Comments

Scotts Bluff is a national monument that was used as a marker for pioneers moving west. The strata of the bluff were deposited horizontally during the Oligocene and consist of sediments deposited under semi arid conditions unrelated to an oceanic environment.  They include siltstone, volcanic ash blown across what is today Nebraska, and sandstones (ancient sand dunes).  There are fossils interspersed among the deposits.

Scotts Bluff National Monument in western Nebraska includes an important 19th century landmark on the Oregon Trail and Mormon Trail. The National Monument contains multiple bluffs (steep hills) located on the south side of the North Platte River; it is named for one prominent bluff called Scotts Bluff, which rises over 830 feet (330 m) above the plains at its highest point. The monument is composed of five rock formations named Crown Rock, Dome Rock, Eagle Rock, Saddle Rock, and Sentinel Rock.
