LOWER WINDSOR TWP.-- Join local historian and archivist June Lloyd at 6 p.m. April 20 at Shank's Mare, 2092 Long Level Road, Lower Windsor Township, to learn more about "The 1801 Mapping of the Wild and Raging Susquehanna."

Lloyd will talk about Benjamin Henry Latrobe, who took on the daunting job of mapping the steep banks and rocky spillways of the Susquehanna before the building of the dams that now form Lake Clarke, Lake Aldred and Conowingo Pond.

While Latrobe is best known as one of the fathers of American architecture, his work surveying the Lower Susquehanna in 1801 has more impact on area residents today. Lloyd will share pictures of the early maps and a variety of information from the York County Historical Trust archives.

Cost, which includes dinner and speaker, is $36 for members and $40 for nonmembers.
