On this dive I blazed past Titanic depth at 12,000 ft and was only a third of the way down, and the numbers keep going up and up and up on the depth gauge. You just kind of look at them with a sense of disbelief, and you wonder if the bottom is ever going to be there..
Ocala Chert. Ocala Chert (also known as Coastal Plain Chert), is a beige to cream-colored rock that occurs as float across much of southeastern Alabama (e.g., Houston and Henry Counties). It was the lithic material of choice for people living in southeast Alabama for the manufacture of chipped-stone tools such as spear points and knives.
Portions of the Ozark Plateau, the Springfield plateau of southwest Missouri and northern Arkansas, are underlain by Mississippian cherty limestones locally referred to as Boone chert consisting of limestone and chert layers. These are eroded and form steep hills, valleys and bluffs.or example, the ecoregion called Ozark Mountain Forests includes the Ouachita Mountains, although the Arkansas River Valley and the Ouachitas, both south of the Boston Mountains, are not usually considered part of the Ozarks.
