Grímsnes is a relatively small volcanic system located SE of Thingvallavatn lake east of an en echelon group of volcanic fields extending across the Reykjanes Peninsula.  The Grímsnes volcanic field is seen here in an aerial view from the SW.  Grímsnes lava flows cover 54 sq km and were erupted from a group of 11 fissures that produced a series of NE-SW-trending crater rows, such as seen at the lower right.  The eruptions of the Grímsnes lavas were restricted to a relatively short interval between about 6500 and 5500 years ago.      Photo by Oddur Sigurdsson, 1991 (Icelandic National Energy Authority).
