Lots of ways to get firewood up there...varies from year to year. It pays to be ready...I got a lot of wood on short notice due to having a sharp saw and a pickup. In 5.5 years I got firewood from the JBER firewood area, from the BLM or whatever office property off Lake Otis (birch bucked to length), some guy on AOD who needed trees cleared out in Wasilly, and neighbor's client's place out by biglake. Heated exclusively with wood and never bought any. Prevailing word was that any wood purchased up there was wet, so drying time needed accounted for. I had no problems cutting in the spring and summer, splitting it small and burning it that year.
