Historic great floods of the Green River: This figure shows the flood stage of the Green River in December 1867 (blue area) compared to today (orange lines). Transect shows levee locations. In the 1800s, this was the White River (which now connects to the Puyallup). From doi.org/10.1371/jour...

A quick search on Google Maps shows Pituffik Space Base is at 76°32'N, 68°50'W. Not 76.32N, 68.50W. I hope the Space Force does better work on their antiballistic missile trajectory calculations. Photo from the NY Times.

To address the precedent in a longer term context, the paleo record, in Scott Mensing's cool study of large charcoal particles accumulating in the Santa Barbara basin, shows that large Santa Ana fires have been occurring for at least 560 yrs. doi.org/10.1006/qres...

Floods and fluvial geomorphology, lake sediment and landslides, alluvial fans and age-depth models, varves and tree-rings, pollen and paleoseismology, and, of course, forest fire, and how they all fit together to tell a story of Holocene river dynamics in the Puget Lowlands. doi.org/10.1029/2024...

My amateur cartography. With lower sea level. But isostatic effects were substantial too.
