The ten small scenes show a one mile square area in the Olympic National Forest to the northwest of the Olympic National Park on the Olympic Pennisula in northwestern Washington State. Clear cutting in the area was already well underway at the time for the first Landsat scene in 1984. Public land use policy changes in the late 1980s resulted in timber cutting relocating from public lands to private holdings. Some revegetation of the clear cut areas can be seen in the later data.
A set of four full Landsat scenes showing the entire Olympic Pennisula, including this area of the Olympic National Forest, is also available (see animation 899).
North is up in all these images. The Landsat scenes use Thematic Mapper data from bands 5, 4, and 2 displayed as red, green, and blue respectively. In this color scheme, dense conifer coverage appears dark green, bare soil or cultivated land appears reddish, while the light blue on the peaks of mountains and ridges is snow.
