The state page pairs a May 2022 start with a June 2023 containment entry and labels the interval 373 days. A separate lessons-learned account places personnel at a Lost Lake briefing on May 27, 2022, on the Arizona side of the response.

Why the Lost Lake archive’s 373 days need caution
The briefing establishes early operational activity, not continuous burning for the full interval shown by the database. Without a contemporaneous final bulletin, the 373 days should remain a description of the state record and should not be used as a verified fire-duration statistic.
