The book I am looking for is one I checked out from the Louisville free public library in the 1960s.
The story was about a family moving west in a covered wagon. (This is not the Laura Ingalls Wilder story)
The family faced hardships and trials. It was a children’s chapter book with an orange cover that I believe had a covered wagon on the cover.
I know chimney rock was mentioned as a landmark in the book. I have looked many times for this book and would like to read it again. In contrast to the little house books, it was a bit more graphic, mentioning things like animal skeletons and tombstones along the trail.
It was fascinating and dramatic. I know this is vague, but would truly appreciate if you could find it. It has been gone from LFPL for many, many years.
