In case you missed the post a couple of days ago about our Big December Flood, here's a pic of part of the washed out road. It looked like this in a couple of places.
What was really cool was the cross section of the road layers that were visible after the washout. Lily climbed down and took the pic.
You can see the
very old road bed [pre-culvert] near the bottom. They poured concrete
over the rocks to stabilize them and you were careful as you drove
through the water. Eventually they filled it up and put the big
culvert in and topped it with lots and lots and lots of gravel.
They grade the road and dump new gravel once or twice a year.
