Step 6 – Dry Creek Bed: Building the Creek Bed
Because of their size (boulders are defined as anything bigger than 16” in diameter) and the fact that they need to be partially buried in the ground, it’s best to place boulders first. Place them at random, asymmetric focal points throughout the creek bed, remembering to choose an odd number for a natural look.
Once you have set the boulders in the perfect position, you can now begin to fill the creek bed with cobble. Remember to use the smallest pieces in the middle or bottom of the creek bed, fill in the sides with the mid-sized cobble, and save the largest for the top or outer edges. This placement mimics the way river rocks would be gently moved over time by water and settle naturally.
