6. These are two large incense-cedars. The
finger-like sprays of foliage, tapered trunk, and
pencil fragrant wood are features of the incensecedar. It never grows in pure stands but is mixed
with other conifers of the yellow pine belt. The
heavy, shreddy bark resembling that of the redwood covers its durable fragrant wood. Cedar is
valuable where resistance to moisture is important, such as posts and shingles, and, of course,
the common lead pencil. The cedar grows well in
either moist or dry conditions, but its slow growth
prevents it from dominating the forest environment.
7. The shrub all around this marker is California hazelnut. The
spreading loose stems and finely-haired, bluntly-pointed leaves are
characteristic of California hazelnut. In early spring it produces
the male catkins hanging worm-like and then the solitary, small,
pink female flowers appearing before the leaves. Animals eat the
nuts even before they ripen.
8. As you stand here and watch the quiet babbling of Rock
Creek, imagine the water that is flowing as a great living organism,
with its heart in the mountains that supply its life blood. This
blood flows out through the streams that form the arteries above
and below ground, coming down from a hundred thousand hidden sources, the mountain springs and meadows, the patches of
moist woodland with the porous soil beneath them, the shaded
snow banks and the afternoon thunderstorms, the flow of every
raindrop held back by grass and flowers, absorbed by bits of rotting wood, filtering into the soil through a million root tunnels
and worm holes, delayed, but slowly moving down the hillside
through the soil, to bring a steady, even flow of life to the valleys
below.
9. The California yew is extremely durable and
will try to adapt to change in its environment
such as flooding and drought, or even damage to
its own branches. Here a yew has been sliced right
down the middle of its crown as if by a large
meat cleaver. The tree is still healthy and will
probably continue to grow with two crowns.
