Newhope’s center stands about 760 ft above sea level. Within three miles the land runs from 570 ft to 900 ft, a difference of 330 ft: rolling country. The highest named summit within 15 miles is Raspberry Mountain, about 2,360 ft, 13 miles northwest.
Under the town center the state geologic map shows Stanley Shale (black-shale, sandstone, siltstone), from the Carboniferous, 324 to 359 million years old.
The section below crosses 8 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 15×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Black-shale, sandstone, siltstone. Age: Carboniferous, 324 to 359 million years old. About 11 mi of the line.
Sandstone, shale. Age: Carboniferous, 299 to 324 million years old. About 6 mi of the line.
Sandstone, marlstone. Age: Early Cretaceous, 100 to 145 million years old. About 3 mi of the line.
Sandstone. Age: Silurian, 422 to 445 million years old. About 2 mi of the line.
Novaculite. Age: Late Devonian to Carboniferous, 324 to 384 million years old. About 1 mi of the line.
Coarse-detrital, fine-detrital. Age: Pleistocene, less than 2.6 million years old. About 0.6 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 2 smaller units 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 Newhope reaches the Gulf of America by way of Fallen Creek, the Muddy Fork, the Little Missouri, the Ouachita, the Black River, the Red River, the Atchafalaya and the Lower Atchafalaya: about 640 river miles.
310 miles of the trip are on the Ouachita.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Newhope; river miles along the main stem, rounded.
