Munch’s center stands about 980 ft above sea level. Within three miles the land runs from 910 ft to 1,040 ft, a difference of 130 ft: gently rolling country.
Under the town center the state geologic map shows Chengwatana volcanic rocks (mafic-volcanic), from the Mesoproterozoic, 1 to 1.6 billion 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 52×. 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, siltstone. Age: Mesoproterozoic, 1 to 1.2 billion years old. About 11 mi of the line.
Mafic-volcanic. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 10 mi of the line.
Sandstone, siltstone, shale. Age: Middle Cambrian to Cambrian, 487 to 521 million years old. About 2 mi of the line.
Basalt. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 0.8 mi of the line.
Volcanic. Age: Mesoproterozoic, 1 to 1.2 billion years old. About 0.3 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale.
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 Munch reaches the Gulf of America by way of the Kettle, the Saint Croix and the Mississippi: about 1,900 river miles.
Lakes on the way: Lake Pepin and Lake Mallalieu 175.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Munch; river miles along the main stem, rounded.
