What Happened Here Before
— 300,000,000—
First a sea: soft sands, muds, and marls
— loading, compressing, heating, crumpling,
crushing, recrystallizing, infiltrating,
several times lifted and submerged,
intruding molten granite magma
deep-cooled and speckling,
gold quartz fills the cracks—
— 80,000,000—
sea-bed strata raised and folded,
granite far below.
warm quiet centuries of rains
(make dark red tropic soils)
wear down two miles of surface,
lay bare the veins and tumble heavy gold
in streambeds
slate and schist rock-riffles catch it –
volcanic ash floats down and dams the streams,
piles up the gold and gravel—
— 3,000,000—
flowing north, two rivers joined,
to make a wide long lake.
and then it tilted and rivers fell apart
all running west
to cut the gorges of the Feather,
Bear, and Yuba.
Ponderosa pine, manzanita, black oak, mountain yew,
deer, coyote, bluejay, gray squirrel,
ground squirrel, fox, blacktail hare,
ringtail, bobcat, bear,
all came to live here.
