Öxnadalur. The trees are part of Jónasarlundur (Jónas's Grove), a roadside memorial park dedicated in 1996 and located on the land of the farm Steinsstaðir, where Jónas grew up. Öxnadalur River (Öxnadalsá) can be glimpsed on the right. For the identity of the various peaks on the horizon, see the caption for the illustration of Steinsstaðir in the biographical sketch.
