With 70 degree days predicted for early next week, we will be seeing more and more of our returning songbirds and waterfowl. Sandhill Cranes, robins, red-winged black-birds, starlings, bluebirds and such are already singing, in addition to Cardinals, titmice and other year-round residents. Sandhills are still very quiet, so they don’t seem to be claiming their nesting territories yet. Send us your comments!! Click here to see our birding archive on the Ramblin’ On blog.
With so little snow this winter, spring flooding is unlikely this season. To see an interactive flood map, as well as past flooding accounts, click here.
[adsenseyu2]We had a beautiful barred owl in our backyard early one morning last week. Hawks are paired up and bald eagles are nesting. I’ll be watching for the return of white pelicans next… they follow the opening of the Mississippi River… perhaps looking for fish kill as the ice breaks up.
We have featured WHITE PELICANS, EAGLES and other large waterfowl for many years on www.greatriver.com
Please visit our dedicated Birding Index here at Greatriver.com It includes a long history of arrival dates for the sandhill cranes in the Upper Mississippi River valley.
Could an Earthquake Happen in the Midwestern United States?
With all the media coverage of the 7.0 magnitude quake in Haiti
in January 2010, interest has shifted to the USA.
We all think of California immediately, but could it happen
here in the MIDWEST? Think NEW MADRID FAULT,
right under the Mississippi River!
Scientists suggest there is a 25% chance of a 7.5 magnitude quake by the year 2040. A quake of this magnitude would be felt throughout half of the United States and cause damage in twenty states or more.

Intensity map for the New Madrid Fault
The New Madrid Fault is a major active fault line that runs approximately from Memphis, Tennessee, to St. Louis, Missouri. On Dec. 16, 1811, this area was hit with an estimated 8.6 magnitude quake on the modern-day Richter scale. This was the first of THREE major quakes to rock the Midwest. A second quake on January 23, 1812 is estimated to have been an 8.4. A THIRD shock on February 7, 1812, is estimated to have been the strongest jolt ever to hit the North American continent at somewhere near 8.7 to 8.9.
We pulled some illuminating facts from Volume 3 of DISCOVER! America’s Great River Road…What would an 8.7 magnitude earthquake feel like?
The New Madrid earthquake released energy equal to 150,000,000 tons of TNT. In comparison, the two atomic bombs dropped on Hiroshima and Nagasaki in WWII equaled 35,000 to 40,000 tons of TNT!!
When the tremors and convulsions of the earth subsided, 30 to 50 thousand square miles of land had undergone vast topographical changes. Most of which are visible today. In the northwest corner of Tennessee, land dropped 10 to 20 feet and caused the Mississippi River to flow back upon itself which formed REELFOOT LAKE. In places along the Mississippi River, I have seen sandboils which still lie barren, or waves of undulating earth frozen into the compacted soil.
The New Madrid fault system extends 120 miles southward from Cairo, Illinois, through New Madrid andCaruthersville, Missouri, following I-55 free way system to Bytheville and on down to Marked Tree, Arkansas. Buried five to to ten miles underground (similar in depth to the Haiti quake), it crosses five state lines and cuts across the Mississippi River in three places.
THE USGS maintains a real time list of tremors along the New Madrid fault. Click map image to see the map for today.
Stories from SURVIVORS of the New Madrid Earthquake of
related in part from “Reelfoot Lake and the New Madrid Fault” by Juanita Clifton, 1980
Witnesses report that about 2 a.m. on December 16, 18aa, the earth around the little settlement of New Madrid, Missouri, began to rise and fall like waves upon the sea. When the peaks of the waves rolled through the Mississippi River, the river bottom heaved up, emptying the river onto its banks, inundating the shores and leaving some boats on dry land. When the troughs followed, the river rushed back into the hollows with such force that entire groves of trees were drawn out by the roots and thrown into the river.
On dry land, trees bent like heads of grain in the wind, their ranches interlocked, until they were ripped from the ground. Cracks formed in the earth that sometimes ran for MILES. The quake’s ground wave created sunken lands, fissures, and domes. Sand blows eruped sand and belched hot water, fumes, and carbonized wood.
