By Lee Foster Summer entices the connoisseur of California’s best beaches to the coast north and south of San Francisco. Whether you want to bronze your skin, marvel at tide pools, escape from urban life, or simply restore your lungs in the bracing salt air, the nearby beaches offer something for everyone. If you think you already know the roughly 250 miles of coast between Point Arena and Carmel, peruse the following selections. You may have overlooked these well-known and lesser-known beaches, all true delights. Moreover, some beaches also boast features that may be new to you, such as an improved hiking trail between Bodega Head and Bodega Dunes. If you haven’t recently explored the beauty of the coast, many aspects beckon throughout the year. For example, marvel at the salubrious spring and fall sunlight with its visual clarity. Or imbibe the pensive fogs of summer. On the other hand, savor the invigorating storms of winter as the pageant of the seasons unfolds. This article covers beaches north of San Francisco. A companion piece looks at best beaches south of The City. Limantour Beach at Point Reyes, about 50 miles north Limantour would get my vote as the single most inviting beach on the Northern California coast. Firstly, this length of lovely tan sand is so long. Secondly, the setting is totally pristine. The backdrop of wooded hillsides is alluring. You are right in a national park property with little intruding outside presence. Access is also excellent, with a large and available parking lot behind the beach, so this beach is for everyone. A sense of seclusion and wildness pervades the Point Reyes area, putting you far from Highway 1 and the noise or speed of any automobiles. Limantour is at the end of the road west to the coast as you enter the Point Reyes National Seashore region. Stop at the informative Visitor Center to orient yourself to Point Reyes and get a national parks map/brochure of the entity. A short list of California’s best beaches will likely include Limantour. Heart’s Desire Beach, about 54 miles north Point Reyes is prime beach country, with McClures and already-mentioned Limantour among the good choices. If the weather is windy or chilly, and you want a warmer and more protected setting, Heart’s Desire is a good place to consider. Heart’s Desire Beach is in Tomales Bay State Park on the more-protected east side of the peninsula. To reach Heart’s Desire Beach, drive into Point Reyes and turn onto Pierce Point Road to the clearly marked entrance of Tomales Bay State Park. To clarify, the road proceeds north, passing clusters of bay, madrone, and oak trees. Further, a road to the right enters the Tomales Bay Park. In short, you arrive at a protected cove, which is complete with a grassy area and picnic tables, restrooms, and an agreeable wooded setting. Heart’s Desire Beach offers the best ocean swimming in California north of San Francisco. The beach is ample and the ocean floor recedes gradually. Rip tides and sleeper waves are unknown. The water warms to as high as 80 degrees by the end of summer. Consequently, for both adults and children, this is an ideal sunning and swimming beach. Heart’s Desire Beach is protected from wind, with the fog hanging up on the ridge. When the rest of the coast is foggy and windy, Heart’s Desire will sometimes be sunny. Hiking at Tomales Bay From Heart’s Desire Beach you can also hike south along Tomales Bay to more secluded beaches, such as Pebble Beach (a half-mile) and Shell Beach (4 miles). Moreover, in this park you make the acquaintance of unusual bishop pines, which flourish here as an ancient forest. This pine species needs fire to open its cones and germinate the seeds. However, fires have been suppressed here, so the forest grows older. An established tule elk herd can be seen if you drive farther out on Pierce Point Road. This big game animal, so abundant in early California, survived a close brush with extinction and now climbs back to safe and stable numbers. Inverness offers several good bed and breakfast lodgings, such as Ten Inverness Way. Drive-in campers sometimes use the Samuel P. Taylor State Park, which locates you in the redwoods along the route in. Camping sites in state parks can be reserved. Backpack campers favor the walk-in Coast Camp or Wildcat Camp, both on the sea bluffs in Point Reyes National Seashore. A Czech restaurant at Inverness has a reputation for tasty dishes, such as chunks of lamb in paprika. Try Vladimir’s. Bodega Head and Bodega Dunes Beach, about 70 miles north Bodega Head and Bodega Dunes present an elemental, rugged coast, plus expansive sandy beaches. Above all, Bodega features the most impressive sand dunes in Northern California. The sandy beaches at Bodega Dunes extend for miles along the ocean. At Bodega Head, small pocket beaches can be found below the jutting, west- facing bluffs. If there is a short list of California’s best beaches with dunes, Bodega Dunes will probably be on it. To get to Bodega Head, turn west at Bodega Bay along Westshore Road and skirt the bay. You pass day-use Westshore