Maybe so, but we can still see the results in areas with vertical cliffs. We can see water seeping right out of a cliff face.
I thought everyone might like these pictures of a cliff side community.
The first picture shows the entire cliff. Water is seeping out of the limestone in the bottom center of the picture just above a harder less permeable layer.
The second picture shows the community of plants that resides on this West facing cliff seep.
The third picture is a closeup of Primula mistassinica from this cliff side seep community. If you look closely you will be able to find this plant in the center of the second photo.
I was never sure about the identification of the other vascular plant species shown in the photo. One appears to be a Parnassius.
