<P> White Rock is named for a distinctive large white boulder on its beach near the promenade , a glacial erratic that migrated south during the last glaciation . The 486 - ton granite boulder was kept white by shellfish - eating seabirds whose guano covered the rock , so much so that 19th - century sailors used it as a beacon . However , it is now kept white through monthly applications of white paint by the city parks department , and has been a popular graffiti target for over thirty years . </P>
