I had the privilege and honor of working with Dan at LL&E. He was the most well versed gentleman geologist I have ever known. I greatly benefitted from working with and knowing Dan and when he retired, I missed him. The science of geology is better for his being a part of it. With his passing, an era has also passed. He deeply loved his wife, his family, and his profession. May he rest in well-deserved peace.

I was a student of Dr. Arden at Georgia Southwestern College in the late 70’s and early 80’s. A brilliant man with a wit that was as sharp as a knife. He set the course for my life with his brilliance, passion and dedication to the young people in his charge. I am so disappointed I am just now aware of his passing. Thank you, Dr. Arden, you were a gift and a blessing. Tony Jordan
