Where..............dry high plains collide
with the Niobrara....
...............Great Northern tablelands crumble
into jumbled sandhills....
...............Ponderosa pines fade
in shadows of Burr oak and Birch....
...............Minnechaduza, Niobrara, and Snake
merge, headed East ... fast -

Then.................You must be at the place
