In 1995, William A. Frassanito, a former military intelligence analyst, documented a comprehensive photographic analysis, which places the location of the platform with the position of specific modern headstones in [[Evergreen Cemetery (Adams County, Pennsylvania)|Evergreen Cemetery]]. According to Frassanito, the extant graves of Israel Yount (died 1892)({{Coord|39|49.180|N|77|13.845|W| type:landmark_region:US-PA_dim:30|name=grave of Israel Yount (d. 1892)}}), John Koch (died 1913)({{Coord|39|49.184|N|77|13.847|W| type:landmark_region:US-PA_dim:30|name=grave of John Koch (d. 1913)}}), and George E. Kitzmiller (died 1874)({{Coord|39|49.182|N|77|13.841|W| type:landmark_region:US-PA_dim:30|name=grave of George E. Kitzmiller (d. 1874)}}) are among those which occupy the location of the 1863 speaker's stand.{{sfn|Frassanito|1995|p=160-167}}
