After the flood
After Passage Creek receded following last week’s flood, I went down to the bridge and the floodplain to have a look around. Here’s a little bit of what I saw… Let’s start at the bridge itself.

The time we didn’t get stranded by the flood
Last spring, I made two visits, six days apart, to Veach Gap, a small water gap superimposed on the Massanutten Synclinorium.

At Gros Ventre, the landslide-dammed lake overtopped the debris and caused a catastrophic flood which killed 6 people in Kelly, …
