Jemez Mountains spatial foot print of fire from tree-ring

The large spatial foot print of fire in the Jemez Mountains in the year 1729, as recorded by tree-ring fire scars. The circles are individual trees that were scarred in 1729, with the colors indicating the fire-scar position, or fire seasonality. The predominance of early season scars indicates a spring/early-summer fire.  The grey x's indicate trees that were not scarred. The histogram in the upper right indicates the relative elevation of the fire-scarred trees.
