Here it is scattered among other trees, or forms small groves,
seldom ascending higher than 5500 feet, and never making what would be
called a forest. It is not particular in its choice of soil: wet or dry,
smooth or rocky, it makes out to live well on them all. Two of the
largest specimens, as we have seen, are in Yosemite; one of these, more
than eight feet in diameter, is growing on a moraine; the other, nearly
as large, on angular blocks of granite. No other tree in the Sierra
seems so much at home on earthquake taluses and many of these huge
boulder-slopes are almost exclusively occupied by it.
The Incense Cedar
Incense Cedar (Libocedrus decurrens), already noticed among the Yosemite
trees, is quite generally distributed throughout the pine belt without
exclusively occupying any considerable area, or even making extensive
groves. On the warmer mountain slopes it ascends to about 5000 feet, and
reaches the climate most congenial to it at a height of about 4000 feet,
growing vigorously at this elevation in all kinds of soil and, in
particular, it is capable of enduring more moisture about its roots
than any of its companions excepting only the sequoia.
Casting your eye over the general forest from some ridge-top you
can identify it by the color alone of its spiry summits, a warm
yellow-green.
