The Dwarf Pine, or White-Bark Pine (Pinus albicaulis), forms the extreme edge of the timberline throughout nearly the whole extent of the Range on both flanks.

矮松或白皮松（Pinus albicaulis）构成了林线的最边缘，几乎遍及山脉两侧的整个范围。

Though apparently it is perfectly bald, there are four clumps of pines growing on the summit, representing three species, Pinus albicaulis, P. contorta and P. ponderosa, var. Jeffreyi — all three, of course, repressed and storm-beaten.

虽然它显然是完全光秃秃的，但山顶上生长着四丛松树，代表三个物种，Pinus albicaulis、P. contorta 和 P. ponderosa, var. Jeffreyi——当然，这三个人都受到了压抑和风暴的打击。
