mjacobson@tahoedailytribune.com SOUTH LAKE TAHOE, Calif. — Bigger fires from multiple lightning strikes in the Mokelumne Wilderness were a higher priority and led to the decision to not immediately attack and extinguish the Tamarack Fire that began on July 4, officials said on Tuesday. Officials said the Tamarack Fire was one of 23 reported on land in the Humboldt-Toiyabe Forest and when it first started, it was a single tree burning on a rocky ridge with sparse fuels and natural barriers to contain it. The forest service said it monitored the blaze everyday after it began and was still only at .25 acres six days later on July 10, according to service updates. But six days later the blaze exploded due to “extreme” winds and low humidity and raced down a slope and spread fast overnight, the service told the Tribune.
