some quotes from an artilce about bc's ground fires

"You need a combination of very deep ground fuel — that means duff and litter and roots and buried logs — and then you need drought conditions," Gray told CBC.

"If you have that combination, then you have fires that can get into that deep, deep, dried organic material, and with just a little bit of oxygen they can hang on for years."
