The Four Main Mountain Ranges and Highest Major Summits of Altamasstachia


A map showing the four main mountain ranges and the 53 highest natural points in the U.S. state of Altamasstachia (click to enlarge).

Highest Major Summits of Altamasstachia

This is a list of major mountain peaks in the U.S. State of Altamasstachia.

The summit of a mountain or hill may be measured in three principal ways:
1. The topographic elevation of a summit measure the height of the summit above a geodetic sea level.
2. The topographic prominence of a summit is a measure of how high the summit rises above its surroundings.
3. The topographic isolation (or radius of dominance) of a summit measure how far the summit lies from its nearest point of equal elevation.

Of the highest major summits of Altamasstachia, 53 peaks exceed 3,000 meters (9,843 feet) elevation and 201 peaks exceed 850 meters (2,788 feet) elevation.

Altamasstachia is home to four major isolated mountain ranges: the Gibbs Range, the Jebediah Escarpment, the Mongolia Range and the Three Pinnacles.

Mount Geoffrey in the Gibbs Range is the highest natural point in Altamasstachia.

Of the 53 peaks listed here, 16 are located in the Gibbs Range, 13 are located in the Jebediah Escarpment, 21 are located in the Mongolia Range and 3 are located in the Three Pinnacles.

The Gibbs Range was named for John Casey William Gibbs (1809-1874), an American geologist and explorer who was the first to ascend Mt. Geoffrey, and named the peak after Theodore Franklin Geoffrey (1810-1873), an American explorer and close friend of Gibbs'. The Jebediah Escarpment derives its name from an expedition into Northern Altamasstachia that was led by Richard Lee Jebediah (1802-1866), an American miner and explorer from California who later became an attorney. The Mongolia Range shares the origins of its name with Mongolia County as both were named for Mongolia, the Asian country which early settlers of the area were reminded of, and the Three Pinnacles are so named for their prominence in the otherwise flat terrain of the Orion Fields region they are located in.

NOTE: At the time of this writing (September 9, 2025) this list is under construction until I have the prominence and isolation calculated for all natural points on this list, as well as their namesakes. I wanted to at least get the bulk of this post uploaded on the blog.

Regions of Mallettbarr

Image
  The geographical regions of the U.S. state of Mallettbarr (click to enlarge). There are seven distinct geographical regions in the U.S. state of Mallettbarr. Unlike other states, Mallettbarr's regions do not necessarily have their own culture. [a] [b] Blandsands - Think some parts of the Australian Outback and you'll get a tame version of that here. This region is quite a bland version of that part of the Land Down Under - true to the name "Blandsands." Eastern Prairies - Unassuming fields of prairie grass, farmland and small towns and villages as can be seen in states like the Dakotas, Nebraska, Kansas, Iowa and Missouri. Finanthia - Woodlands, farms and ranches adorn this part of the state. Think Kentucky and much of the Pacific Northwest. Outwater - This is as close to "tropical" as you're ever going to get here in Mallettbarr - Outwater is so named for its location out at sea. Ferry to and from Nantwich Island takes about 45 minutes. Quentins C...

A Basic Guide to Highway Markers in the United States

Image
  The highway markers used by all U.S. states and territories, as well as the Interstate highway and U.S. Route shields (click to enlarge). Many state highway markers are designed with the respective state's geographic shape in mind, or are based off of a particular state symbol (i.e. the highway markers used in Kansas are sunflower-shaped, as the wild sunflower is the state flower of Kansas). Most of the U.S. states use generically rectangular or neutral shape for their state highway markers, and the circular highway shield (which is how state highways are indicated on most maps) are used by the states of Delaware, Iowa, Kentucky, Mississippi and New Jersey and the territory of the U.S. Virgin Islands for signage on their respective highways. Generally, state highways are low-capacity thoroughfares that run across the state or in specific localities, although some state highways are built as expressways or up to Interstate Highway standards if the traffic volume on the route is su...
