Slide 5-1. Thaptic Hydrudand. Hydrol Humic Latosol. Location: Island of Hawaii, Hawaii. Parent Material: Volcanic Ash. Horizons and Depths: Alternating A and B horizons representing several cycles of soil development and ash fall; A,B 0-250 cm (0-98"); C 250+ (98"+). The prominent layers in the upper 250 cm represent soil horizons. Buried soils at approximately 100 cm and 220 cm are superimposed on various ash falls. The white specks in the C horizon are gibbsite coatings. This soil formed under 3400 to 4000 mm (135-160") of rainfall.
