Warner’s center stands about 490 ft above sea level. Within three miles the land runs from 410 ft to 1,540 ft, a difference of 1,130 ft: steep hill country. The highest named summit within 15 miles is Mount Kearsarge, about 2,910 ft, 7 miles north-northwest.
The section below crosses 7 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 10×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Granodiorite. Age: Early Devonian, 394 to 422 million years old. About 15 mi of the line.
Granofels, calc-silicate-rock, pelitic-schist. Age: Silurian, 422 to 428 million years old. About 3 mi of the line.
Quartzite, metasedimentary. Age: Silurian, 422 to 445 million years old. About 2 mi of the line.
Metaclastic. Age: Silurian, 434 to 445 million years old. About 1 mi of the line.
Quartz-diorite, tonalite, granodiorite. Age: Early Devonian, 394 to 422 million years old. About 1 mi of the line.
Pelitic-schist, metasandstone. Age: Silurian, 434 to 445 million years old. About 1.0 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 1 smaller unit along the line are not listed.
Heights from Copernicus GLO-90 (a surface model: it includes buildings and tree canopy); summits from USGS GNIS; rivers from USGS NHDPlus HR; rock from the USGS State Geologic Map Compilation.
A raindrop that lands in Warner reaches the Atlantic Ocean by way of the Warner, the Contoocook and the Merrimack: about 120 river miles.
100 miles of the trip are on the Merrimack.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Warner; river miles along the main stem, rounded.
Warner has a warm-summer humid continental climate. Summer afternoons average 80° in July; winter nights fall to about 13° in January. About 49 inches of rain fall in a normal year.
Normals 1991–2020 and records since 1996 at Salisbury, 7 miles northeast. NOAA, through RCC-ACIS.
