The Weeks Act is a federal law (36 Stat. 961) enacted by the United States Congress on March 1, 1911. Introduced by Massachusetts Congressman John W. Weeks and signed into law by President William Howard Taft , the law authorized the United States Secretary of Agriculture to "Examine, locate and recommend for purchase ... such lands within the watersheds of navigable streams as ... may be necessary to the regulation of flow of navigable streams...." This meant that the federal government would be able to purchase private land if the purchase was deemed necessary to protect rivers ' and watersheds ' headwaters in the eastern United States . Furthermore, the law allowed for land acquired through this act to be preserved and maintained as national forest territory. Six years earlier, the Transfer Act of 1905 transferred control over the federal forest reserves from the United States General Land Office of the Department of the Interior to the Department of Agriculture and its Forest Service . Responsibility for land purchased through the Weeks Act was not given to former Chief Forester Gifford Pinchot because he resigned from the National Forest Reservation Commission in 1907, with the stipulation that he would only resign if he could appoint his successor. This stipulation led to the Forest Service's tradition of picking a head with forestry knowledge. With the land acquired through the Weeks Act, Pinchot's successor obtained the power to issue permits for water power development on National Forests. The Weeks Act appropriated $ 9 million to purchase 6 million acres (24,000 km) of land in the eastern United States.
95-580: The Weeks Act also provided measures for more cooperation between federal and state governments in regard to fire control. This legislation was heavily influenced by the fire season of 1910 because it wreaked havoc across the western United States, particularly in Idaho , where 85 people, including 72 firefighters, were killed in fires and more than 3 million acres (12,000 km) of land and roughly 8,000,000,000 board feet (19,000,000 m) of timber were destroyed by fires that year. This year's fire season alone put

There was vagueness and confusion over the nature of the 1843 Organic Law, in particular, whether it was constitutional or statutory . In 1844, a new legislative committee decided to consider it statutory. The 1845 Organic Law made additional changes, including allowing
285-410: A difficult start as a territory, including the chaotic transfer of the territorial capital from Lewiston to Boise , disenfranchisement of Mormon polygamists upheld by the U.S. Supreme Court in 1890, and a federal attempt to split the territory between Washington Territory, which gained statehood in 1889, a year before Idaho, and the state of Nevada which had been a state since 1864. Idaho

The Oregon Country was originally claimed by Great Britain, France, Russia, and Spain;
570-601: A provisional government at Champoeg . Political pressure in the United States urged the occupation of all the Oregon Country. Expansionists in the American South wanted to annex Texas , while their counterparts in the northeast wanted to annex the Oregon Country. It was seen as significant that the expansions be parallel, as the relative proximity to other states and territories made it appear likely that Texas would be pro-slavery and Oregon against slavery. In

This theory was endorsed in Oregon Geographic Names as "the most plausible explanation". George Vancouver explored Puget Sound in 1792. Vancouver claimed it for Great Britain on June 4, 1792, naming it for one of his officers, Lieutenant Peter Puget . Alexander Mackenzie
6935-477: The name when he met a little girl named Ida . Since the name appeared to be fabricated, the U.S. Congress ultimately decided to name the area Colorado Territory instead when it was created in February 1861, but by the time this decision was made, the town of Idaho Springs, Colorado had already been named after Willing's proposal. The same year Congress created Colorado Territory, a county called Idaho County
7030-573: The new territory on March 2, 1853. Alexander Ross , an early Scottish Canadian fur trader, describes the lower reaches of the Willamette River, in the south of the Oregon Country (known to him as the Columbia District): The banks of the river throughout are low and skirted in the distance by a chain of moderately high lands on each side, interspersed here and there with clumps of wide spreading oaks, groves of pine, and
