SOIL HORIZON DESCRIPTION:

Colours of C horizons are dominated by the coarse fragments.  C2 horizon was not sampled.  Colours are for moist soil.

Ah:    0-20 cm; Dark yellowish brown (10YR 3/4) extremely gravely sandy loam, structureless, loose, many very fine to medium roots, calcareous, HCl ++, 80% 0.2-1 cm coarse fragments, clear wavy boundary. NaF +

C1:     20-50 cm; Black (10YR 2/1) sandy gravel, structureless, loose, common very fine to medium roots, slight evidence of stratification, non calcareous, 95% 0.2-2 cm coarse fragments, abrupt wavy boundary. NaF +

C2:     50-70+ cm; Black (10YR 2/1) sandy gravel, structureless, loose, no roots, non calcareous, NaF +.

WRB (2001): ochric horizon (0-20 cm); no Leptosol because of <90% coarse fragments between 0 and 50 cm; no Arenosol because of >35% coarse fragments between 0 and 50 cm; BS >80% throughout:

Skeleti-Tephric Regosol (Hypereutric)

ST (1999): ochric epipedon (0-20 cm); no Psamment because of >35% rock fragments in the particle-size control section (25-100 cm):

Pumiceous, mixed, nonacid, thermic Vitrandic Xerorthent
