Charcoal particles and pollen from sediments from a lake in the northern Sierra Nevada were studied to determine the frequency of fires and the dominant vegetation within the adjoining watershed over the last 7,000 years. Fire scars from within the watershed have been sampled to determine the frequency of fires within the watershed over the last several hundred years. A paleomagnetic record of secular variation was constructed and compared to similar chronologies from other studies in the region.
