They named it Jones County after John Paul Jones, the early American Naval hero who rose from humble Scottish origin to military success during the American Revolution. Ellisville, the county seat, was named for Powhatan Ellis, a member of the Mississippi Legislature who claimed to be a direct descendant of Pocahontas.
An avalanche occurs when the stress (from gravity) trying to pull the snow downhill exceeds the strength (from bonds between snow grains) of the snow cover. Four conditions must be present for an avalanche to occur: 1  a steep slope. 2  a snow cover. 3  a weak layer in the snow cover. 4  a trigger.
Avalanches are rapid movements of large masses of snow down a slope that commonly occur in mountainous regions. Despite what you may have seen in movies and on television, shouting cannot trigger an avalanche, according to the Utah Avalanche Centre.f the avalanche moves fast enough some of the snow may mix with the air forming a powder snow avalanche, which is a type of gravity current. Slides of rocks or debris, behaving in a similar way to snow, are also referred to as avalanches (see rockslide).
