Great Falls of the Potomac - Part 1

The Maryland side of the Great Falls of the Potomac are part of the C&O Canal National Historic Park. It was our Labor Day outing this year. Quite a lot of people had the same idea. The parking lot was already half full of cars and there were joggers and walkers - people on their own, couples, groups, families. Starting out the path between the canal and river shows the slower, shallow edge of the river through rocks.

I noticed a tree growing on what looked like solid rock.

The roots cling to each nook and cranny in the rock. Even in the zoomed view below it does not appear that there is much soil.

And then we get to the end of the boardwalk that lifts us over the side channel and over the last rocky ridge to the make falls. The rocks here are scoured bare by water.

To give you a sense of scale - the picture below shows the platform for visitors to view the falls from the Virginia side of the river.

Even with the scouring of the water, there is an algae film visible on some rocks.

When I looked more carefully at one of them I noticed a large pothole had formed. The water level on Labor Day was not high enough to scour it….but the water must get high frequently enough to form it. I’ll look for it every time I go from now on!
