I can't describe it, and photos do a poor job. This is one of the most effective memorial or sculpture I have ever seen. You have to walk through it to achieve the effect. There are is so much to say about it but I'll limit myself to one major point that can't be seen. From the outside it apears vast and expancive, but as you walk into it you begin to sink and loose sight of the whole but become increasinly aware of it's depth as well.