7125-454: The northern border of the region and often erroneously attributed to Polk's campaign. The goal of the slogan was to rally Southern expansionists (some of whom wanted to annex only Texas in an effort to tip the balance of slave/free states and territories in favor of slavery) to support the effort to annex Oregon Country, appealing to the popular belief in manifest destiny . The British government, meanwhile, sought control of all territory north of
7220-505: The participation of British subjects in the government. Although the Oregon Treaty of 1846 settled the boundaries of U.S. jurisdiction, the provisional government continued to function until 1849, when the first governor of Oregon Territory arrived. A faction of Oregon politicians hoped to continue Oregon's political evolution into an independent nation, but the pressure to join the United States prevailed by 1848, four months after
7315-638: The raw product for processed cheese , is in Gooding, Idaho . It has a capacity of 120,000 metric tons per year of barrel cheese and belongs to the Glanbia group. Hewlett-Packard has operated a large plant in Boise since the 1970s, which is devoted primarily to LaserJet printers production. Idaho has a state gambling lottery , which contributed $ 333.5 million in payments to all Idaho public schools and Idaho higher education from 1990 to 2006. Tax
7410-614: The region. The Hudson's Bay Company, which had previously discouraged settlement as it conflicted with the lucrative fur trade, belatedly reversed its position. In 1841, on orders from Sir George Simpson , James Sinclair guided more than 100 settlers from the Red River Colony to settle on HBC farms near Fort Vancouver. The Sinclair expedition crossed the Rockies into the Columbia Valley , near present-day Radium Hot Springs , British Columbia, then traveled southwest down
7505-607: The relatively isolated Idaho Panhandle , is closely linked with Eastern Washington , with which it shares the Pacific Time Zone —the rest of the state uses the Mountain Time Zone . The state's south includes the Snake River Plain (which has most of the population and agricultural land), and the southeast incorporates part of the Great Basin . Idaho is quite mountainous and contains several stretches of
7600-414: The river at all. The growing numbers of American settlers along the lower Columbia gave Simpson reason to question the long-term security of Fort Vancouver. He worried, rightfully so, that the final border resolution would not follow the Columbia River. By 1842, he thought it more likely that the United States would at least demand Puget Sound , and the British government would accept a border as far north as
7695-462: The river from side to side in the form of an irregular horseshoe, over which the whole body of water falls at one leap down a precipice of about forty feet, called the Falls . After living in Oregon from 1843 to 1848, Peter H. Burnett wrote: [Oregonians] were all honest, because there was nothing to steal; they were all sober, because there was no liquor to drink; there were no misers, because there
7790-596: The self-identified religious affiliations of Idahoans over the age of 18 in 2008 and 2014 were: According to the Association of Religion Data Archives , the largest denominations by number of members in 2010 were The Church of Jesus Christ of Latter-day Saints with 409,265; the Catholic Church with 123,400; the non-denominational Protestants with 62,637; and the Assemblies of God with 22,183. In 2020,
7885-600: The south. A Late Upper Paleolithic site was identified at Cooper's Ferry in western Idaho near the town of Cottonwood by archaeologists in 2019. Based on evidence found at the site, first people lived in this area 15,300 to 16,600 years ago, predating the Beringia land bridge by about a thousand years. The discoverers emphasized that they possess similarities with tools and artifacts discovered in Japan that date from 16,000 to 13,000 years ago. The discovery also showed that
7980-817: The state. These tribes include the Shoshone-Bannock, the Shoshone-Paiute, the Coeur d’Alene, the Kootenai and the Nez Perce. Note: Births in table don't add up, because Hispanics are counted both by their ethnicity and by their race, giving a higher overall number. Religious self-identification, per Public Religion Research Institute 's 2022 American Values Survey According to the Pew Research Center on Religion & Public Life,
8075-461: The top countries of origin for Idaho's immigrants were Mexico, Canada, the Philippines, China and Germany. Idaho's population increased by 17.3% from 2010 to 2020, the second fastest rate of growth of any state that decade. Nampa, about 20 miles (30 km) west of downtown Boise, became the state's second largest city in the late 1990s, passing Pocatello and Idaho Falls. Nampa's population