Park, an access point to dig for littleneck, Washington, and gaper clams in Bodega Bay. At the end of the road, Bodega Head, you’ll find a parking lot, restrooms, access to the pocket beaches, and a hiking trail. Booking.com From the bluffs at Bodega Head, you can gaze north and south along the rugged coast, communing with the rocky shoreline. Bodega Head amounts to one of the most inspiring vistas along the coast. You can thread your way from the bluffs to the small pocket beaches for a picnic or sunning. Moreover, a trailhead sign alerts you to the 3-mile hiking trail linking Bodega Head with the miles of shifting sand dunes to the north. These dunes amount to a sand wilderness. Seeded European beach grass prevents the dunes from migrating freely. Walk north on this loose-sand trail for as long as you wish, allowing time for your walk back. The trail passes a University of California Biological Research station, but the tide-pool and population studies are not open for public scrutiny. Limantour Beach at Point Reyes National Seashore, just north of San Francisco. Bodega Dunes Campground After you’ve perused this splendid rocky promontory, for a direct route to the dunes, return to Highway 1, drive north a half mile, and turn west into the Bodega Dunes Campground. A boardwalk allows you to cross the dunes to the glorious, expansive beach. The boardwalk and restrooms have wheelchair access. The beach is for walking and viewing rather than swimming because of treacherous sleeper waves and rip tides. Eight miles of crisscrossing trails in the sand dunes behind the beach afford plenty of hiking opportunities. In other words, the beach environment at Bodega Head and Bodega Dunes has sufficient variety to please almost everyone. The Bodega area beaches are part of the Sonoma Coast State Beaches entity. Chain link fences recall the era when the site might have become a nuclear power plant. In winter, if you’re looking for a whale-watching platform, keep Bodega Head in mind. The Fisherman Festival in April is one of the area’s major celebrations. Lodging, Camping, and Seafood The Chanslor Ranch, a quarter-mile north of the dunes entrance, is a bed and breakfast that rents horses for riding in the dune area. Bodega Dunes Campground is a close-up location amidst the dunes, beach grass, and cypress trees, but with no direct access to the beach. The campground boasts an amenity favored by many campers–hot showers. One good camp-on-the-beach situation is Doran Beach, a county camping park, whose lovely shore-side sites are doled out on a first-come basis. Fresh seafood, such as locally caught sole or salmon, is the specialty at a Bodega restaurant known as The Tides Wharf. Bodega Bay hosts the largest fishing fleet between San Francisco and Eureka. Goat Rock Beaches, about 77 miles north Goat Rock Beaches, at the mouth of the Russian River, extend out on a peninsula between the river and the ocean. Watch waves crash against the rock pedestals, called sea stacks. View sunsets from this west-facing beach. Collecting driftwood art at the mouth of the Russian River occupies some travelers here. (The park staff encourages driftwood collecting because the wood debris becomes a potential fire hazard to roofs in the town of Jenner. Periodic burning reduces the uncollected volume.) To get to Goat Rock Beaches, which are not visible from the road, watch for the clearly marked sign and take State Park Road off Highway 1. The grassy bluffs overlooking Goat Rock Beaches make excellent picnic sites. At the beaches you’ll find a string of parking lots with access to the beach. The northern edge puts you closest to the mouth of the Russian River.

A variety of Riparian habitats 5. Mixed Evergreen Forest 6. Redwood Forest 7. North Coastal Scrub and Prairie 8. Coastal Beach, Marsh, and Tidal Communities B. Environmental Factors Climatic zones you will encounter include the somewhat “continental” climate of the Sacramento Valley, characterized by cool, wet winters with frequent winter fog (a result of cold air subsidence off the Sierras and entrapment in the Valley by the Coast Ranges), and long, dry, hot summers. Even more continental climates are characteristic of regions much further inland, e.g., Ohio. Really extreme continental climates occur in Central Asia and Siberia. Continental climates are so called because as you move inland away from the ocean, the moderating effect of the ocean on temperature leads to more extremes inland. The Coast Ranges are characterized by somewhat less extreme, but still highly variable, conditions of temperature and precipitation as they are in a zone of transition between the more Continental climate of the Valley and the highly Maritime climate of the Coast. The climate along the Coast is dominated by the cool waters of the Pacific Ocean and the California Current which flows south along this part of our coast. The ocean acts as a buffer and greatly reduces the extremes in temperature characteristic of the Sacramento Valley but also increases the amount of moisture in the air, increasing relative humidity.

