The Red Dirt of Kauai
The soil of Kauai has a strikingly orange-red colour. Aside from the lush green foliage and colourful flower blossoms, the red dirt is what catches the eye. Why is the dirt so red? Kauai soil is an oxisol in nature. Oxisols are iron-oxide rich soils normally found in the tropics. Since the Island of Kauai is the oldest island amongst the Hawaiian Islands, the high iron content of the volcanic soils has had plenty of time to oxidize in the humid conditions of Kauai Island (rains every day, albeit for just a short while).
