Agate Fossil NM

Today we chose to travel south out of the Black Hills versus shooting east across South Dakota. This gave us several hundred miles on Nebraska two lane. There is lots of rolling prairie and rocks in western Nebraska.  Agate, as expected, was a visitor center with several long hot trails.  Eastern colleges and the government have removed most of the visible 90 million year old fossils. One unique feature were fossiled beaver dens which looked like a corkscrew.
