Utah towns list more on the Register than most of the country (a typical Utah town has 3.0 per 10,000 residents, the U.S. 2.4), so South Jordan’s 1.2 sits near the middle of its state (47% of Utah towns have fewer) while its 10 historic buildings outnumber those of 76% of U.S. towns.
How sure. Graded on any two of the three inputs instead, the letter would range from D to C+. The pre-1940 share (±0.2 points) is firm at this size. Two sources give 1859.

What stands out about South Jordan’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
The first known inhabitants were members of the Desert Archaic Culture, who were nomadic hunter-gatherers. From around 400 to 1350 AD, the Fremont people settled into villages and farmed corn and squash. Changes in climatic conditions to a cooler, drier period and the movement into the area of ancestors of the Ute, Paiute, and Shoshone, led to the disappearance of the Fremont people. When European settlers arrived, no permanent Native American settlements were in the Salt Lake Valley, but the area bordered several tribes – the territory of the Northwestern Shoshone to the north, the Timpanogots band of the Utes to the south in Utah Valley, and the Goshutes to the west in Tooele Valley.
In 1859, according to Wikidata. South Jordan’s post office opened in 1877, and the census of 1940 counted 869 people here.
