Caracas (, Spanish: [kaˈɾakas]), officially Santiago de León de Caracas, abbreviated as CCS, is the capital and largest city of Venezuela, and the centre of the Metropolitan Region of Caracas (or Greater Caracas). Caracas is located across the Guaire River at the northern portion of the country, within the Caracas Valley of the Venezuelan coastal mountain range (Cordillera de la Costa). The valley is near the Caribbean Sea, separated from the coast by a steep 2,200-metre-high (7,200 ft) mountain range, Cerro El Ávila; to the south there are more hills and mountains. The Metropolitan Region of Caracas has an estimated population of almost 5 million inhabitants. The middle of the city remains Catedral, situated near Bolívar Square, although some consider the center to become Plaza Venezuela, located at the Los Caobos region.

Businesses in town include service companies, banks, and malls. Caracas has a mostly service-based market, besides some industrial action in its metropolitan area. The Caracas Stock Exchange and Petróleos de Venezuela (PDVSA) are headquartered in Caracas. PDVSA is the largest company in Venezuela. Caracas is also Venezuela's cultural capital, with many restaurants, theaters, museums, and shopping centers. Caracas has some of the tallest skyscrapers in Latin America, like the Parque Central Towers. The Museum of Contemporary Art of Caracas is one of the most important in South America.Caracas has among the highest per capita murder rates in the world, with 111.19 homicides per 100,000 inhabitants.

In geology, a boulder is a rock fragment with size greater than 256 millimetres (10.1 in) in diameter. Smaller pieces are called cobbles and pebbles. While a boulder may be small enough to move or roll manually, others are extremely massive. In common usage, a boulder is too large for a person to move. Smaller boulders are usually just called rocks (American English) or stones (In British English a rock is larger than a boulder). The word boulder is short for boulder stone, from Middle English bulderston or Swedish bullersten.In places covered by ice sheets during Ice Ages, such as Scandinavia, northern North America, and Siberia, glacial erratics are common. Erratics are boulders picked up by ice sheets during their advance, and deposited when they melt.

They are called "erratic" because they typically are of a different rock type than the bedrock on which they are deposited. One of them is used as the pedestal of the Bronze Horseman in Saint Petersburg, Russia. Some noted rock formations involve giant boulders exposed by erosion, such as the Devil's Marbles in Australia's Northern Territory, the Horeke basalts in New Zealand, where an entire valley contains only boulders, and The Baths on the island of Virgin Gorda in the British Virgin Islands. Boulder-sized clasts are found in some sedimentary rocks, such as coarse conglomerate and boulder clay. The climbing of large boulders is called bouldering.
