Glacial and periglacial geomorphology of central Troms and Finnmark county, Arctic Norway
Here we present a glacial and periglacial geomorphological map of a ∼6800 km 2 region of central Troms and Finnmark county, Arctic Norway. The map is presented at a 1:115,000 scale with the aim of characterising the spatial distribution of glacial and periglacial landforms and facilitating the recon...

The map records several noteworthy large moraine assemblages within individual valleys, forming inset sequences from pre-Younger Dryas limits up to the 2018/19 ice margins and represents a valuable dataset for reconstructing Holocene glacial and periglacial activity.
