75° on Nov. 12, 2012, the hottest reading for this week of the year since 1948. Next is 70° in 1982.
Lawrence’s center stands about 590 ft above sea level. Within three miles the land runs from 400 ft to 770 ft, a difference of 370 ft: rolling country. The highest named summit within 15 miles is Eagle Mountain, about 2,140 ft, 14 miles south-southeast.
Under the town center the state geologic map shows Potsdam Sandstone, from the Cambrian, 487 to 497 million years old.
The section below crosses 5 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 12×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Sandstone. Age: Cambrian, 487 to 497 million years old. About 9 mi of the line.
Amphibolite, gneiss. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 5 mi of the line.
Dolostone. Age: Cambrian to Early Ordovician, 471 to 542 million years old. About 5 mi of the line.
Dolostone, limestone. Age: Early Ordovician, 471 to 487 million years old. About 4 mi of the line.
Charnockite, gneiss. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 2 mi of the line.

A raindrop that lands in Lawrence reaches the St. Lawrence River by way of Allen Brook, Trout Brook, the Deer River, the Saint Regis, the Raquette and the Saint Lawrence: about 30 river miles. The St. Lawrence carries it on to the Atlantic.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Lawrence; river miles along the main stem, rounded.
Lawrence has a warm-summer humid continental climate. Summer afternoons average 81° in July; winter nights fall to about 6° in January. About 34 inches of rain fall in a normal year.
On November 14 Lawrence normally reaches 45° and falls to 28°. The record high is 69°, in 1959; the record low 8°, in 1971. The most rain on this date, 1.12 in, fell in 1975.
Normals 1991–2020 and records since 1948 at Massena International Airport, 15 miles north-northwest, 390 ft lower. NOAA, through RCC-ACIS.
