Abstract:

This data publication contains radiocarbon ages (RCA) of charcoal fragments obtained from five soil pits excavated to a depth of ≤ 1.5 meters on the leeward flanks of Mauna Loa and Mauna Kea on the Island of Hawaii. Fragments were collected and radiocarbon-dated between 2012 and 2015. RCA of fragments ranged from less than 200 years RCA (2 pieces) to 7,730 years RCA (1 piece), with 13 pieces greater than 1,500 years RCA. We also obtained genus identities for four macroscopic charcoal fragments. Data also include measurements such as charcoal weight, depth below the surface, Δ¹³C, Δ¹⁴C, and Δ¹⁴C age. These findings indicate the existence of fires before humans are known to have occupied the Hawaiian archipelago and contributes to our understanding of prehistoric fires in shaping primary succession in Hawaiian drylands.
