Blaine’s center stands about 40 ft above sea level. Within three miles the land runs from 0 ft to 420 ft, a difference of 420 ft: hilly country. Open water lies within three miles. The highest named summit within 15 miles is Holman Hill, about 390 ft, 8 miles south-southeast.
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 42×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
