These well-defined axe grinding groves are found on the sandstone bed of Camp Fire Creek. The grooves were formed by Aboriginal people when sharpening axes (or forming axe blanks). Rubbing the axe blanks would sharpen the stone into a more useful tool, and the process would also wear the sandstone, leaving these markings. These sites are typically found near water, as the water was added to make the stone more abrasive. Sites like this will fade in time due to erosion of the sandstone - please help them last as long as possible by not walking on, or close to the grooves.
