What stands out about Green Grove’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
Some of the early European Americans to walk the six mile square that would become Green Grove were the U.S. government's surveyors. From 1845 to 1847 they surveyed the outline of the township on foot with chain and compass. Then others came back in January 1853 to survey all the section lines. When done, the deputy surveyor filed this general description:
This Township is nearly entirely(?) level a great part of it Swampy and unfit for cultivation. The part Which is not swamp is but little elevated above(?) Swamp, Soil 3rd(?) rate, thickly timbered with Pine, ? and Elm, very(?) free from undergrowth, but few Streams and those Small Except One Near the Northwest part of the Town. of Some Size that With all the rest bears N. West(?)
