Bollinger Canyon Creek
Bollinger Canyon Creek is an approximately stream in Contra Costa County, California in the San Francisco Bay Area. It is a tributary of San Ramon Creek which is part of the Walnut Creek (Contra Costa County), Walnut Creek watershed. The creek derives its name from the surname of a family who settled in the area in the 19th century. Course Bollinger Canyon Creek begins as a number of ephemeral streams emitting from a Horst (geology), horst valley, Bollinger Canyon, in the highest reaches of the Berkeley Hills, in California's Inner Coast Ranges. The highest point in the drainage is around 2,000 feet above sea level. From a low divide which separates it with Las Trampas Creek, it runs southward through Bollinger Canyon, gradually descending in altitude until turning sharply to the east near Crow Canyon Road in San Ramon, California. It is joined by its only named tributary, San Catanio Creek. Shortly after, it is confined to concrete channels and it joins with San Ramon Creek ...

East Bay
The East Bay is the eastern region of the San Francisco Bay Area and includes cities along the eastern shores of San Francisco Bay and San Pablo Bay. The region has grown to include inland communities in Alameda and Contra Costa counties. With a population of roughly 2.8 million in 2024, it is the most populous subregion in the Bay Area, containing the second- and third-most populous Bay Area counties of Alameda (1.7 million) and Contra Costa (1.1 million). Oakland is the largest city in the East Bay by population and the third largest in the Bay Area. The city serves as a major transportation hub for the U.S. West Coast, and its port is the largest in Northern California. Increased population has led to the growth of large edge cities such as Alameda, Concord, Emeryville, Fremont, Hayward, Livermore, Pleasanton, San Ramon, and Walnut Creek. History and development Although initial development in the greater Bay Area focused on San Francisco, the coastal East Bay ...

Wild Boar
The wild boar (''Sus scrofa''), also known as the wild swine, common wild pig, Eurasian wild pig, or simply wild pig, is a Suidae, suid native to much of Eurasia and North Africa, and has been introduced to the Americas and Oceania. The species is now one of the widest-ranging mammals in the world, as well as the most widespread Suina, suiform. It has been assessed as least concern on the IUCN Red List due to its wide range, high numbers, and adaptability to a diversity of habitats. It has become an invasive species in part of its introduced range. Wild boars probably originated in Southeast Asia during the Early Pleistocene and outcompeted other suid species as they spread throughout the Old World. , up to 16 subspecies are recognized, which are divided into four regional groupings based on skull height and lacrimal bone length. The species lives in matriarchal societies consisting of interrelated females and their young (both male and female). Fully grown males are usually s ...

Coyote
The coyote (''Canis latrans''), also known as the American jackal, prairie wolf, or brush wolf, is a species of canis, canine native to North America. It is smaller than its close relative, the Wolf, gray wolf, and slightly smaller than the closely related eastern wolf and red wolf. It fills much of the same ecological niche as the golden jackal does in Eurasia; however, the coyote is generally larger. The coyote is listed as Least Concern, least concern by the International Union for Conservation of Nature, due to its wide distribution and abundance throughout North America. The species is versatile, able to adapt to and expand into environments modified by humans; urban coyotes are common in many cities. The coyote was sighted in eastern Panama (across the Panama Canal from their home range) for the first time in 2013. The coyote has 19 recognized subspecies. The average male weighs and the average female . Their fur color is predominantly light gray and red or fulvous int ...

Fog Moves Up Bollinger Canyon
Fog is a visible aerosol consisting of tiny water droplets or ice crystals suspended in the air at or near the Earth's surface. Reprint from Fog can be considered a type of low-lying cloud usually resembling stratus and is heavily influenced by nearby bodies of water, topography, and wind conditions. In turn, fog affects many human activities, such as shipping, travel, and warfare. Fog appears when water vapor (water in its gaseous form) condenses. During condensation, molecules of water vapor combine to make tiny water droplets that hang in the air. Sea fog, which shows up near bodies of saline water, is formed as water vapor condenses on bits of salt. Fog is similar to, but less transparent than, mist. Definition The term ''fog'' is typically distinguished from the more generic term ''cloud'' in that fog is low-lying, and the moisture in the fog is often generated locally (such as from a nearby body of water, like a lake or ocean, or from nearby moist ground or marshes). ...

Rocky Ridge, California
Rocky Ridge is a ridge in the Inner Coast Ranges in western Contra Costa County, California, in the San Francisco Bay Area. Being the second-highest mountain in the county, it is visible from much of the surrounding area. The ridge is a very prominent feature in the geography of the towns of Lafayette, Moraga and Orinda, California. Etymology The current name originates from the oddly-formed sedimentary rock outcrops that trace the crest of the ridge. The original Saclan name for the ridge has been lost, however the current managers of the ridge, the EBRPD and EBMUD, believe it was commonly traversed by native groups. Geography Rocky Ridge is the highest point in the Berkeley Hills, which are a generally north-south trending subrange of the Inner Coast Ranges named for the nearby city of Berkeley, California. The region has a cool-summer Mediterranean climate and frequently receives fog from the nearby Pacific Ocean. Winters are wet and mild, while the summers are ho ...
