The Highlands of Iceland cover most of the interior of Iceland.They are situated above 400�"500 metres and are mostly uninhabitable,because the water precipitating as rain or snow infiltrates so quicklyinto the ground that it is unavailable for plant growth, which resultslargely in a desertlava and volcanic ashes. A few oasis-like areas, such as Herðubreiðarlindir near Askja, are found only in proximity to rivers.
