Mojave National Preserve issued an incident update on July 30. The state archive gives August 1 in its start field. The earlier contemporaneous bulletin is enough to show that fire activity predated the state entry.

Why the York Fire cannot have started on August 1
This is a source conflict with a practical fix: use the park chronology to establish that the fire was already under way in July, and label August 1 as the state listing date. The incident location spans California and Nevada; a single California county row cannot allocate the full footprint by state.
