Elkhorn Slough (pronounced "slew") sits on the central California coast about 100 miles south of San Francisco, in the middle of the curve of Monterey Bay. A narrow arm of the sea, it reaches inland, crooking north at the elbow and ending in a thin finger. Unknown to most visitors, this small embayment is adjacent to a huge underwater chasm - the Monterey submarine canyon. Stretching more than 25 miles out into the Pacific and more than a mile down from the water's surface, the Monterey Canyon could hold the Grand Canon of the Colorado River.
From open beaches at the Monterey Bay's edge, to pickleweed marshes and mudflats, to woodlands and prairies in the uplands - the Elkhorn Slough watershed is home to a great variety of habitats. This setting provides home and shelter to an amazing an abundant variety of plants and animals. The Slough Life section of our website provides an overview of these habitats and inhabitants. We encourage you to check back regularly as we add new species to this online resource.
