Watching the events in Oregon today, Barrs presser (Kansas), and several drops including the word 'Castle Rock'. I did a little diggin. Found some interesting items that may warrant peer review.
Castle Rock:
Castle Rock was a landmark on the Butterfield Overland Despatch route (Overland Trail). The chalk was deposited in the area by an ancient inland sea. The formation was formed by the weathering of the chalk by wind and water. It received its name because it is said to look like a castle rising above the prairie.
Weathering of the rock formation is increasing due to visitors climbing on the rocks. In 2001, following a thunderstorm, the tallest spire fell.
On January 29, 2008, Castle Rock and Monument Rocks 31 miles to the west were jointly named as one of the 8 Wonders of Kansas.

Overland Trail:
The Overland Trail (also known as the Overland Stage Line) was a stagecoach and wagon trail in the American West during the 19th century. While portions of the route had been used by explorers and trappers since the 1820s, the Overland Trail was most heavily used in the 1860s as a route alternative to the Oregon, California, and Mormon trails through central Wyoming. The Overland Trail was famously used by the Overland Stage Company owned by Ben Holladay to run mail and passengers to Salt Lake City, Utah, via stagecoaches in the early 1860s. Starting from Atchison, Kansas, the trail descended into Colorado before looping back up to southern Wyoming and rejoining the Oregon Trail at Fort Bridger. The stage line operated until 1869 when the completion of the First Transcontinental Railroad eliminated the need for mail service via Thais' stagecoach.

Oregon Trail: (second paragraph)
The Oregon Trail was laid by fur traders and trappers from about 1811 to 1840, and was only passable on foot or by horseback. By 1836, when the first migrant wagon train was organized in Independence, Missouri, a wagon trail had been cleared to Fort Hall, Idaho. Wagon trails were cleared increasingly farther west, and eventually reached all the way to the Willamette Valley in Oregon, at which point what came to be called the Oregon Trail was complete, even as almost annual improvements were made in the form of bridges, cutoffs, ferries, and roads, which made the trip faster and safer. From various starting points in Iowa, Missouri, or Nebraska Territory, the routes converged along the lower Platte River Valley near Fort Kearny, Nebraska Territory, and led to rich farmlands west of the Rocky Mountains.
