Geology of the Ozarks, part 6

Bruce Stinchcomb

Lower Pennsylvanian rocks and fossils of the Boston Mountains, the southern
and highest part of the Ozarks. Much of this rock is sandstone, rock made from
sediments carried by ancient streams to what at the time (300 million years ago),
was the edge of the North American continent (Laurentia). Some of the views
shown here as well as the Lower Pennsylvanian plant fossils shown occur along
the Ozark Highland Trail, Hurricane Creek portion. The Ozark Highland Trail is
a continuation of the Ozark Trail of southern Missouri. Middle Pennsylvanian rocks
occur in the Missouri Ozarks and were often preserved from erosion by being
deposited in ancient sinkholes.