Mattis M. Speed, a river traveler in February, 1812, described his experience. “We were awakened about 3 a.m. by the violent agitation of the boat accompanied by a noise so terrible it can best be described as the constant discharge of heavy cannon. The banks were falling into the river and the island to which we were tied was sinking. We cut ourselves loose from the island and pulled as far from the banks as necessary to avoid the falling trees. The swells of the river were so deep as to threaten the sinking of the boat with every minute.”
When he pulled out of the maelstrom at New Madrid, he wrote, “The former elevation of the bank was about 25 feet above common water. When we reached it, it was barely 12 or 3 feet. Scarcely a house was left entire, some completely prostrated, others unroofed and not a chimney standing.”
One man described holding to a tree to support himself during a quake. A fissure opened in the ground and both he and the tree fell in. He was unable to climb out of the fissure at that point and was forced to walk along it until an incline allowed him to scramble out. Fissures as deep as 100 feet ran for miles through the countryside.
New Madrid Earthquake Creates Reelfoot Lake
Both Reelfoot Lake, Tennessee, and St. Francis Lake in Arkansas were formed by the New Madrid Earthquake in 1811, 1812. A citizen from New Madrid, Missouri, wrote in 1816, “Lately, it has been discovered that a Lake was formed on the opposite side of the Mississippi River, in the Indian country, upwards of 100 miles and from one to six miles wide, of a depth of from 10 to 50 feet.”
The epicenter of the quake was about 70 miles southwest of modern Reelfoot Lake and more than 1800 recorded tremors, some of which rang bells on the east coast, followed by the first powerful jolts.
In 1815, Congress passed an act to relieve area inhabitants who found their riverside farms swallowed up or buried in the sand that spewed from the earth. More than 500 earthquake “certificates”, redeemable for up to 640 acres of government land, were allotted. The site of Hannibal, Missouri, was one of the resultant land grants.
The TIPTONVILLE DOME
A dome-like rise in the otherwise perfectly flat land is clearly visible on the west side of Reelfoot Lake, on the road from the Airpark Inn to Tiptonville, Tennessee. The Tiptonville Dome formed when the land around Reelfoot Lake sank during the earthquake. Above the newly formed depression, the Mississippi River appeared to flow backward when the waters rushed to fill the depression–the center of which is now Reelfoot Lake.
The raising of the dome also created a natural dam that, for a short time, forced the Mississippi River to flow back south upon itself. The same dam trapped water in low swampland in the vicinity of Reelfoot Creek and Bayou de Chien, eventually allowing Reelfoot Lake to form.
RAILROAD STORIES..True Adventures, Humorous Tales, and High Melodrama from the Days of Steam [Kindle Edition]
What a difference two weeks can make! River is frozen. Swans long gone. Ice Fishermen abound. Eagles will be searching out open areas in the ice field. And while you may see local fishermen out on the ice… BEWARE. River ice cannot be trusted, even from day to day. River currents EAT ice.
A fisherman friend relayed that he used a special truck for ice fishing… the top had been removed so that if he fell through the ice, he could immediately push off and head for the hole.
Well, it happened that he DID fall through, and he immediately swam to the surface break. Current is obviously a great enemy, but hypothermia strikes in minutes.
He found himself sitting on the edge of the fragile ice edge, kicking his feet in the water. He had to logically think, “this is not normal. I SHOULD be freezing to death.”
So he pulled his body up and ran for the highway where he had his “road truck” parked. He made it to the truck, started out onto Hwy 35. He did reach the highway… and stopped right in the path of traffic.
Another driver stopped behind him, realized something must be wrong, and found Harold hypothermic behind the wheel of his truck.
130,000 acres of agricultural land floods after a deliberate break in the Birds Point Levee south of Cairo.
The FLOOD OF 2011 is threatening to rival the flood of 1927!
I can’t think of a more dangerous place to be in the world just now than at the confluence of the Ohio and Mississippi Rivers! Levees completely encircle the city of Cairo, forming an island during floods and the Mississippi River begins to back up into the Ohio River.
For an INTERACTIVE MAP of where flooding is at its worse, visit www.greatriver.com/FLOOD.htm
Some 60% of the water that flows through the U.S. passes through this confluence, including much of the deep south, via the north-flowing Tennessee and Cumberland Rivers. As this is the 150th anniversary of the Civil War, it is worth noting that General Grant named Cairo Fort Defiance when it was occupied by the Union Army.
