The total drainage area is 832,700 km² (321,500 mi²), of which 323,800 km² (126,300 mi²) is in Canada. By comparison, the total area is more than 25% larger than Texas or Alberta.  - California is the most populous state in the United States and the third most extensive by area. Located on the western (Pacific Ocean) coast of the U.S., California is bordered by the other U.S. states of Oregon, Nevada, and Arizona and shares an international border with the Mexican state of Baja California. The state capital is Sacramento. Los Angeles is California's most populous city, and the country's second largest after New York City.

Pidgeon thus became the second person , after Joshua Slocum , to do so .  - Photography is the science, art, application and practice of creating durable images by recording light or other electromagnetic radiation, either electronically by means of an image sensor, or chemically by means of a light-sensitive material such as photographic film.  - Harry Clifford Pidgeon (August 31, 1869  November 4, 1954) was an American sailor, a noted photographer, and was the second person to sail single-handedly around the world (1921-1925), 23 years after Joshua Slocum, a professional sea captain. Pidgeon was the first person to do this via the Panama Canal, and the first person to solo circumnavigate the world twice. On both trips, he sailed a 34-foot yawl named the "Islander", which Pidgeon constructed by himself. Prior to his first trip, Pidgeon had no prior experience sailing. He accounts for his adventures in his book, "Around the World Single-Handed: The Cruise of the "Islander"" (1932). Biography. Harry Clifford Pidgeon was born 31 August 1869 on a farm in Iowa. His father, Isaac Marion Pidgeon, was married 3 times and had a total of 12 children. The family were Quakers. At the age of 15, he set out for California where he found work on a ranch. Before long, he traveled north to Alaska, where he took a raft down the Yukon River and spent some time sailing among the small islands of the southeastern Alaskan coast. Later, he returned to California and traveled and worked in the Sierra Nevada mountains, taking up a career in photography.  - Sailing Alone Around the World is a sailing memoir by Joshua Slocum in 1900 about his single-handed global circumnavigation aboard the sloop "Spray". Slocum was the first person to sail around the world alone. The book was an immediate success and highly influential in inspiring later travelers.  - The Panama Canal is an artificial waterway in Panama that connects the Atlantic Ocean with the Pacific Ocean. The canal cuts across the Isthmus of Panama and is a key conduit for international maritime trade. There are locks at each end to lift ships up to Gatun Lake, an artificial lake created to reduce the amount of excavation work required for the canal, above sea level, and then lower the ships at the other end. The original locks are wide. A third, wider lane of locks was constructed between September 2007 and May 2016. The expanded canal began commercial operation on June 26, 2016. The new locks allow transit of larger, Post-Panamax ships, capable of handling more cargo.  - Alaska is a U.S. state located in the northwest extremity of North America. The Canadian administrative divisions of British Columbia and Yukon border the state to the east; its most extreme western part is Attu Island; it has a maritime border with Russia to the west across the Bering Strait. To the north are the Chukchi and Beaufort seasthe southern parts of the Arctic Ocean. The Pacific Ocean lies to the south and southwest. Alaska is the largest state in the United States by area, the 3rd least populous and the least densely populated of the 50 United States. Approximately half of Alaska's residents (the total estimated at 738,432 by the U.S. Census Bureau in 2015) live within the Anchorage metropolitan area. Alaska's economy is dominated by the fishing, natural gas, and oil industries, resources which it has in abundance. Military bases and tourism are also a significant part of the economy.  - Nova Scotia (Latin for "New Scotland"; French: "Nouvelle-Écosse") is one of Canada's three Maritime provinces, and one of the four provinces which form Atlantic Canada. Its provincial capital is Halifax. Nova Scotia is Canada's second-smallest province, with an area of , including Cape Breton and another 3,800 coastal islands. As of 2011, the population was 921,727, making Nova Scotia the second most-densely populated province in Canada with almost .  - A sloop (from Dutch "sloep", in turn from French "chaloupe") is a sailing boat with a single mast and a fore-and-aft rig. A sloop has only one head-sail: if a vessel has two or more head-sails, the term 'cutter' is used, and its mast may be set further aft than on a sloop.   - A yawl (from Dutch "jol") is a two-masted sailing craft similar to a sloop or cutter but with an additional mizzenmast (or mizzen mast) located well aft of the main mast, often right on the transom, or aft of the rudder post if the vessel has an inboard hung rudder. (A vessel with a larger mizzen located in a more forward position is called a ketch; see below: Yawl versus ketch.) The mizzen sail (smaller than the mainsail) is hoisted on the mizzen mast.  - Joshua Slocum (February 20, 1844  on or shortly after November 14, 1909) was the first man to sail single-handedly around the world. He was a Nova Scotian born, naturalised American seaman and adventurer, and a noted writer. In 1900 he wrote a book about his journey "Sailing Alone Around the World", which became an international best-seller. He disappeared in November 1909 while aboard his boat, the "Spray".  - A ketch is a sailing craft with two masts. The distinguishing characteristic of a ketch is that the forward of the two masts (the "mainmast") is larger than the after mast (the "mizzen"). Historically the ketch was a square-rigged vessel, most commonly used as a freighter or fishing boat in northern Europe, particularly in the Baltic and North seas. In modern usage, the ketch is a fore-and-aft rigged vessel used as a yacht or pleasure craft.    What entity does 'islander ' has the relation 'instance of' with?