  • David E. Pesonen: the Battle for Bodega Head Stacey Olson
    David E. Pesonen: The Battle for Bodega Head Stacey Olson Individual Exhibit Senior Division (Exhibit: 477 student composed words) (Process Paper: 496 words) I decided to research David E. Pesonen and the battle for Bodega Head when I learned that PG&E had intended to build a nuclear power plant on Bodega Head in the 1960s. Initially, I was uncertain about choosing a local history topic, but after some research I decided that Pesonen’s leadership had a significant legacy far beyond Sonoma County. Pesonen’s leadership style enabled a grassroots protest to defeat the largest power company in the country. Through my research I’ve discovered that the legacy of this victory extended beyond the issue of nuclear power, influenced the modern environmental movement, and became a model for participatory democracy. I started my research by visiting the Sonoma State University Regional History Collection and looking at documents and photographs. I accessed special reports and oral histories at the Bancroft Library and the National Archives and Records Administration. My best secondary source was Critical Masses by Thomas Wellock. I also found useful documents at the Eisenhower Presidential Library and the Nuclear Regulatory Commission. Interviews were an integral source of information. I interviewed David Pesonen, Doris Sloan, and journalists who covered the battle. My interview with David Pesonen was key to understanding his leadership style and why he was significant. Beyond my interviews, my best primary source was A Visit to Atomic Park by David Pesonen. I balanced my research in several ways. For PG&E’s perspective, I researched the demands for energy, the Atoms for Peace initiative, and interviewed a local citizen who wanted the power plant.

    What if I told you last year there were 2,412,151 cigarette butts or 1,739743 food wrappers all collected from beach cleanups. Shocking, right? Well here’s one more: enough balloons were collected to lift a great white shark according to Ocean Conservancy in 2017. All that trash would still be on the beaches if people like you didn’t help. This year International Coastal Cleanup is Saturday, September 15, 2018. There are cleanups taking place all over the world; many in Sonoma County. So, choose your beach or river and come out and make a difference. Let’s try and get all the trash out before the rains come.

  • JETTIES at BODEGA HARBOR Orville T. Magoon1, Donald D. Treadwell2, and Paul S. Atwood3 Bodega Harbor, a Lagoon Connected to Bode
    JETTIES AT BODEGA HARBOR Orville T. Magoon1, Donald D. Treadwell2, and Paul S. Atwood3 To create and maintain a navigable entrance for small craft between the Pacific Ocean and the natural lagoon now referred to as Bodega Harbor, the construction of two rubble-mound jetties and the associated dredging of interior channels were authorized by the United States Congress in the late 1930s. The jetties were built by the United States Army Corps of Engineers in the early 1940s. Elements of the planning, design, construction, monitoring, and maintenance of the jetties are discussed herein. Keywords: rubble-mound jetties; long-term performance; monitoring; maintenance; Bodega Bay; Bodega Harbor INTRODUCTION Bodega Harbor, a lagoon connected to Bodega Bay and the Pacific Ocean, is located on the California coast of the United States about 50 miles north of San Francisco. The Pacific Ocean areas offshore of Bodega Bay are excellent for both commercial and recreational fishing. However, the natural unimproved entrance to Bodega Harbor, both shallow and unstable, was very difficult to navigate safely. The project undertaken in the early 1940s by the United States government to improve the situation included two entrance channel jetties, a bulkhead to help retain the natural sandspit, and dredging of interior channels and turning basins. Figure 1 is an aerial view of the jetties, the sandspit, a portion of the dredged channels, and the seaward (western) end of the peninsula known as Bodega Head. Figure 1. Aerial View of Jetties and Dredged Entrance Channel at Bodega Harbor PHYSICAL AND GEOLOGIC SETTING The climate at Bodega Harbor in western Sonoma County is temperate and there is little variation between summer and winter temperatures with few days falling below freezing.
