Canada's only Pacific province overnight had become Canada's only province. Once the initial panicked news cycle had blown over, the British Columbian government decided to take advantage of their independence. 'British' was dropped from the country's name, resettlement of the lost areas in the upper Columbia valley, Peace River and the Northern Rockies was encouraged and Stikine Territory was carved out in the northeast. While Columbia pursued their own path, the economies and politics of their neighbours south of the 49th parallel were much more interconnected as Seattle retained its status as the Pacific Northwest's economic and cultural hub, and people continued to cross the Washington-Oregon border daily for both work and leisure trips. Travel across the Washington-Idaho border was much more one way though as the counties of the Idaho panhandle struggled to support themselves without Boise and the major part of the state. As the situation deteriorated, Olympia found itself increasing involved in providing services to areas it wasn't taxing, thus the creation of a government in Coeur d'Alene became a priority. The need for further coordination between Olympia, Salem, Coeur d'Alene and the Oregonian settlements along the Snake River lead, in stages, to the creation of a federal government based in Seattle and known as Cascadia. With Cascadia's economy growing and the Snake River settlements being admitted as the state of Shoshone, the question of the relationship between Cascadia and Columbia came to be asked with increasing frequency. After decades of protracted negotiations Columbia finally acceded, albeit with many unique concessions granting much greater self-government. Following Columbia's admittance, Cascadia continued to expand eastwards across the Rocky Mountains, however their most recent territorial gain was far to the south as the few beleaguered survivors of Pitcairn, first contacted by Bajan fishermen, elected to put themselves under Seattle's administration.
The disappearance of all human structures outside California and Nevada had a major and immediate impact on the two states. Spanning the Colorado River, and hence the Nevada-Arizona border the Hoover Dam suddenly lost its southern half, with the remainder being rapidly destroyed by the flood waters of Lake Mead rushing downstream. The destruction of the Hoover Dam resulted in major power and water outages in Las Vegas and Los Angeles, with rectifying this and the damage to the lower Colorado valley stretching Sacramento and Reno's reserves beyond breaking point, with the later completely collapsing and accepting incorporation into California. Donations from Washington, Oregon and Columbia helped, but rebuilding the dam was a decades long project that soon became mired in accusations of corruption, partisanship and waste, leading to the withdrawal of international support and with it the souring of relations between Cascadia and California. Northern Californians and Nevadans also grew unhappy with what they saw as the the neglect of their communities to prop up the unstainable desert cities of the south. Grants of autonomy to Nevada and the now impoverished Vegas area did little to assuage the growing Nevadan nationalist movement with looked to follow the Mormons of Deseret and the Latinos of New Mexico in breaking away from California completely.
Although the flooding of the Colorado had been a major disaster for California, for the Mexicans of Baja, it finally brought much needed water to the Colorado delta, greening the north of the state. Baja's boom was short lived though as water management was reinstated further upstream and the Gila River valley and eastern coast of the Gulf of California were settled by both white and Latino Californians, forcing Bajans further down the peninsula. Latino settlement was disorganised and chaotic as the various different nationalities and groups struggled for both control and their own space, eventually coalescing into New Mexico, although many areas remained separate.
