100' Selma Chalk (limestone) Mounds
As promised the Tenn-Tom is prettier than the Black-Warrior Tombigbee. The terrain is higher, the river wider and the current is weaker. But, it's also shallower.
Inside the Howell Heflin Lock
Speaking of water depths, when cruising between the Chesapeake and the Keys, Nellie's shallow water alarm is usually set for 5'. Since Nellie's aground at 3-1/2', a 5' alarm is the equivalent of a hair trigger. Usually, no sooner does the alarm sound then we're aground. Yes, the alarm's set point could be increased to 6' or 7', but then the alarm would always be soundings. On the Black-Warrior Tombigbee the alarm was set to go off at 15'--three times deeper than on the East Coast! Before we started this trip I never would have imagined that to be the case.
