I knew in advance from the forecast, heavy rain was coming.
Set up the tent in the only spot that had high ground. And as you can see in the photo, it was flatter than a pancake. The area above the rock wall was not available for camping.
Yup, I found the high ground, tent was not flooded out. Photo was deceptive, the grass was taller than the puddles were deep, thus some of the area that looks like it is grass is in fact an inch deep in water. Both of the adjacent sites were flooded.
Next day was heavy wind, stayed at that camp for three nights, which included the rain day and the wind day.
