Article seems out of date by comparison to tallest measurement from mdvadens video post.
But still some fascinating information about redwoods.
Here is where you enter the Redwood Cathedral "When exposed to fire, the bark forms an ablative shield, similiar to the Apollo heatshield. (The Shuttle thermal protection system--fragile, expensive, difficult to apply and maintain, was not ablative.)"
Thats just COOL!! I want some of that armor!!
