Wichita ? Federal officials are studying whether to designate the old Chisholm and Great Western cattle trails in Kansas as national historic trails.

The National Park Service scheduled a meeting Thursday evening in Wichita to let residents learn more and offer opinions on the possibility.

Millions of cattle were led from south Texas over the Chisholm and Great Western trails to railroad sites in Kansas and Nebraska between the 1860s and 1880s. The trails encompass about 2,500 miles of land routes in Texas, Oklahoma, Kansas and Nebraska.

Thursday’s public meeting takes place from 5 p.m. to 7 p.m. at the Wichita-Sedgwick County Historical Museum.
