  46. Hypothesis 1 • Based on Dr Vosloo report • Fire Originated in non V area • Cause – lightning strike on 12 April 2017

  47. Hypothesis 2

  48. Testing Hypothesis 1 • Morris and Vosloo reports one smoulder • Morris photos and location • Sternsdorf pointed different location • Eye witness confirms Morris and Sternsdorf locations • Wind pattern supplied by Vosloo • Vosloo not in Elandskraal on 7 June 2017

  49. Testing Hypothesis 2 • Emails, photos and grids R Morris • Aerial photos • Fire ground investigation • Non V Pattern area • V Pattern Area • Weather Data • Burn scar

  56. Final Hypothesis • Wild land fires first ignite light fuels then spread to heavy fuels • Fire forms a V and grows laterally • Heavy fuels found in clearing • Pine cones out of place • Charred logs out of place • Access paths • Previous human activity • Previous fires • Wind data and fire spread

  57. Finding Origin – V Shape area - First ignition point in clearing Probable Cause - Pine cones and stacked heavy fuels ignited
