Abstract [en]

The area of Lycksabäcken northwest of Lycksele is a national interest of natural conservation

because of its geological values with many unique landforms. Many of these landforms indicate

that the deglaciation process in the area was very complex. However, the deglaciation process in

the area has not previously been fully understood. The aim is to add to the knowledge of the

events that took place during the last deglaciation. To do this, the glaciofluvial landforms in the

area were mapped by studying aerial photographs with a Wild Aviopreter and a five-day field

inventory of key areas for the interpretation. These landforms were then transferred to a map in

ArcGIS in which scenarios of the deglaciation were constructed. The inversion from landform

pattern to a scenario of the deglaciation was based on seven general assumptions and the

attempt to create the least complex explanation of the origin of these landforms. The results

show that the valley of Umeälven must have been blocked at least three times during the

deglaciation in the area, which lead to a redirection of the meltwater flow into the area of

Lycksabäcken. There, dead ice played a major role in the formation of the glaciofluvial landforms

by damming lakes which enabled delta formation, the formation of many meltwater channels

and a large sandur. During the field inventory a large amount of preglacially weathered rock

surfaces was found in the area which would be interesting to investigate further.
