If you go to west from the old heliport in to Sisimiut and instead follow the grawel road that winds into valley road at bottom of Ulkebugt, it is the the best introduction to the area’s geology. After crossing the small river that with its fresh water, as many of the locals get water of for tea, coffee or for fill their waterbottle, flows out to Ulkebugt, the road rises slightly and run around a mountain massive. The rock, which are widespread in Sisimiut area, is described as Charnockit, a granite varied with high content of silica, perthit and hypersthene stones.
Near the end of the road, further into the valley above the lake, you find yourself on a plateau where digging sand and gravel for use in the town. The gravel plateau is over 20 meters above normal high tide. Here are quantities of shells of mussels, barnacles and other marine organisms. The majority of the species is the same as the living in sea stick. The plateau is called a marine terrace formed in the coastal zone for a time after the ice sheet had melted away from the valley, but within the country, which had been pushed down by the ice pressure, yet had risen.
The little trip into the nature gives a sense of the span of the geological work in the area arouns Sisimiut. In the following only discusses a problem area within the quaternary, and here only in the youngest part, namely for the past 4000 years, the beach line location has changed, while people have left their mark in Sisimiut region.
