A testament of Bird Rock’s recently collapsed geologic namesake, something as familiar as a rock can define and add character to a community. And as Kendra Hartmann revealed in this week’s Page 1 story, “Nothing is forever,” La Jolla’s coastline is continuously evolving, each day losing something it once had. In the past century, local historians have noted, La Jolla has parted with several one-of-a-kind rocky landmarks. That’s just part of nature’s course. But La Jolla, being both artistically inclined and geologically unique, doesn’t have to say “good-bye” to formations such as “Bird Rock,” “Cathedral Rock” and “Alligator Head” forever. La Jolla is full of artistic gems, and there are even a number of public art projects in the works around La Jolla, including about a dozen murals by the La Jolla Community Foundation. Adding a series of monuments or sculptures — the most enduring of art forms — to the community’s constant agenda would be a noble idea. If not to let La Jolla’s unique geologic features live on through art, such a project sure would provide nice photo ops.
