What drives Crystal River’s History grade
On its age, its old homes and the National Register, Crystal River is more historic than 38% of U.S. towns, #117 of 638 in Florida. Its National Register listings hold the grade up; its share of homes from before 1940 pulls it down.
C+
HistoryA character grade: shown, never part of Crystal River’s overall grade.
Few Florida towns list much on the Register (a typical Florida town has 0.0 per 10,000 residents, the U.S. 2.4), so Crystal River’s 5.5 sits above most of its state (82% of Florida towns have fewer) while its 2 listings outnumber those of 60% of U.S. towns.
How sure. Graded on any two of the three inputs instead, the letter would range from C− to B. The pre-1940 share is a Census survey estimate (±3.1 points). The founding year is the first post office, not a stated founding date.

What stands out about Crystal River’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
In the Pleistocene era, the land on which Crystal River is located was vastly different from today. The west coast of Florida is thought to have extended an additional 50 to 60 miles (80 to 97 km) into the Gulf of Mexico. During excavations for the Crystal River Nuclear Plant in 1969, scientists discovered rhinoceros and mastodon bones, as well as the shells of an extremely large armadillo and a large land tortoise.
Around 500 BCE mound-building Native Americans (possibly Deptford culture) built a settlement along the Crystal River, which in the present day is the Crystal River Archaeological State Park. It was abandoned prior to European colonization for unknown reasons. The Native American name for Crystal River was Weewahi Iaca.
