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.
However, given the right conditions, snow can fracture at any point on the slope. The three parts of an avalanche path are the starting zone, avalanche track, and runout zone.
