Description :
Sediment cores from Western Lake provide a 7000-yr record of coastal environmental changes and catastrophic hurricane landfalls along the Gulf Coast of the Florida Panhandle. Using hurricane Opal as a modern analog, the AA. infer that overwash sand layers occuring near the center of the lake were caused by catastrophic hurricanes of category 4 or 5 intensity. The millenial-scale variability in catastrophic hurricane landfalls along the Gulf Coast is probably controlled by shifts in the position of the jet stream and the Bermuda High.
