Whether you're camping in the woods or desiring to make a fire in your backyard, fire safety should always be number one. When conditions are dry, a fire can get out of hand quickly, a rock fire pit is a good way to decrease your chances of an accident happening. Putting together a rock fire pit isn't that hard.
Rake away any debris that is in the area where the fire pit is to be made. You should have about an area six feet in diameter cleared of any leaves or branches. This will help cut down on a fire starting outside of the pit once you get one started.
Gather up the rocks you plan on using. You should try to use medium to larger size rocks to make your fire pit, as they are more stable when stacked up upon each other. The type of rocks don't matter, as long as they are solid and don't crumble easily.
Figure out how big of an area you want to use for the fire itself. Start placing the rocks around the outside of this area in a circle. Place the larger rocks on the bottom, working your way around and placing the smaller ones on the upper portion. Try to make the rocks as closely fitted and stable as possible. You will probably want to have your rocks stacked approximately ten inches high off the ground.
Using cement, you can hold the rocks together. This would be used if you desire to have a rock fire pit that is relatively permanent. Of course this is more work, but your fire pit will have less chance of being knocked over. If you desire to have the rock fire pit for occasional or one time use, the simple way is probably better.
Stack some dried wood into the center of the rock fire pit. Light it and you have a fire. The rocks should remain in place and keep your fire safe from burning down the forest or something else. Sit back and enjoy the fire and your new creation.
