At 552 feet above sea level this oblong knoll rises to the highest elevation in the area. Known as Houston's Mound as early as the 1830s, it afforded Native Americans, pioneers, and soldiers a view of the surrounding terrain. William T. Sadler (1797-1884) acquired land here which included the mound in the 1820s. Sadler, San Jacinto battle veteran and a respected land surveyor, is credited with establishing the mound as a survey benchmark. Sadler and a number of other surveyors used the mound to verify boundaries between Houston County and counties to its north and east. Sesquicentennial of Texas Statehood 1845 - 1995
