Sunburst’s center stands about 3,370 ft above sea level. Within three miles the land runs from 3,320 ft to 3,710 ft, a difference of 390 ft: rolling country. The highest named summit within 15 miles is Jerusalem Rocks, about 3,670 ft, 6 miles north-northwest.
Under the town center the state geologic map shows Kevin Member of Marias River Formation (shale, limestone, dolostone), from the Late Cretaceous, 84 to 90 million 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 20×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Shale, limestone, dolostone. Age: Late Cretaceous, 84 to 90 million years old. About 17 mi of the line.
Sandstone, siltstone, shale. Age: Late Cretaceous, 72 to 87 million years old. About 2 mi of the line.
Sandstone, siltstone, shale. Age: Late Cretaceous, 84 to 87 million years old. About 2 mi of the line.
Sandstone, siltstone, mudstone. Age: Late Cretaceous, 66 to 84 million years old. About 1 mi of the line.
Sandstone, sandstone-mudstone. Age: Late Cretaceous, 72 to 87 million years old. About 1 mi of the line.
