Geology
The bedrock in Rondane comes from a shallow sea floor, created 500 to 600 million years ago. From this, changes in the Earth's crust created a mountain area of metamorphic rock and quartz. There are no fossils found in Rondane today and so it is thought the sea where the rock came from contained no animal life.
The present landscape was mostly formed by the last ice age, nine to ten thousand years ago. At that time large quantities of ice were formed, and it is believed that the ice melted gradually in shifting cycles of melting and ice accumulation. The ice melting must have been rapid when it happened, digging deep river valleys.
Rondane contains a few small canyons which were created by the rapid ice melting, most prominently Jutulhogget and Vesle-Ula.
