Here’s the recent research.

Fascinating stuff. The Willamette is incredibly fertile. Where I live, the indigenous Pueblo people along the Rio Grande have been farming and living in settled communities for centuries. (See Chaco Canyon, Taos Pueblo and Acoma Pueblo.) They were flanked on one side by the Navajo Apache and on the other by the Comanche. Those aren’t exactly fertile regions, and until the Spanish reintroduced the horse, those peoples were nomadic scavengers scraping a hardscrabble existence on foot. The Pueblo tribes considered them barely human, and the Navajo to this day call the Pueblo people “Pebbles” as a derogatory term.

Edit: And by accident of geography, the Pueblo tribes along the Rio Grande now have huge casinos stringing from Santa Fe to Isleta south of Albuquerque, while the Navajo don’t have running water or electricity to most of their reservations in NM/AZ. Hence the resentment.

They had an advantage in having a huge lake to draw on: before they started each burn, everything along the edges for fifty feet got drenched.
Farther south on the trail there were two spaces where the trail had actually been relocated, spots where the prescribed burns got a bit out of hand and spread. Once the trail actually went through a burned area because there was no way to go around it – kind of eerie, and a bit strange because every now and then we passed a tree with a burned-out top but lower branches that were still green. In evolutionary terms, it will be the seeds from those few rare trees that will provide the ongoing generations of trees and at least one species in the forest will be a little more fire resistant.
