Northern New Mexico Fire Graphs
How to read these fire graphs:
  • Each long horizontal line represents one tree
  • Each short vertical mark represents a crossdated fire scar
  • The composite chronology at bottom shows vertical lines for years with at least two trees recording a fire scar
  • The "Prior to 1900" number is average time interval between composite fires
