A portion of the Santa Clara Heights near Truman Drive has grappled with the danger of sliding land for over 30 years and despite numerous efforts by the City of Santa Clara to stop it, there is still no solution in sight.

Geologic history and cause

The Santa Clara Heights is built upon the Santa Clara Bench, a natural plateau bordered by the Santa Clara River Valley to the southwest and a small tributary stream to the northeast.

Petrified forest member is a weak rock that swells quickly and moves easily when wet.
