The Wikipedia article of the day for January 7, 2016 is Upper and Lower Table Rock.
Upper and Lower Table Rock are two prominent volcanic plateaus just north of the Rogue River in Jackson County, Oregon, US. Created by a medium-grained lava flow around seven million years ago and shaped by erosion, they now stand about 800 feet (240 m) above the surrounding Rogue Valley. They are jointly owned by The Nature Conservancy and the Bureau of Land Management. The Takelma tribe of Native Americans inhabited the Table Rocks for at least 15,000 years prior to European American settlement. Starting in the mid-19th century during a gold rush, settlers forced the Takelma into reservations. A post office was established nearby in 1872, an airstrip was built atop Lower Table Rock in 1948, and an aviation beacon was constructed on Upper Table Rock in the 1960s. These plateaus, which were not protected until the 1970s, are home to over 70 species of animals and 340 species of plants, including the dwarf woolly meadowfoam. They are popular hiking locations in the Rogue Valley, with over 45,000 visitors annually.
