Oljato, once listed separately from Monument Valley, is now folded into the single Oljato-Monument Valley CDP by the Census Bureau, and White Mesa Village is the same White Mesa community, not a second place.<\/p>\n ZIP Codes<\/h2>\nThe county’s smallest and most remote communities — Navajo Mountain, Fry Canyon, Clay Hills Crossing, and several Navajo Nation chapter settlements — share the ZIP of their nearest post office town rather than carrying one of their own.<\/p>\n Geography<\/h2>\nSan Juan County is a high-desert plateau of canyons, mesas, and laccolithic mountains — the Abajo (Blue) Mountains rise above 11,000 feet near Monticello and Blanding, while the county’s southern half drops into the deep sandstone canyons of the San Juan River and Lake Powell on the Colorado River. Cedar Mesa, the Bears Ears buttes, and the Navajo Nation’s Monument Valley sit within its borders, and the Four Corners Monument — the only point in the United States where four states meet — anchors its southeastern tip.<\/p>\n San Juan County borders Grand County to the north, Emery County<\/a> to the northwest, Wayne County<\/a> and Garfield County<\/a> to the west, and Kane County<\/a> to the southwest, all within Utah. Across the state line it borders Montezuma County, Colorado to the east and Apache and Navajo Counties, Arizona to the south, with San Juan County, New Mexico meeting it at the Four Corners point to the southeast.<\/p>\n The 2020 census counted 14,518 residents, with Blanding (3,509) and Monticello (1,935) the two largest communities. More than half the county’s population lives within the Navajo Nation, whose reservation covers most of the county south of the San Juan River. Median household income runs well below the Utah median of $93,421, reflecting the county’s remote, largely reservation-based economy. At roughly 1.8 people per square mile, San Juan is one of the most sparsely populated counties in Utah.<\/p>\n Tourism drives much of the county’s economy, anchored by Bears Ears National Monument, Natural Bridges National Monument, Monument Valley Navajo Tribal Park, and the Lake Powell marinas at Halls Crossing. Government employment, the San Juan School District, and Utah State University’s Blanding campus are major employers in Blanding and Monticello, alongside ranching, uranium and oil-and-gas extraction with a long history in the county, and Navajo Nation tribal programs serving the reservation communities in the south.<\/p>\n San Juan County was organized by the Utah Territorial Legislature on February 17, 1880, taking its name from the San Juan River, which Spanish explorers had earlier named in honor of Saint John. Mormon pioneers reached the area that same winter via the Hole-in-the-Rock expedition, a grueling wagon crossing of the Colorado River canyons that founded Bluff. The county’s more recent history includes 20th-century uranium mining booms around Monticello and La Sal, and, in 2016, the creation and subsequent boundary reduction of Bears Ears National Monument, a still-contested chapter in the county’s public-lands story.<\/p>\n US Highway 191 runs the length of the county north–south through Monticello and Blanding, meeting US 163 near Bluff and continuing to Mexican Hat and Monument Valley; US 491 and State Route 95 provide the main routes west toward Lake Powell and Natural Bridges.<\/p>\n The nearest commercial airport is Moab–Canyonlands Regional Airport, about an hour north of Monticello; the county also operates small general-aviation airfields at Blanding and Monticello.<\/p>\n Where is San Juan County, Utah?<\/strong> What is the population of San Juan County?<\/strong> How big is San Juan County?<\/strong> What is the San Juan County seat?<\/strong> How many towns and communities are in San Juan County?<\/strong> |
