History
The Utah Territory authorized creation of San Juan County on February 17, 1880, with territories annexed from Iron, Kane, and Piute counties. There has been no change in its boundaries since its creation. Monticello was founded in 1887, and by 1895 it was large enough to be designated the seat of San Juan County.
Geography
San Juan County lies at the southeastern corner of the state of Utah. Its borders coincide with the borders of the states of Colorado, New Mexico, and Arizona with Utah. The convergence point of these borders, Four Corners Monument, is located at the extreme southeastern corner of the county.
The county's terrain generally slopes to the west and the south, with its highest point, Mount Peale, at above sea level. The county has a total area of , of which is land and (1.4%) is water. It is the largest county by area in Utah.
The county's western and southern boundaries lie deep within gorges carved by the Colorado and San Juan Rivers. Tributary canyons, cutting through rock layers of the surrounding deserts, have carved the land up with chasms, cliffs and plateaus. In the center of the county are Cedar Mesa, Comb Wash, Natural Bridges and Hovenweep National Monuments. Canyonlands National Park lies mostly within the county borders. The Eastern side of Glen Canyon National Recreation Area / Lake Powell is also in the county.
The Blue (Abajo) Mountains and the La Sal Mountains exceed in elevation. Both ranges are covered with lush forests, in stark contrast to the scenery below. The elevation change within the county is from nearly in the La Sal Mountains to at Lake Powell, a difference of about .
The county's towns lie primarily on a north–south axis along U.S. routes 191 and 163 from La Sal in the north to Monument Valley in the south.

Politics and Government
San Juan County has supported Republican presidents since voting for Wendell Willkie in 1940. It supported a Democrat for president in 1896 (William Jennings Bryan), 1916 (Woodrow Wilson), and 1936 (Franklin D. Roosevelt). Though a Republican vote currently secures elections, the area has voted less Republican than the rest of Utah in many national elections. In 2004, for example, George W. Bush won 60.02% in San Juan County versus 71.54% in the state as a whole. In 2020, Democrat Joe Biden needed 6.13% more votes to win the county from Donald Trump, who secured 51.2% in the county as opposed to 58.13% in the state as a whole. The county is more competitive at the state level due to its high Native American population, which leans Democratic. Notably, the county voted for the Democratic candidates in the 1988 and 2000 gubernatorial elections, both of which Republican candidates won.
Federally mandated commissioner districts put many Navajo voters in one district. The San Juan County Board of Commissioners has been majority white for many years. In 2016, a Federal District Court decision found voting districts violated the 1965 Voting Rights Act and the U.S. Constitution. Before the 2016 court decision, the county used an at-large voting system to elect commissioners.
In 2018, the first ever majority-Navajo commission was seated. Two of the three county commissioners, Willie Grayeyes and Kenneth Maryboy, are board members of Utah Diné Bikeyah, which supported the creation of Bears Ears National Monument. In a 2019 special election, Proposition 10, which would have changed the structure of the county government to include five county commissioners, was blocked needing 153 more populous votes. The proposition, spearheaded by Blanding Mayor Joe Lyman, was characterized by opponents as an effort to undermine the Navajo-majority county commission. Mayor Joe Lyman characterized the proposition as a way to restore representation to Blanding, the county's largest city. He states, "I don't like how we arrived at the commissioners we have because it felt like a judicial appointment," and that, "the vote is very evenly split."
As of March 2020, efforts were underway to bring municipal water and electrical service to the 29-home Diné (Navajo) community of Westwater, which has existed for decades with neither just outside the city limits of Blanding.
