Another morning (5am to noon) of cleaning up the site. Weeds grow everywhere every year and their roots can cause damage. Boring work in the sun so we're ready to do "real" work tomorrow. Pushing wheelbarrows of dirt and such like.
We came back a little early and learned how to work the level to take elevations. Working from a given fixed point whose exact distance above sea level is known we can measure the depth (or rather height) of any point where we are digging. This depth will change each day as we dig down and we will know the distance above sea level of every significant feature we find. And which feature we destroy or move as we dig down.
The weather yesterday was in the high 90s but cooler today. That's why we work only until noon.
