Here are some pictures of the long exposed roots of a live oak
that I came
across several years ago while on a bike ride (hence the folks in
and helmets). This is not the normal architecture for oak roots.
the tree seeded on top of a spoil bank or levee along the adjacent
the roots grew down the side of the bank. Over the years the soil
washed out leaving a several foot void underneath it with the roots
supporting a fairly large tree.
The first picture shows the void with a fellow cyclist up under it
The second picture is a side view and about dead center under the
can see daylight through the roots.
The third picture shows the backside of the tree, still elevated a
feet above the dirt.
