==Geography==
According to the [[U.S. Census Bureau]], the county has an area of {{convert|702|sqmi}}, of which {{convert|667|sqmi}} are land and {{convert|35|sqmi}} (5.0%) are water.<ref name="GR1">{{cite web|url=https://www.census.gov/geographies/reference-files/time-series/geo/gazetteer-files.html|publisher=[[United States Census Bureau]]|access-date=April 23, 2011|date=February 12, 2011|title=US Gazetteer files: 2010, 2000, and 1990}}</ref> Unlike much of Florida, most of Leon County has rolling hills, as part of Florida's [[Red Hills Region]]. The highest point is {{convert|280|ft|m}}, in the northern part of the county.

===Geology===

Leon County encompasses [[basement rock]] composed of [[basalt]]s of the [[Triassic]] and [[Jurassic]] from ~251 to 145 million years ago interlayered with [[Mesozoic]] [[sedimentary rock]]s. The layers above the basement are [[carbonate rock]] created from dying [[foraminifera]], [[bryozoa]], [[mollusk]]s, and [[coral]]s from as early as the [[Paleocene]], a period of ~66—55.8 Ma.<ref>{{Cite web|url=http://www.clas.ufl.edu/users/guerry/GLY4155/sp35/Fgs35.HTM|archive-url=https://web.archive.org/web/20091228042634/http://www.clas.ufl.edu/users/guerry/GLY4155/sp35/Fgs35.HTM|url-status=dead|title=Geology of Florida, University of Florida|archive-date=December 28, 2009}}</ref>

During the [[Eocene]] (~55.8—33.9 Ma) and [[Oligocene]] (~33.9—23 Ma), the [[Appalachian Mountains]] began to uplift and the erosion rate increased enough to fill the [[Gulf Trough]] with [[quartz sand]]s, [[silt]]s, and [[clay]]s via rivers and streams. The first sedimentation layer in Leon County is the Oligocene [[Suwannee Limestone]] in the southeastern part of the county as stated by the [[United States Geological Survey]] and Florida Geological Survey.<ref>{{Cite web|url=https://archive.usgs.gov/archive/sites/sofia.usgs.gov/|title=South Florida Information Access (SOFIA) -- USGS Greater Everglades Ecosystems Science|website=archive.usgs.gov|access-date=October 2, 2019}}</ref>

The [[Early Miocene]] (~23.03—15.7 Ma) sedimentation in Leon County is [[Hawthorn Group]], [[Torreya Formation]] and [[St. Marks Formation]] and is found in the northern two-thirds of the county.

The [[Pliocene]] (~5.332—2.588 Ma) is represented by the Miccosukee Formation scattered within the Torreya Formation.

Sediments were laid down from the [[Pleistocene]] epoch (~2.588 million—12 000 years ago) through the [[Holocene]] epoch (~12,000—present) and are designated Beach ridge and trail and undifferentiated sediments.

====Terraces and shorelines====
During the Pleistocene, what would be Leon County emerged and submerged with each glacial and [[interglacial]] period. Interglacials created the county's topography.
