If it's like the chattahoochee I've seen around here, just wait a year and it will peel off by itself! Just kidding, sort of.
This stuff is a layer of epoxy with rocks mixed in. The epoxy can form a heck of a bond, or it can delaminate easily depending on how it was installed. Your best bet is to rent a mechanical chipper/scraper such as is used to remove tile. You can get one at just about any tool rental facility. Be aware that it can also chip up the concrete under the epoxy too.
That being said, do you know the condition of the concrete under the epoxy? Usually, people apply this stuff to hide damaged concrete. After you remove the epoxy rock, you may find bad concrete that you can't do anything else with. It may be cheaper and easier to do a complete tearout of the slab.

Cool River Rock Removal

Thanks for the info. Our concrete is in good condition, but the rocks are just flaking off and we have holes in it so it might be easier to remove than we think. We have removed a bit of it with pressure washer. If you have any other ideas, please pass along. Thanks again!

If having success with pressure washer, you might want to aid the pressure with some scraping. Depending on how well the rock layer is bonded, you might be able to scrape off with a hoe or assist with chisel, taking care not to damage concrete. There are scrapers and pneumatic chisels available at rental centers.
