They shall grow not old, as we that are left grow old: Age shall not weary them, nor the years condemn. At the going down of the sun and in the morning, We will remember them. --Laurence Binyon,"Ode of Remembrance"

I have gathered a posie of other men's flowers, and nothing but the string that binds them is mine own. --Michel Eyquem de Montaigne

Documenting your family history is a lifelong pursuit, a task of pleasure and research that is never completely finished.

Not to know one's ancestors, is to be a tree without roots, a stream without a source. --Kung-fut-se

The wind whispers through the trees, recalling words and dreams and memories of those who left us long ago. --Unknown

St. Basil of Caesarea, born about 330 A.D., said, "A tree is known by its fruit; a man by his deeds. A good deed is never lost; he who sows courtesy reaps friendship, and he who plants kindness gathers love."

Blythe, California
My Home in the Palo Verde Valley

Thomas Blythe (1825-1885), the San Francisco developer and financier, is the namesake of the city of Blythe, California. He first came to the Palo Verde Valley in 1877, and established primary water rights on the Colorado River. The city was incorporated on July 21, 1916.

Blythe, California, is an isolated city in the northern end of the Palo Verde Valley of the Colorado River on the Arizona border. It is at the junction of Interstate 10 and U.S. highway 95.

Located in the Lower Colorado Valley of the Sonoran Desert, the region consists of sandy or gravely plains, low mountains, sand dunes and alkali sinks. Drainage channels, known as washes, store water to support trees and large shrubs along their banks.

Palo Verde Tree

The Palo Verde, "green branch" in Spanish,
is a common tree in the region.

Agriculturally based and heavily impacted by two state prisons and tourism, Blythe has a population of 21,500, and the general area about 30,300. The population more than triples during the winter months, with the arrival of Snowbirds, visitors seeking relief from cold climate in other parts of the country and Canada.

The Colorado River Recreation Area extends from Yuma, Arizona, to Lake Powell, a distance of about 650 miles. The area offers boating, fishing, hunting and other water sports. There are almost 95 miles of navigable water between Blythe and Imperial Dam in Yuma

Although California is remembered for its earthquakes, Blythe is one of the most seismically stable cities in the Western States. There has not been an earthquake entered here in over half a million years. Earthquakes centered as far away as the Los Angeles area are felt here, however, and the alluvial nature of the Palo Verde Valley soil intensifies the effect.
