I have not read anything specifically on the karst topography of the canyon, however, he following has information regarding both karst topography (in general) and Cocconino Sandstones from a Creationist perspective. Answers in Genesis has a karstologist that may be able to give you more information.

Thank you for the links, I'll certainly read them.
