Boone East Marsh is adjacent to Masterson on the west and is divided by the east-west road.
Description:  This grassland/marsh complex is about 500 acres and is mostly in private ownership. The unique kettle/kame habitat still contains native prairie remnants and home to about 85 bird species during the nesting season. Northern harriers routinely nest here, as do bobolinks, grasshopper sparrows, and loggerhead shrikes. Bell's vireos, least and American bitterns, Forster's and black terns have all been found here in early spring. In dry springs, it is not unusual to find several hundred shorebirds concentrated here.
