The town of Bloomer is a 6-by-8-mile (9.7 by 12.9 km) rectangle in northwestern Chippewa County.

In July 1847, a team working for the U.S. government conducted the first survey of 6-mile (9.7 km) squares that would become Bloomer.

In September 1852, other crews marked all the section corners of the six mile squares, walking through the woods and wading the swamps, measuring with chain and compass.

[2][3] When done, the deputy surveyor filed this general description of the western six miles: This Township contains a large quantity of good Timber Pine Oaks & Sugar Maple are usually mixed throughout this Township.

The surface is mostly undulating (except for a few small swamps), and the soil is light, consisting of a few inches of leaf mould with a gravelly or rocky subsoil.
