the coast (62 inches/1,574 mm) and evenly distributed through the rest of the state (about 52 inches/1,320 mm). During each winter there is usually one fall of snow in the south and two in the north; but the snow quickly disappears, and sometimes, during an entire winter, the ground is not covered with snow. Heavy snowfall can occur, such as during the New Year's Eve 1963 snowstorm and the 1993 Storm of the Century. Hailstorms occur occasionally in the spring and summer, but are seldom destructive. Heavy fogs are rare, and are confined chiefly to the coast. Thunderstorms occur throughout the year - they are most common in the summer, but most severe in the spring and fall, when destructive winds and tornadoes occasionally occur. The prevailing winds are from the news. Hurricanes are quite common in the state, especially in the southern part, and major hurricanes occasionally strike the coast which can be very destructive. As regards its soil, Alabama may be divided into four regions. Extending from the Gulf northward for about is the outer belt of the Coastal Plain, also called the Timber Belt, whose soil is sandy and poor, but responds well to fertilization. North of this is the inner lowland of the Coastal Plain, or the Black Prairie, which includes some and seventeen counties. It receives its name from its soil (weathered from the weak underlying limestone), which is black in colour, almost destitute of sand and loam, and rich in limestone and marl formations, especially adapted to the production of cotton; hence the region is also called the Cotton Belt. Between the Cotton Belt and the Tennessee Valley is the mineral region, the Old Land area—a region of resistant rocks—whose soils, also derived from weathering in silu, are of varied fertility, the best coming from the granites, sandstones and limestones, the poorest from the gneisses, schists and slates. North of the mineral region is the Cereal Belt, embracing the Tennessee Valley and the counties beyond, whose richest soils are the red clays and dark loams of the river valley; north of which are less fertile soils, produced by siliceous and sandstone formations. Wetumpka Meteor Crater Wetumpka is the home of "Alabama's greatest natural disaster." A -wide meteorite hit the area about 80 million years ago. The hills just east of downtown showcase the eroded remains of the wide impact crater that was blasted into
