Guide to San Francisco Bay Area CreeksGallinas & Miller CreeksThis map is a composite of maps from the early 1900s.The creek names in these watersheds are very confusing. In Gallinas marsh there is a large slough named Gallinas Creek. It extends inland as far as the lagoon below the Marin County Civic Center. Upstream of that were several intermittent tributaries draining the Santa Margarita Valley. But, in Gallinas Valley runs Miller Creek, which has a separate mouth at the northern edge of Gallinas Marsh. USGS Topographic Map Composite; Courtesy of HISTOPO |
