I never said you didn't, Gordy. Just pointing out some flaws of a poorly written/researched article. Their little graphic with the altitude in meters is amusing too. I'm sure the author was being told altitudes in feet and forgot to convert it. Last time I checked the Palisades weren't anywhere close to 2000m. Anything above 10k feet for more than 30 min the USFS requires oxygen for HLCO operations, I'm sure CalFire would have similar restrictions.
