paragraph_text: Stewart Peak, elevation , is a summit in Colorado. The peak is the second highest thirteener (a peak between 13,000 and 13,999 feet in elevation) in the state. It is located in the La Garita Mountains, sub-range of the San Juan Mountains, in Saguache County, within the La Garita Wilderness. Stewart Peak is the 55th highest peak in Colorado by most standard definitions, just missing the list of Colorado fourteeners. At one time, the peak's elevation was measured to be over 14,000 ft and it was believed to be a fourteener, but more recent and accurate surveys have dropped it below that threshold.

paragraph_text: Tibet (i/tᵻˈbɛt/; Wylie: Bod, pronounced [pʰø̀ʔ]; Chinese: 西藏; pinyin: Xīzàng) is a region on the Tibetan Plateau in Asia. It is the traditional homeland of the Tibetan people as well as some other ethnic groups such as Monpa, Qiang and Lhoba peoples and is now also inhabited by considerable numbers of Han Chinese and Hui people. Tibet is the highest region on Earth, with an average elevation of 4,900 metres (16,000 ft). The highest elevation in Tibet is Mount Everest, earth's highest mountain rising 8,848 m (29,029 ft) above sea level.

paragraph_text: Which state or territory is ``highest ''and`` lowest'' is determined by the definition of ``high ''and`` low''. For instance, Alaska could be regarded as the highest state because Denali, at 20,310 feet (6,190.5 m), is the highest point in the United States. However, Colorado, with the highest mean elevation of any state as well as the highest low point, could also be considered a candidate for ``highest state ''. Determining which state is`` lowest'' is equally problematic. California contains the Badwater Basin in Death Valley, at 279 feet (85 m) below sea level, the lowest point in the United States; while Florida has the lowest high point, and Delaware has the lowest mean elevation. Florida is also the flattest state, with the smallest difference between its highest and lowest points.

paragraph_text: Tsai writes that shortly after the visit by Deshin Shekpa, the Yongle Emperor ordered the construction of a road and of trading posts in the upper reaches of the Yangzi and Mekong Rivers in order to facilitate trade with Tibet in tea, horses, and salt. The trade route passed through Sichuan and crossed Shangri-La County in Yunnan. Wang and Nyima assert that this "tribute-related trade" of the Ming exchanging Chinese tea for Tibetan horses—while granting Tibetan envoys and Tibetan merchants explicit permission to trade with Han Chinese merchants—"furthered the rule of the Ming dynasty court over Tibet". Rossabi and Sperling note that this trade in Tibetan horses for Chinese tea existed long before the Ming. Peter C. Perdue says that Wang Anshi (1021–1086), realizing that China could not produce enough militarily capable steeds, had also aimed to obtain horses from Inner Asia in exchange for Chinese tea. The Chinese needed horses not only for cavalry but also as draft animals for the army's supply wagons. The Tibetans required Chinese tea not only as a common beverage but also as a religious ceremonial supplement. The Ming government imposed a monopoly on tea production and attempted to regulate this trade with state-supervised markets, but these collapsed in 1449 due to military failures and internal ecological and commercial pressures on the tea-producing regions.

paragraph_text: The government broadened land ownership by returning land that had been sold to large landowners in the late Ming period by families unable to pay the land tax. To give people more incentives to participate in the market, they reduced the tax burden in comparison with the late Ming, and replaced the corvée system with a head tax used to hire laborers. The administration of the Grand Canal was made more efficient, and transport opened to private merchants. A system of monitoring grain prices eliminated severe shortages, and enabled the price of rice to rise slowly and smoothly through the 18th century. Wary of the power of wealthy merchants, Qing rulers limited their trading licenses and usually refused them permission to open new mines, except in poor areas. These restrictions on domestic resource exploration, as well as on foreign trade, are held by some scholars as a cause of the Great Divergence, by which the Western world overtook China economically.

paragraph_text: While the Ming dynasty traded horses with Tibet, it upheld a policy of outlawing border markets in the north, which Laird sees as an effort to punish the Mongols for their raids and to "drive them from the frontiers of China." However, after Altan Khan (1507–1582)—leader of the Tümed Mongols who overthrew the Oirat Mongol confederation's hegemony over the steppes—made peace with the Ming dynasty in 1571, he persuaded the Ming to reopen their border markets in 1573. This provided the Chinese with a new supply of horses that the Mongols had in excess; it was also a relief to the Ming, since they were unable to stop the Mongols from periodic raiding. Laird says that despite the fact that later Mongols believed Altan forced the Ming to view him as an equal, Chinese historians argue that he was simply a loyal Chinese citizen. By 1578, Altan Khan formed a formidable Mongol-Tibetan alliance with the Gelug that the Ming viewed from afar without intervention.
