They fish in it and they live off the tourists drawn to their turquoise waters, but now the Cook Islands wants to dig deeper, up to 6,000m (19,685 ft), where the nodules lie.
The specimen was preserved in pyrite, or fool's gold, making it easy to produce 3D models of the fossil using CT scans. Credits: Luke Parry/Yu Liu/Ruixin Ran (3D models). - courtesy Luke Parry/Yu ...
This list of Michigan rivers includes all streams designated rivers although some may be smaller than those streams designated creeks, runs, brooks, swales, cuts, bayous, outlets, inlets, drains and ditches. These terms are all in use in Michigan.
