Goldsworthy at the Presidio has been extended to July 19. This free exhibit offers insights into Andy Goldsworthy’s Spire - a sculpture near the Arguello Gate created from mature trees felled as the Presidio’s declining forest is gradually replanted. Preparatory sketches, photographs by the artist of spires he has created at other sites, and a 12-foot model of the Presidio spire are on display. A short program of film and video clips, and maps offer information about Goldsworthy, site-based art, and the Presidio Trust’s reforestation efforts. Goldsworthy at the Presidio runs Wednesday to Sunday, 11 am to 5 pm. It is located in Building 49 (adjacent to the Presidio Officers’ Club on the Main Post).

Last chance! The Water+Color exhibition, sponsored by the California Watercolor Association, ends May 24. One hundred paintings selected from a large pool of entries submitted by artists from around the nation are on display.

Some of the Presidio’s most beautiful landscapes are rarely seen by the public. The historic Fort Scott district is home to several gems: Dragonfly Creek, the Presidio Nursery (where 60,000 native plants are grown each year), the gardens of the officers’ homes on Kobbe Avenue, and a WWII victory garden that is now tended by park residents. This month, Presidio experts will lead a guided stroll through these areas, explaining their past, present, and future. Join us for Hidden Gardens and Landscapes of Fort Scott on Saturday, May 9. A few spots are still open for the 9 am tour. Visit the web for details, and call (415) 561-5418 to RSVP. Co-sponsored with The Garden Conservancy.
