Summary:: This study examined soil carbon pools and soil development across a high-altitute 20-kyr climate gradient on Mauna Kea in Hawaii. Soils from four elevation sites were analyzed for particle size, organic C and N, soil pH, exchangeable cations, base saturation, NaF pH, phosphorous sorption, and major elements. The results suggest that after 20 kyr, soil development have altered the nature and composition of the volcanic ash and it is capable of retaining soil C even where organic acid inﬂuences from plant material and leaching from rainfall are severely limited.
