Muscadine vineyard with a thunderhead in the distance. Orange County, North Carolina.
And here is a closeup image where you can the definite size difference where the overflow stream entered. The area to image above and left of the field notebook was overwashed.
It is subtle. But you can also see a little bit of scour in the area where the overwash occured.
Where did the smaller gravels go? Thats a great question, and its too squishy to poke around and look right now. It could be under a mudpatch now on the driveway, it could be in the lawn or maybe even washed into the woods.
Tropical Storm Chantal provided just a terrific opportunity to see #geology in action.
Here is our gravel driveway, sloping from right to left. At image center, an overflowing came onto the driveway from the woods.
Right at the field notebook location, you can see where the smaller gravels in the driveway to the left have been mobilized away by the incoming stream. [1/2]
Very small crab spider on a wood trellis post in the garden protecting its egg sac. Screw head for scale.
(I was very careful retwining the trellis. All good!)
Video of a small bird (Northern parula) that wants to hang out at our French door window.
(It brought larvae in its beak later that afternoon. I gave it the thumbs up of appreciation of its hunting prowess.)
Our neighborhood is getting some new culverts, so of course I had to pose...
"That's all, folks!"

From my upcoming book.
"Fluvial Geomorphology of my Gravel Driveway."
(Just kidding on that one.)
