These massive floods occurred during the last ice age and filled the Willamette Valley with 300 to 400 feet (91 to 122 m) of water. Before American settlers began arriving in the 1800s, the land was inhabited for many centuries by two bands of indigenous Chinook people – the Multnomah and

By the early 20th century, the city had lost its reputation as a "sober frontier city" and garnered a reputation for being violent and dangerous. Between 1900 and 1930, the city's population tripled from nearly 100,000 to 301,815. During World War II , it housed an "assembly center" from which up to 3,676 people of Japanese descent were dispatched to internment camps in

Large numbers of pioneer settlers began arriving in the Willamette Valley in the 1840s via

The cumulative effect of the floods was to excavate 210 cubic kilometres (50 cu mi) of loess , sediment and basalt from the channeled scablands of eastern Washington and to transport it downstream. These floods are noteworthy for producing canyons and other large geologic features through cataclysms rather than through more typical gradual processes . In addition, Middle and Early Pleistocene Missoula flood deposits have been documented to comprise parts of

The height of the ice dam typically approached 610 metres (2,000 ft), flooding the valleys of western Montana approximately 320 kilometres (200 mi) eastward. It was the largest ice-dammed lake known to have occurred. The periodic rupturing of the ice dam resulted in the Missoula Floods – cataclysmic floods that swept across eastern Washington and down

According to a 2017 survey, several of these faults were characterized as "probably more of a hazard" than the Cascadia subduction zone due to their proximities to population centers, with the potential of producing magnitude 7 earthquakes . Notable earthquakes that have impacted the Portland area in recent history include

The age of these deposits is demonstrated by the presence of multiple interglacial calcretes interbedded in these glaciofluvial deposits, sequences of sediments with normal and reverse magnetostratigraphy , optically stimulated luminescence dating, and unconformity truncated clastic dikes . Based upon these criteria, Quaternary geologists estimated that
2904-560: The urban heat island effect. Neighborhoods outside of the downtown core, especially in slightly higher elevations near the West Hills and Mount Tabor , can experience a dusting of snow while downtown receives no accumulation at all. The city has experienced a few major snow and ice storms in its past, with extreme totals having reached 44.5 in (113 cm) at the airport in 1949–50 and 60.9 in (155 cm) at downtown in 1892–93. Summers in Portland are warm, dry, and sunny, though
2992-766: The 1940s and 1950s. In 1957, Life magazine published an article detailing the city's history of government corruption and crime, specifically its gambling rackets and illegal nightclubs. The article, which focused on crime boss Jim Elkins , became the basis of a fictionalized film titled Portland Exposé (1957). In spite of the city's seedier undercurrent of criminal activity, Portland enjoyed an economic and industrial surge during World War II. Ship builder Henry J. Kaiser had been awarded contracts to build Liberty ships and aircraft carrier escorts, and chose sites in Portland and Vancouver, Washington , for work yards. During this time, Portland's population rose by over 150,000, largely attributed to recruited laborers. During

Downtown Portland straddles the banks of the Willamette River, which flows north through the city center and separates the city's east and west neighborhoods. Less than 10 miles (16 km) from downtown, the Willamette River flows into the Columbia River, the fourth-largest river in the United States, which divides Oregon from Washington state. Portland
3520-631: The Pleistocene cannot be estimated with any confidence. Although Lake Missoula likely was the source of many of the Ancient Cataclysmic Floods, the fragmentary nature of the older deposits within the Hanford formation makes precise determination of the precise origin of the floods that deposited them very difficult. The Cordilleran ice sheet originating in British Columbia expanded out of

In 1889, The Oregonian called Portland "the most filthy city in the Northern States", due to the unsanitary sewers and gutters, and, at the turn of the 20th century, it was considered one of the most dangerous port cities in the world. The city housed
