Few people live there. But there are some farms in few of the deep wallies there. But not many to my knowledge. This area also once hosted a large glacier. But there are few remains left of it today. This area is mixed in rock. But this rock also holds a different age and origin far as I know. There are theories that this might be a old continent crust that make up Tr\u00f6llaskagi.<\/p>\n<p><strong>The extinct volcano<\/strong><\/p>\n<p>There are more interesting things around Sau\u00f0\u00e1rkr\u00f3kur then just Tr\u00f6llaskagi. This caldera is one of the visible features from Sau\u00f0\u00e1rkr\u00f3kur. The current conclusion about this caldera it is extinct. While I personally don&#8217;t agree with that and believe that it might still be active given it shape. I have no way to prove it, unless it starts to erupt all of a sudden. This is a stratovolcano with a small caldera. This volcano formation is small compared to many other Icelandic volcanoes. Both active and extinct. <\/p>\n<p><a href=\"http:\/\/icelandgeology.net\/wp-content\/uploads\/2010\/11\/PB110005.jpg\"><img loading=\"lazy\" decoding=\"async\" src=\"http:\/\/icelandgeology.net\/wp-content\/uploads\/2010\/11\/PB110005-300x225.jpg\" alt=\"\" title=\"\" width=\"300\" height=\"225\" class=\"aligncenter size-medium wp-image-218\" srcset=\"https:\/\/icelandgeology.net\/wp-content\/uploads\/2010\/11\/PB110005-300x225.jpg 300w, https:\/\/icelandgeology.net\/wp-content\/uploads\/2010\/11\/PB110005-1024x768.jpg 1024w, https:\/\/icelandgeology.net\/wp-content\/uploads\/2010\/11\/PB110005.jpg 2048w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/><\/a><\/p>\n<p>A zoom in of the extinct volcano caldera.
