The Sky Art Sculptures of Borrego Springs

Borrego Springs, California

Something more than the spectacular Anza-Borrego Desert State Park attracts visitors to the Borrego Valley in Southern California. People come from all around to see the amazing 130 full-sized metal sculptures here – many inspired by creatures that roamed this same desert millions of years ago. The artworks range from prehistoric mammals to historical characters, fanciful dinosaurs, and a 350-foot-long fanciful serpent. Drive through the roads that weave through the area – you’ll see sculptures of wild horses in a nearby field, sabertooth tigers in pursuit, and desert tortoises that seem as if they’re crawling through the brush.

Hot Deserts – Cold Deserts

In most modern classifications, the deserts of the United States and northern Mexico are grouped into four distinct categories.

Plant communities, in turn, are determined by the geologic history of a region, the soil and mineral conditions, the elevation and the patterns of precipitation. Three of these deserts — the Chihuahuan, the Sonoran and the Mojave — are called “hot deserts”. Read more …

Golden eagles are birds of open country, not forests, from desert grasslands to above timberline. They build large stick nests in trees or cliff walls where they have plenty of room to maneuver. Golden eagles are masters at soaring. Read more…
