- Most spring floods are triggered by rain or melting snow, but when the Skafta River of southern Iceland flooded in late April 2006, geologic activity may have been the driver. The river flows out from under the Vatnajokull Ice Cap, a large permanent field of snow and ice that covers more than 8,000 square kilometers of southeastern Iceland, including a number of volcanoes and other regions of geothermal activity. Over these hotspots, the lower layer of the ice cap melts to form glacier lakes, some of which drain into the Atlantic Ocean through rivers such as the Skafta. Other lakes are dammed by walls of ice from the overlying glacier. Catastrophic floods can occur when water breaks through the ice dams and bursts into the rivers, or when geologic activity increases and melts more water.
- Franklin Pierce (Wikipedia)
Franklin Pierce (November 23, 1804 – October 8, 1869) was the 14th president of the United States, serving from 1853 to 1857. A northern Democrat who believed that the abolitionist movement was a fundamental threat to the nation’s unity, he alienated anti-slavery groups by signing the Kansas–Nebraska Act and enforcing the Fugitive Slave Act. Conflict between North and South continued after Pierce’s presidency, and, after Abraham Lincoln was elected president in 1860, the Southern states seceded, resulting in the American Civil War.
