This month's Trip in Time goes swimming in the pools, plunges, lakes and beaches of the East Bay.

These little ones beat the heat of August 1949 by frolicking in the shallower waters of Lake Anza in Tilden Regional Park in Berkeley.

Trip in Time photos are selected by Oakland Tribune librarian Veronica Martinez.
