Start by picking a flat spot away from anything that could catch fire. Dig a shallow circle about 3‑4 feet in diameter. Line the walls with the largest stones you can find, placing each stone snugly against the next so the gap is tight. Leave a gap at the base for the firewood; you can line that with smaller rocks to keep the heat focused. Once the ring is set, fill the bottom with a layer of sand or fine gravel so the fire doesn’t dig into the ground. Set a small wooden bench or a flat stone nearby for sitting, and lay a blanket or a few extra stones around it for a quiet area. Keep the fire small, use only dry wood, and have a bucket of water close in case you need to douse it. That’ll give you a focused heat source and a calm place to think.

Got it. Tight walls, bench set, water in range. Just keep the fire small, and you’re good.

Sounds like a plan. Stay sharp, keep it simple, and you’ll be fine.
