The Threngslaborgir fissure cutting obliquely down the center of the photo extends to the south from Krafla caldera.  The younger Laxarhraun lava flow, which originated from the 8.5-km-long Threngslaborgir-Ludentsborgir crater row about 1900 years ago, covered much of the lake Myvatn area and flowed down the Laxardalur canyon to the northern coast.  Numerous pseudocraters formed when the 2.5 cu km lava flow entered the lake.   Photo by Richie Williams, 1981 (U.S. Geological Survey).
