Consider that as we walk through a forest, or just stroll upon the land, we are continually intersecting and meshing our personal fields with those of the more-than-human world within which we live. Just as these fields impact us, so ours impact the land around us. It is sad that in this society the chief human impact is destructive even as we try and get into wild nature to help attain some inner peace and greater perspective on our lives. But it needn't be so, and while this insight is particularly in tune with a Pagan sensibility, it is hardly confined to one.
If we are immersed in changing gestalts of energy fields, some small and temporary, some generated by plate tectonics and other titanic sources, and most in between, the idea of gateways gains credence. This is particularly the case if those fields spill over into other dimensions, as I believe they do.
When a place, big or small, fleeting or long-lived, attracts your attention as particularly important for you, honor it. In doing so you add your own energy to that spot in a respectful way. This strengthens your own connections to the powers of the earth.
Perhaps walking in this thoughtful and aware way is the insight about "beauty" expressed so wonderfully in the Navajo Blessing Way chant:
In beauty (hózh'q) I walk
With beauty before me I walk
With beauty behind me I walk
With beauty above me I walk
With beauty around me I walk
It has become beauty again
It has become beauty again
It has become beauty again
It has become beauty again
