My Saguaro is a least 200 years old with 6 arms and a few offshoots. Recently, the entire base of the tree up to the arms seems to have lost its outer skin and is brown in color. Am I losing this tree or is this normal?

As far as I know, this is not normal. The plant is very old and may simply be dying from plain old age. But I would encourage you to contact your local extension service and discuss this with them. They may have information on how to save this beautiful plant. Here is the contact information for your local office: https://extension.arizona.edu/maricopa
