87° on Nov. 14, 2005, the hottest reading for this week of the year since 1989. Next is 84° in 1989.
Winnsboro’s center stands about 520 ft above sea level. Within three miles the land runs from 430 ft to 580 ft, a difference of 150 ft: gently rolling country.
Under the town center the state geologic map shows Queen City Sand (siltstone, sandstone), from the Middle Eocene, 38 to 48 million years old.
The section below crosses 4 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 64×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Siltstone, sandstone. Age: Middle Eocene, 38 to 48 million years old. About 13 mi of the line.
Mudstone. Age: Late Paleocene to Early Eocene, 48 to 59 million years old. About 6 mi of the line.
Sandstone. Age: Eocene, 34 to 56 million years old. About 3 mi of the line.
Sandstone. Age: Eocene, 34 to 56 million years old. About 3 mi of the line.

A raindrop that lands in Winnsboro reaches the Gulf of America by way of Indian Creek, Big Sandy Creek and the Sabine: about 420 river miles.
Lakes on the way: Toledo Bend Reservoir and Sabine Lake.
150 miles of the trip are on the Sabine.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Winnsboro; river miles along the main stem, rounded.
