It is the Coachella Valley in Southern California. It's sandy in most places. The sand is beige, though the rocky hillsides in some places are many beautiful hues. Most natural vegetation is low growing, and unless the spring is a dry one, colorful displays of sand verbena, cactus and wildflowers (some tiny and very delicate) are visible many places. It's part of the Colorado desert, commonly called the low desert, as contrasted with the high desert, the Mojave.
Most of the valley floor is below sea level, with the shoreline of an ancient sea visible on the mountainsides along the Salton Sink, in which the Salton Sea is located. If the surface of the Salton Sea were at sea level, much of the Coachella Valley would be covered by it, and people could have shoreline property in Palm Springs!
I do have pictures, but none in digital form...
My bike is an old one, a 1983 Honda V45 Magna (750cc). A road bike, powerful and smooth engine. Riding in 124 degrees F on the hot freeway surface is something I'll never do again. I did it that one time to feel what it's like-no need to repeat! I was very happy to be able to escape the heat by heading up to much cooler elevations-no way was I going to ride home back through the valley.
A month or so after that I got a job in Palm Springs and commuted every day-in a car without air conditioning. I got used to it eventually.
I rode my bike in milder weather for a while but got tired of replacing helmet face shields from windblown sand. Not to mention getting tired of leaning hard to the left while traveling on the straight road off the freeway at 50 miles per hour when the wind was blowing hard. Made me a bit nervous, it did, what with cars coming the other way and all.
