Thomas Jefferson's landholdings in Albemarle County totaled some 5,000 acres. To manage this vast estate, Jefferson divided the land into separate "farms." The area surrounding the planter's dwelling constituted the "home farm"; for Jefferson, this was Monticello mountain. Outlying lands were divided into manageable parcels known as "quarter farms" and were run by resident overseers.
The mountain that Thomas Jefferson named Montalto is a part of the Carters Mountain range, and is today sometimes known as Brown's Mountain. It is located about three miles southeast of Charlottesville and south/southwest of Monticello, being separated from that mountain by the "Thoroughfare Gap." The elevation is 1,278 feet and it rises 410 feet above Monticello.
