Hi, is "alder fires" a special wood for cooking salmon or is somthing else??? "madera de aliso" is the only thing I have found but I'm not sure about it.

"There, beautiful scenery, exotic native dances, rustic crafts, and unique folklore, topped-off by a delicious salmon dinner traditionally prepared on cedar stakes over ***alder fires,*** will combine to make your visit to Tillicum Village a uniquely Seattle adventure you will long remember!"
