  • A team from the Narrative and Emerging Media program at Arizona State University, led by the program's founding director, utilized Cronkite journalism news passes to document the fire-damaged areas 1m3s.

Fieldwork Challenges and Scanning Techniques

  • Fire crews encountered in the area were supportive of the documentation team, offering assistance such as water and food 1m25s.
  • The documentation process was physically demanding and hazardous, requiring the team to wear hazmat suits, heavy boots, and double-filtered masks to navigate toxic air and debris 1m43s.
  • Specialized equipment designed by photojournalist Mike Caronna, featuring 3D-printed parts mounted on poles, allowed the team to capture 360-degree imagery that was later fused together using artificial intelligence 1m55s.
  • The scanning process involved using phone cameras like paintbrushes to capture every angle of the environment while avoiding hazards like broken glass and upturned nails 2m15s.
  • Graduate student Ashley Buschhorn and colleague Mary Mathieson participated in the documentation, often working in dangerous conditions to secure high-quality scans 2m32s.
  • The team scanned a variety of objects and structures, including melted trash cans, vehicles, and personal items, often working until daylight faded 2m48s.

Documenting Personal Losses and Property Damage

  • The documentation included the homes of friends and acquaintances, some of whom had not yet returned to see the status of their properties 3m15s.
  • Several personal losses were documented, including the home of a cello teacher, a location used for a baby shower, and the equipment of a horseback riding instructor who lost her home while attempting to rescue horses 3m28s.

  • Despite the destruction, some items survived the fire, including a college photograph and a love letter from a husband written 27 years prior 1m45s.

Insurance Documentation and Resilience

  • 3D scans of the fire damage were used to prove the existence of items, such as a sofa, to an insurance company when receipts had been destroyed 2m12s.
  • A program card signed by Mark Hamill in 2009 survived the intense heat of the lithium-battery fire 2m32s.
  • The experience of loss is described as a time for reflection and remembering, rather than just emptiness 3m15s.
