Summary

Net accretion on the reef has been very slow. With a mere 20 minutes of bottom times at depths of 130ft, there is not a lot of time to ponder 10,000 years of development! Scientists have taken core samples and determined the formation of the canyon probably began about 10,000 years ago. http://www.aoml.noaa.gov/general/lib/CREWS/Cleo/St.%20Croix/salt_river170.pdf
