The highest point in Indianapolis is located in the cemetery. It is the burial spot of Hoosier poet James Whitcomb Riley. We were there with a group of teenagers for a guided tour. This would be a great spot for a summer time picnic.
If you come in the evening, be sure to bring a flashlight. Lighting is poor in many spots.
Our guide was very knowledgeable. He had the dirt on many of the notables buried there. The experience would not be remotely as fun without the guided tour.
There are renovations ongoing with the veteran's graves. So, it might be difficult to find specific graves.
You can search for names on the website. Given the age of the cemetery, if your family has been in the area for a long time, it is a good possibility that you have an ancestor buried here.
