Corral Hollow has a long history of cultural, industrial, and recreational
activity. Prior to settlers arriving from the East, Corral Hollow was populated
by Native Americans and an abundance of wildlife, including grizzly bears,
coyotes, deer, feral pigs, wild turkeys, bobcats, and badgers.
In the 1800s, the area was mined for coal. William H. Brewer, who explored
Corral Hollow in the 1860s, wrote about the area and describes its rugged features
and tortuous terrain:
If you look on the map, southeast of Mount Diablo, you will find a valley,
'Corral Hollow,' watered by a curved river, enclosed in the mountains. If you
are posted in newspapers you have heard of the 'rich coal mines' in said Corral
Hollow. Well, here we are! As distance lends enchantment to the view, just
believe it a lovely spot; but as we are here, we find it a most Godforsaken,
cheerless, inhospitable, comfortless region.
Corral Hollow runs up west into the mountains, then suddenly turns southeast,
the canyon much narrowing at the same time. The coal mines are near the curve,
about nine miles up. The sandstone that forms the hills is broken and thrown up,
and there a few seams of poor coal are found.
We took a circuitous route up, which we thought we could shorten several miles
on the return by descending into the Corral Hollow canyon above its curve and
following it down. We descended into it, a narrow gorge more than a thousand
feet deep, down a very steep slope, our mules sliding and getting down as best
they couldit was too steep to ride thema slope of thirty degrees or
morethen struck down the stream. We got into a fix.
The gorge got narrow, huge rocks had fallen in and choked it up in places, but
we got our mules down nearly to the road, when the route became absolutely
impassable. We spent two hours in getting them about a mile through the rocks,
and then had to get them out by making them climb a slope having a average
incline of forty-seven degrees, and in places over fifty degrees, for five or
six hundred feet. Think of that! But they did it, and we got out safely.
Up and
Down California in 1860-1864: The Journal of William H. Brewer
In the 1960s, over 1,500 acres of Corral Hollow was opened as a privately-owned
motorcycle park. In 1979, the State of California purchased the property and
created the Carnegie
State Vehicular Recreation Area, which spawned several generations of
off-road enthusiasts. In the late 1990s, an additional 3,000 acres of land was
purchased by the state for planned inclusion into Carnegie SVRA. As a result,
tension has increased between recreational users of the park and natural
resource groups concerned with the impact to the park's ever-diminishing
population of hardy creatures.
Beginning in 2001, Team Wrong Way
hosted the first Groovy
Gravity Games (a.k.a 'GGG'). The first GGG had 126 riders, free shuttles to the
top of the ridge, and a post-race raffle with over $10,000 worth of bike gear
and a Mountain Cycle Tremor FR-1 frame. The GGG was held in 2002, 2003, 2004 and culminated
in 2005 with the
notorious mud fest.
In 2006, Team Wrong Way passed the torch to RideSFO. In recognition of the
area's rich history, the GGG was renamed the Corral Hollow Downhill. More
commonly known as CHDH, the race continued the tradition as set by Team Wrong
Wayflowy turns, high-speed runways, gnarly jumps, and the infamous g-out
sectionfollowed by an epic raffle.
In 2007, RideSFO expanded the event to include a three-race series, placed a
speed gun at the bottom of the g-out to clock the fastest rider, crowned
per-category and overall series champions, and with permission of the park,
teamed with a local Bobcat operator to build up the course to feature gnarlier
jumps linked by large, sweeping berms, a mini g-out, and, across the finish
line, a crowd-pleaser double.
As NorCal's closest off-road vehicle park, Corral Hollow is also a region of
historical, natural, and cultural significance.
Just over the hills southeast of Livermore, an arid valley called Corral Hollow
runs east to the San Joaquin plain. In the early days of the Gold Rush, Corral
Hollow was a part of a major thoroughfare from the San Francisco region to the
southern Sierra. It has been the site of Native American occupation, explorers'
camps, travelers' way stations, mining enterprises, a brick factory, a railroad,
and a town-all gone now, leaving only subtle traces on the landscape. It is the
home of a remarkable variety of plants and animals, bringing many desert-adapted
species surprisingly close to East Bay cities. It has long provided
opportunities for research and training in field biology. But it has also been
the focus of land-use disputes in recent decades, pitting ranchers, residents,
and biologists against off-road vehicle recreationists. Today that struggle is
heating up again, and the fate of a precious natural resource for the Bay Area
hangs in the balance."
