What are these? - NOT amateur radio
We saw these at Hare Park, Chippenham, near Cambridge. They are wooden, not stone, objects. They are about 3m from the tree. If they are part of the tree roots, they are odd.
"Visible throughout the year are the tree roots that buckle up above the surface of the lake into knobbly 'knees', known as pneumatophores. They are characteristic of swamp cypress trees growing in waterlogged soils or open water."
