Mount Signal and view of the Imperial Valley,
from vintage promotional literature (date unknown)
"Out of the unutterable desolation of the Colorado desert, Imperial Valley
lifted itself by it's bootstraps. Water was brought through canals from the
Colorado river and 20,000 people followed it and made their homes amid the
miraculous garden thus created. Property values—thirty cents was a fair
estimate twelve years ago—have gone beyond forty millions. Both population
and values will treble in Imperial county in the next twelve years"
