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.
Technically, an avalanche is any amount of snow sliding down a mountainside. It can be compared to a landslide, only with snow instead of earth.he other common avalanche is known as a Full-Depth Avalanche which, as it s name would lead you to believe, occurs when an entire snow cover, from the earth to the surface, slides over the ground. An avalanche can be composed of many different kinds of snow depending on the region, temperature and weather.
