Map showing the temporal and spatial distribution of 267 fire-scarred red pine (Pinus resinosa Ait.) trees sampled across a landscape in north-central Pennsylvania, USA. White dashed lines indicate approximate locations of documented Native American paths (Wallace 1965), white italicized sample numbers and black-dashed arrows indicate locations for the four oldest trees in the study, and one tree of special interest (BHA006) which recorded nine fires between 1535 and 1564, a period for which very few fire scars have been recovered in the eastern USA