8170-577: The west, Nevada and Utah are to the south, and Montana and Wyoming are to the east. Idaho also shares a short border with the Canadian province of British Columbia to the north. The landscape is rugged, with some of the largest unspoiled natural areas in the United States. For example, at 2.3 million acres (930,000 ha), the Frank Church-River of No Return Wilderness Area is the largest contiguous area of protected wilderness in
8265-605: The winter when cloud cover, humidity , and precipitation are at their maximum extent. This influence has a moderating effect in the winter where temperatures are not as low as would otherwise be expected for a northern state with predominantly high elevations. In the panhandle, moist air masses from the coast are released as precipitation over the North Central Rockies forests , creating the North American inland temperate rainforest . The maritime influence
8360-623: Was Kullyspell House , established on the shore of Lake Pend Oreille in 1809 by David Thompson of the North West Company for fur trading. In 1812 Donald Mackenzie , working for the Pacific Fur Company at the time, established a post on the lower Clearwater River near present-day Lewiston. This post, known as "MacKenzie's Post" or "Clearwater", operated until the Pacific Fur Company was bought out by
8455-489: Was claimed by both the United States and Great Britain until the United States gained undisputed jurisdiction in 1846. From 1843 to 1859, present-day Idaho was under the de facto jurisdiction of the Provisional Government of Oregon . When Oregon became a state in 1859, what is now Idaho was situated in what remained of the original Oregon Territory, designated as the Washington Territory. Between 1849 and
8550-500: Was corrected with a 2007 amendment. Areas north of the Salmon River , including Coeur d'Alene , Moscow , Lewiston , and Sandpoint , are in the Pacific Time Zone , which contains less than a quarter of the state's population and land area. Idaho's climate varies widely. Although the state's western border is about 330 miles (530 km) from the Pacific Ocean, the maritime influence is still felt in Idaho; especially, in
8645-412: Was created in eastern Washington Territory . The county was named after a steamship named Idaho , which was launched on the Columbia River in 1860. It is unclear whether the steamship was named before or after Willing's claim was revealed. Regardless, part of Washington Territory, including Idaho County, was used to create Idaho Territory in 1863. Idaho Territory would later change its boundaries to
8740-538: Was one of the hardest hit of the Pacific Northwest states during the Great Depression . Prices plummeted for Idaho's major crops: in 1932 a bushel of potatoes brought only ten cents compared to 1919 for $ 1.51, while Idaho farmers saw their annual income of $ 686 in 1929 drop to $ 250 by 1932. In recent years, Idaho has expanded its commercial base as a tourism and agricultural state to include science and technology industries. Science and technology have become
8835-413: Was recorded at Island Park Dam on January 18, 1943. As of 2018: The United States Census Bureau determined Idaho's population was 1,900,923 on July 1, 2021, a 21% increase since the 2010 U.S. census . Idaho had an estimated population of 1,754,208 in 2018, which was an increase of 37,265, from the prior year and an increase of 186,626, or 11.91%, since 2010. This included a natural increase since
8930-586: Was the first European to cross North America by land north of New Spain, arriving at Bella Coola on what is now the central coast of British Columbia in 1793. From 1805 to 1806, Meriwether Lewis and William Clark explored the territory of the United States on the Lewis and Clark Expedition . David Thompson , working for the Montreal -based North West Company , explored much of the region beginning in 1807 with his friend and colleague Simon Fraser , following
9025-544: Was under 29,000 in 1990 and grew to over 81,000 by 2010. Located between Nampa and Boise, Meridian also experienced high growth, from fewer than 10,000 residents in 1990 to more than 75,000 in 2010 and is now Idaho's third largest city. Growth of 5% or more over the same period has also been observed in Caldwell , Coeur d'Alene , Post Falls , and Twin Falls. From 1990 to 2010, Idaho's population increased by over 560,000 (55%).
