The western face of Esja, which overlooks Reykjavík. The cliff is partly the result of glacial erosion and partly of marine erosion at the time of the higher marine limit following the last glaciation about 11,000 years ago. This was followed by rapid uplift to the present position. The erosion has exposed lava and altered móberg strata. Along the bottom of the cliff are talus screes, while the backward dipping lavas of a slumped block can be seen to the left.
