The Living Landscape: Beautiful Big Valley

"Treat the earth well. It was not given to you by your parents- it was loaned to you by your children." – Indian proverb
LAKE COUNTY, Calif. – According to the “History of Lake County – 1881,” a description of the Big Valley's location is, "Beginning at the foot of Uncle Sam this valley extends in a circular course to the south-west, embracing Kelseyville and Highland Springs; thence northerly to Lakeport."
Uncle Sam is the name the settlers gave to Mount Konocti.
The Big Valley was once home to ancient oaks. Settlers cleared the valley for orchards. Acres of prolifically producing pears and grapevines adorn the rich soils now.
The valley was the homeland for peoples of ancient times called the Xa-Ben-Na-Po Pomo Indians.
Here, and elsewhere in what is now Lake County evidence points to the rich lifeways of the people of the past.
The Pomo Indians thrived in Lake County because of the abundance of foods such as acorns – a staple, seeds, game, fowl and, of course a plentitude of fish from Clear Lake and the surrounding streams.
Here is where they garnered a wealth of resources for home-building and constructing boats from the lush tule reeds that once ringed the Clear Lake in profusion.
Obsidian for tool-making was also in abundance due to the volcanic nature of the lands, especially around Mount Konocti and Borax Lake.
When Mexican and Spanish occupation of these lands occurred in the 1800s, the land and lifeways of the Pomo peoples of the past were altered forever.
The Indians were stripped of their sacred hunting and fishing grounds. Soon, settlers appeared and life changed evermore for the Indians when they were forced to work on ranchos and missions.
The Xa-Ben-Na-Po of today belong to the Big Valley Rancheria Band of Pomo Indians. They are working on maintaining their tribe's history and do so via ceremonial and educational events. One of the events is their Tule Boat Festival which is held each year on the lake.
Regarding the Big Valley's geology, according to geologist Dean Enderlin, "Much of the valley is underlain by sedimentary rocks that formed in ancient Clear Lake during the period that Mount Konocti was an active volcano (around 200,000 years ago). These early lake beds were buried and lithified over the millennia, but as the Clear Lake Basin continues to change its shape, some of these deposits have been uplifted, and are now elevated well above lake level. In the Lakeport and Kelseyville area, these ancient lake beds are called the Kelseyville Formation. Further south, by Lower Lake, similar deposits are known as the Lower Lake Formation."
The book entitled "History of Lake County – 1881” discussed Big Valley's geologic features as volcanic in nature with basalt and obsidian, along with limestone.
The obsidian features extend from Mount Konocti, southwest to Cobb Mountain. Much of the obsidian is sharp as a knife and shiny black, and is known as bottle rock, while other obsidian features are spotted, pocked and have the appearance of anthracite. The limestone outcroppings were never considered to be of a quantity to mine back then.
The Big Valley contributes to the value of Lake County's flourishing agricultural crops today, with its pears, walnuts and grapes.
Lake County, overall, has a pear crop that grossed $26,098,171. 00 according to Lake County Department of Agriculture's 2015 Crop Report. In that same year walnuts grossed $5,383,560.00 and winegrapes grossed $63,390,181.00.
The pioneers of The Big Valley paved the way for Lake County's now-abundant agricultural endeavors, when they settled in the Big Valley to grow grapes, sugar beets, vegetables, rye, oats, barley and fruits such as apples.
The abundance of rich soil was and remains conducive to growing lush grasses to allow for cattle to graze upon.
