Lawrenceport’s center stands about 650 ft above sea level. Within three miles the land runs from 480 ft to 760 ft, a difference of 280 ft: rolling country. The highest named summit within 15 miles is Gobblers Knob, about 960 ft, 11 miles west-southwest.
Under the town center the state geologic map shows Sanders Group (limestone), from the Carboniferous, 324 to 359 million years old.
The section below crosses 6 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 41×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.

A raindrop that lands in Lawrenceport reaches the Gulf of America by way of the East Fork White, the White River, Big Bayou, the Wabash River Old Channel, the Old Channel Wabash, the Ohio and the Mississippi: about 1,340 river miles.
970 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Lawrenceport; river miles along the main stem, rounded.
Lawrenceport has a hot-summer humid continental climate. Summer afternoons average 85° in July; winter nights fall to about 21° in January. A normal year brings about 16 inches of snow; with the rain, that comes to about 48 inches of water.
On November 14 Lawrenceport normally reaches 54° and falls to 33°. The record high is 75°, in 1978; the record low 7°, in 2019. The most rain on this date, 1.77 in, fell in 1972.
Normals 1991–2020 and records since 1893 at Oolitic Purdue Ex Frm, 13 miles northwest. NOAA, through RCC-ACIS.
