Moses Lake North’s center stands about 1,170 ft above sea level. Within three miles the land runs from 1,040 ft to 1,230 ft, a difference of 190 ft: gently rolling country. The highest named summit within 15 miles is Black Butte, about 1,550 ft, 15 miles north.
Under the town center the state geologic map shows Younger glacial drift (fine-detrital, coarse-detrital), from the Pleistocene, less than 2.6 million years old.
The section below crosses 4 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 39×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Fine-detrital, coarse-detrital. Age: Pleistocene, less than 2.6 million years old. About 16 mi of the line.
Silt. Age: Pleistocene, less than 2.6 million years old. About 5 mi of the line.
Basalt. Age: Late Oligocene to Early Pliocene, 3.6 to 28 million years old. About 2 mi of the line.
Silt, sand. Age: Pleistocene, less than 2.6 million years old. About 1 mi of the line.

A raindrop that lands in Moses Lake North reaches the Pacific Ocean by way of Moses Lake, Potholes Reservoir, Lower Crab Creek and the Columbia: about 470 river miles.
Lakes on the way: Lake Umatilla, Potholes Reservoir and Moses Lake.
210 miles of the trip are on the Columbia.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Moses Lake North; river miles along the main stem, rounded.
