Join park staff for a demonstration and park ranger talk about the park's steam powered donkey engine. Engines such as these were used both ashore and aboard ship for loading cargo, raising anchor and setting sails. This program involves steaming up the boiler and operating this historic piece of machinery. The engine will be running 11am-4pm.
The park ranger talk will be at 1pm or 3:30pm. Call 415-447-5000 for details.
*No talk will be scheduled for 9/13/14.
