It's not about sunflowers...
This photo is not about sunflowers. This is about the highpoint of Jász-Nagykun-Szolnok County of Hungary - called Hármashatár. This county is on a flatland, so the highpoint has only a 136 m altitude. Its relative elevation is 20 meter to the neighbouring "valley".
The name Hármashatár means Tripoint.
The hill is not much important. The county is more important: in 1876 it was merged from lands originating from the 13th century.
