長白山天池(chi)(Changbai mountain pool in the sky)是(shi)一座休(xiu)眠(mian)火山,火山口積水成湖,夏融池(chi)水比(bi)天還要藍;冬(dong)凍冰(bing)面雪一樣的白,被16座山峰環(huan)繞,僅在天豁峰和龍門峰間有一狹(xia)道(dao)池(chi)水溢出(chu),飛瀉(xie)成長白瀑布,是(shi)松花江(jiang)的正源。
長白(bai)(bai)山(shan)(shan)形成于1200萬年前地(di)質造山(shan)(shan)運動(dong),經過(guo)多(duo)次噴(pen)發(fa)而拓成了(le)巨型的(de)傘面(mian)體,當(dang)火山(shan)(shan)休眠(mian)時涌泉溢出,形成十余平方千(qian)(qian)米(mi)的(de)浩瀚(han)水(shui)(shui)(shui)面(mian)。天池海(hai)拔2189.1米(mi),略呈橢圓型,南北長4.4千(qian)(qian)米(mi),東西寬3.37千(qian)(qian)米(mi)。集水(shui)(shui)(shui)面(mian)積21.km2,水(shui)(shui)(shui)面(mian)面(mian)積9.8km2,水(shui)(shui)(shui)面(mian)周長13.1千(qian)(qian)米(mi),平均水(shui)(shui)(shui)深(shen)204米(mi),最深(shen)處達373米(mi)。總蓄水(shui)(shui)(shui)量20.4億立方米(mi)。天池水(shui)(shui)(shui)溫(wen)為(wei)0.7℃-11℃,年平均氣(qi)溫(wen)7.3℃。天池像一(yi)塊(kuai)瑰麗的(de)碧玉(yu)鑲嵌在雄偉的(de)長白(bai)(bai)山(shan)(shan)群峰(feng)之中(zhong),是(shi)中(zhong)國最大的(de)火山(shan)(shan)湖(hu),也是(shi)世界上最深(shen)的(de)高(gao)山(shan)(shan)湖(hu)泊。現為(wei)中(zhong)國、朝(chao)鮮兩(liang)國的(de)界湖(hu)。
