Trinity County, California
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.
