The early emigrants going west on the Oregon-California Trail and Santa Fe Trail came through Johnson County, Kansas. Diary entries describe the terrain. Two of the most common campsites were Sapling Grove, known today as Comanche Park, 8210 Grant in Overland Park, and Indian Creek/Flat Rock Creek, 13120 W. 103rd in Lenexa. Three other campsites were Elm Grove (also known as Caravan Grove), Lone Elm (also known as Round Grove), and Bull Creek (near the point where the Santa Fe Trail and the Oregon-California Trail diverge).
