Celebrate Fungus February by helping to document the diversity of fungi at Roy's Redwoods! Led by local mycologists, we will document and collect any fungi we encounter using iNaturalist.

Learn about the history of pets on Alcatraz, including the "Puppy Steps," and in other prisons today.

Help tend to the health of the Presidio’s historic forests.
