The Kiyera Lake map area straddles the northwestern extent of the Nisling Range. Broad treeless uplands dominate the landscape with summits reaching above 1800 m above sea level. Upland surfaces are characterized by weathered bedrock colluvium, tors and sporadically distributed till deposits from former alpine glaciers in cirques. Upland surficial materials are affected by active periglacial processes such as cryoturbation, nivation and solifluction.
