.030 g./cc. for new slash and 0.053 for old slash. Needle mats suspended in the slash occurred with a 40 percent frequency.
