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.
Avalanche beacons work by detecting the electric field given off by other beacons. They use the strength and direction of this field to determine the location of the second beacon. They are used by anyone entering an area where avalanches may occur - essentially in the mountains, outside the managed area of a ski resort. Each person wears a beacon strapped to their body (so it doesn't get ripped off during an avalanche).
