There are two summits atop the mountain: Signal Hill, which reaches {{convert|2,753|ft}}, and Mossback Ridge, which reaches {{cvt|2,700|ft|m|1}}. EtymologyMount Magazine gets its name from French explorers who, while traveling through the area, witnessed a landslide on the mountain. The noise from the landslide was so great that one explorer described it as the sound of an ammunition magazine exploding, hence the name "Magazine". The U.S. Geological Survey's Geographic Names Information System (GNIS) indicates that the official name of this landform is "Magazine Mountain", not "Mount Magazine". Generally "Mount [Name]" is used for peaks and "[Name] Mountain" is used for ridges, which better describes this landform. Mount Magazine appears in the GNIS as a ridge with Signal Hill as its summit.[4][5] "Mount Magazine" is the name used by the Arkansas Department of Parks and Tourism, which follows what the locals have used since the area was first settled. Mount Magazine is often called "the highest point between the Alleghenies and the Rockies", but there are many parts of Texas, Oklahoma, Kansas, Nebraska, South Dakota, and North Dakota with higher elevations.[6] LocationMount Magazine is located due north of Blue Mountain Lake in Logan County, Arkansas, approximately {{convert|45|mi|km|abbr=on}} east of the Arkansas-Oklahoma border. The most scenic route to the top is a {{convert|10|mi|km|abbr=on}} drive along Highway 309 (also known as the Mount Magazine Scenic Byway) from Havana. Many consider Mount Magazine to be part of the Ouachita Mountains, though it is really part of the Arkansas River Valley.[7] It lies within a southern extension of the Ozark National Forest despite being much closer to the Ouachita National Forest.

This unit has the largest areal extent of any of the Paleozoic formations in Arkansas, extending as far north as the Boston Mountains, and is divided into upper, middle, and lower members.[12][7] See also{{portal|Geography|Arkansas|Mountains}}
