Predominantly Mexico, but some species are found ranging as far south as northern South America. "D. australis" occurs at least as far south as southwestern Guatemala, while "D. coccinea" and "D. imperialis" also occur in parts of Central America and northern South America. "Dahlia" is a genus of the uplands and mountains, being found at elevations between 1,500 and 3,700 meters, in what has been described as a "pine-oak woodland" vegetative zone. Most species have limited ranges scattered throughout many mountain ranges in Mexico

Apart from this there is a wide range of latitudes on which glaciers develop from 5000 m in the Altiplano mountains and volcanoes to reaching sealevel as tidewater glaciers from San Rafael Lagoon (45° S) and southwards.

This list of the tallest buildings in South America ranks skyscrapers in order by height. South America has historically seen a relatively modest demand for skyscrapers. Most of the continent's high-rises are in Argentina, Brazil, Chile, Colombia, Uruguay, and Venezuela, and the tallest buildings are located in Santiago, São Paulo, Buenos Aires, Caracas, Montevideo, Rio de Janeiro, Valencia and Bogotá, all of which are the biggest financial centers of these countries.

Atkinson embarked on a world record attempt to be the youngest person to climb the tallest mountain on each of the seven continents when he was 11 years old. He completed it nearly six years later just a few days before his 17th birthday. He climbed the Mount Kilimanjaro, tallest mountain in Africa first. This was followed by Europe's Mount Elbrus at age 13. Shortly before his 14th birthday Atkinson reached the summit of Australasia's Puncak Jaya and returned safely from the summit despite the arrest of his guides and ultimately his own arrest. Peak four was Aconcagua in South America. At age 16 Atkinson climbed Mount Denali in North America, reaching the summit on 12 July 2010, followed by Mount Vinson the highest mountain in Antarctica. The final peak was the world's highest mountain Mount Everest in Asia. Atkinson completed the record attempt when he reached the summit on 26 May 2011, becoming both the youngest person to complete the Seven Summits.

Frémont and two others in 1842. Pico de Orizaba (), the tallest peak in Mexico and third tallest in North America, was first climbed by U.S. military personnel which included William F. Raynolds and a half dozen other climbers in 1848. Heavily glaciated and more technical climbs in North American were not achieved until the late 19th and early 20th centuries.
The first skyscrapers of at least height in South America were built in the 1920s, and included the Martinelli Building in São Paulo,
Palacio Barolo in Buenos Aires, and the Palacio Salvo in Montevideo. Martinelli was not only the first, but the tallest skyscraper of South America until be surpassed by the Altino Arantes Building, also in São Paulo, in 1947.
The southern Appalachian Mountains have the most locations and the tallest trees in the present range of "Pinus strobus". One survivor is a specimen known as the "Boogerman Pine" in the Cataloochee Valley of Great Smoky Mountains National Park. At tall, it is the tallest accurately measured tree in North America east of the Rocky Mountains. It has been climbed and measured by tape drop by the Native Tree Society. Before Hurricane Opal broke its top in October 1995, Boogerman Pine was tall, as determined by Will Blozan and Robert Leverett using ground-based measurements.
