It's a grass mulch in my back yard next to a swimming pool.. I do the cooking in a Weber or ceramic tray if I am doing coals on the bottom. Sometimes I only put coals on the top to finish the recipe as in these images. I do not recommend using a Dutch Oven in high fire conditions that include low humity and high winds. Sorry if these images portrayed that as OK.
