No, there’s no better place since the ground is lined with clay soil everywhere. But since you’re using the clay to make stone blocks - either flagstone or cobblestone - you could be more efficient by targeting blocks that yield cobblestones. In POIs, you’ll find big boxy blocks wrapped in blue plastic tarp material. Harvest these with your shovel to get cobblestone rocks.
