Monument Rocks (Kansas)

Monument Rocks (also Chalk Pyramids) are a series of large chalk formations in Gove County, Kansas, rich in fossils. The formations were the first landmark chosen by the US Department of the Interior as a National Natural Landmark. The chalk formations reach a height of up to 70 ft (21 m) and include formations such as buttes and arches. The carbonate deposits were laid down during the Cretaceous Period in what was then the Western Interior Seaway, which split the continent of North America into two landmasses. They are estimated to have been formed 80 million years ago.

gollark: Pointer arithmetic, for one thing?
gollark: Rust was designed with ownership to start with and still can't satisfactorily chëck everything. C code is typically a horrible minefield of unsafe everything so a borrow checker could have problems.
gollark: > someone, quick! a borrow checker for C<@356107472269869058> Isn't that impossible without stupidly high false positive rates and/or missing many unsound things?
gollark: Maybe I can just expand the theming UI and ship a "monospace and black" theme.
gollark: > But please don't write paragraphs of text in monospaceNo. ALL shall be monospace. Partial monospace would look out of place and kerning actually bad.
