The central Afghan highlands are in the center of Afghanistan, mostly located between 2,000 and 3,000 m above sea level. They have a very cold winter, and a short and cool summer. These highlands have mountain pastures during summer (sardsīr), watered by many small streams and rivers. There are also pastures available during winter in the neighboring warm lowlands (garmsīr), which makes the region ideal for seasonal transhumance. The highlands in Australia are often above the elevation of 500 m. These areas often receive snowfall in winter. Most of the highlands lead up to large alpine or sub-alpine mountainous regions such as the Australian Alps, Snowy Mountains, Great Dividing Range, Northern Tablelands and Blue Mountains. The most mountainous region of Tasmania is the Central Highlands area, which covers most of the central-western parts of the state. Many of these areas are highly elevated alpine regions. The Ozarks cover nearly , making it the most extensive highland region between the Appalachians and Rockies. This region contains some of the oldest rocks in North America.
