Flatirons
The Flatirons are rock formations in the western United States, near Boulder, Colorado, consisting of flatirons. There are five large, numbered Flatirons ranging from north to south (First through Fifth, respectively) along the east slope of Green Mountain (elev. ), and the term "The Flatirons" sometimes refers to these five alone. Numerous additional named Flatirons are on the southern part of Green Mountain, Bear Peak, and among the surrounding foothills. Etymology The Flatirons were known as the "Chautauqua Slabs" c. 1900 and "The Crags" c. 1906. There are two hypotheses regarding the origin of the current name, one based on resemblance to old-fashioned clothes irons, the other based on resemblance to the Flatiron Building completed in 1902. Geology The Flatirons consist of conglomeratic sandstone of the Fountain Formation. Geologists estimate the age of these rocks as 290 to 296 million years; they were lifted and tilted into their present orientation between 80 an ...

Flatiron (geomorphology)
Traditionally in geomorphology, a flatiron is a steeply sloping triangular landform created by the differential erosion of a steeply dipping, erosion-resistant layer of rock overlying softer strata. Flatirons have wide bases that form the base of a steep, triangular facet that narrows upward into a point at its summit. The dissection of a hogback by regularly spaced streams often results in the formation of a series of flatirons along the strike of the rock layer that formed the hogback. Ollier, C.D.

Landmarks In Colorado
A landmark is a recognizable natural or artificial feature used for navigation, a feature that stands out from its near environment and is often visible from long distances. In modern-day use, the term can also be applied to smaller structures or features that have become local or national symbols. Etymology In Old English, the word ''landmearc'' (from ''land'' + ''mearc'' (mark)) was used to describe a boundary marker, an "object set up to mark the boundaries of a kingdom, estate, etc." Starting around 1560, this interpretation of "landmark" was replaced by a more general one. A landmark became a "conspicuous object in a landscape". A ''landmark'' literally meant a geographic feature used by exploration, explorers and others to find their way back to their departure point, or through an area. For example, Table Mountain near Cape Town, South Africa, was used as a landmark to help sailors navigate around the southern tip of Africa during the Age of Exploration. Artificial st ...
