You will get the best introduction to the area’s geology if you go west from the old heliport into Sisimiut and follow the gravel road, that can be found at the bottom of the Ulkebugt. After crossing the small river, that flows out to the Ulkebugt, which provides many of the locals with water for tea and coffee or to fill their waterbottles when they are hiking, the road rises slightly and runs around a massive mountain. The rocktype, which is widespread in the area around Sisimiut, is described as Charnockit, a granite with high content of silica, perthit and hypersthene stones.

Near the end of the road, further into the valley, you find yourself on a plateau above the lake, where you can dig for sand and gravel for use in the town. The gravel plateau is over 20 meters above normal high tide. Here are huge amounts of seashells, barnacles and other marine organisms. The majority of the species are the same as the ones living in sea. The plateau is called a marine terrace, formed in the coastal zone some time after the ice sheet melted away from the valley, but the country, which had been pushed down by the ice pressure, has risen again.

The little trip into the nature gives a sense of the excitement of the geological work in the area around Sisimiut. Only an area within the quaternary is a problem area, because the beach line location has changed for the last 4000 years.
