Trinity County, California

Released on July 23, 2012
Forest fires and logging are the two main drivers of change in this area within Trinity National Forest in northern California. Roger Eckart and his siblings bought a grandfathered-in piece of private land within the forest in 1972, and so together the Eckart family and the Landsat program have observed changes in the forest for over 40 years.
