Michael,

I have quite a few photos and some transcribed reports, etc., online at www.exploresouthernhistory.com. Just click the "Battlefields and Forts" link and you will see it under Arkansas. There are also sections on the pre and post Prairie Grove actions at Cane Hill, Dripping Springs, Van Buren, etc.

I also recently did an extensive online tour of the battlefield on my blog at http://civilwararkansas.blogspot.com.

Best,
Dale
