Here is the entire progress of my hole, minus the first 3 days, when it was really more of a depression rather than a full-fledged hole. Enjoy. I recommend playing something nostalgic while viewing, like the perhaps the theme from Cheers or When We Were Kings.

Still eating root. Sawdust trimmings falling in. This is a clearly still a substandard hole.

Now this is getting somewhere. That is sweet, sweet dirt you can see on the bottom. That troublesome new root is coming in the top of the frame...




This is the same hole, but 180 degree different angle.

Hey now... Starting to look nicely cavernous.











Same reverse shot as yesterday. Just look at the serious foot of solid hard wood I have gone through so far.

There she is, in all her depthly glory. A post hole for the ages!











Final depth: 27.5 inches. I decided against shooting for the full 30 as it was going to make the final post too short. So this is closer to 30% underground rather than 1/3, as recommended on bags of Quikcrete everywhere.
