Dig and Prepare Corner Post Holes

What happens here

Begin by digging the corner post holes. Use a gas-powered auger to quickly create the initial hole. If you encounter hard soil or rocks, a jackhammer will be necessary to break through the obstruction. Once the hole is to the desired depth, use a post hole digger to clear out loose soil and debris. After digging, add a layer of washed stone (gravel) to the bottom of the hole, then compact it thoroughly using a tamping tool (shown as a wooden post labeled 'TAMP'). This stone layer provides drainage and helps prevent frost heave, as demonstrated by comparing water drainage in clay versus clay with rocks.

Goal: Create properly sized and prepared post holes for corner posts.
