The Gardner plate. Relief from Copernicus GLO-30; rivers and lakes from USGS NHD; watersheds from the USGS Watershed Boundary Dataset; roads and city limits from Census TIGER 2024.
91° on Nov. 14, 2008, the hottest reading for this week of the year since 1933. Next is 91° in 2018.
Gardner’s center stands about 80 ft above sea level. Within three miles the land runs from 30 ft to 90 ft, a difference of 60 ft: nearly flat ground.
Under the town center the state geologic map shows Reworked Cypresshead sediments (sand), from the Late Pliocene to Pleistocene, less than 3.6 million years old.
The section below crosses 3 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.
Sand, clay, dolostone. Age: Middle Miocene to Pliocene, 2.6 to 16 million years old. About 14 mi of the line.
Sand. Age: Late Pliocene to Pleistocene, less than 3.6 million years old. About 8 mi of the line.
Sand, clay. Age: Pleistocene to Holocene, less than 2.6 million years old. About 2 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale.

A raindrop that lands in Gardner reaches the Gulf of America by way of Charlie Creek and the Peace: about 55 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Gardner; river miles along the main stem, rounded.
Gardner has a humid subtropical climate. Summer afternoons average 92° in July; winter nights fall to about 48° in January. About 52 inches of rain fall in a normal year.
On November 14 Gardner normally reaches 80° and falls to 56°. The record high is 91°, in 2018; the record low 35°, in 1968. The most rain on this date, 7.60 in, fell in 1997.
