属于秋天的色彩 Fall colors

Autumnal equinox

This thicket of aspen trees is on the Last Dollar Road, an 18-mile scenic drive in southwest Colorado that is as dramatic as its name suggests, with switchbacks and stunning views of peaks and meadows and of course the aspen trees that paint the land come September. Aspens thrive in the cold winters and cool summers of Colorado, where they grow at altitudes between 5,000 to 11,000 feet, typically reaching heights of 50 feet. Their distinct, round leaves quake in the wind making it appear as if the trees are glittering in the sunlight. Aspens generally grow on west-facing slopes, gorging on the afternoon sun. They're among the world's largest living organisms because aspen groves share a single root system. They're also the state's only native deciduous tree and cover about a fifth of its forested land.

秋分

这片白杨树灌木丛位于科罗拉多州西南部的Last Dollar Road，这是一条18英里长的风景线，正如它的名字所暗示的那样引人注目，在这里可以看到山峰和草地的转弯和令人叹为观止的美景，当然，到了9月份，白杨树也将为这片土地锦上添花。白杨在科罗拉多州的寒冷冬季和凉爽夏季生长旺盛，在那里它们生长在5000至11000英尺的高度，通常达到50英尺的高度。它们独特的圆形叶子在风中摇曳，使树木在阳光下显得闪闪发光。白杨通常生长在向西的斜坡上，饱食午后的阳光。它们是世界上最大的生物之一，因为白杨树林共享一个单一的根系。它们也是该州唯一的本土落叶树，约占该州林地的五分之一。
