Abstract
Megaclasts are sedimentary particles larger than boulders. Their huge size and scattered occurrence make them objects
that deserve geological heritage, requiring conservation. Investigation of megaclasts for the purpose faces difficulties
because of the distinction between boulders and megaclasts. Local study of Quaternary large stones in Mountainous
Adygeja (W Caucasus, SW Russia) suggests ~ 2 m as a suitable size criterion, although only locally. Shape, occurrence,
and origin of megaclasts require additional attention.
Geoconservation may result in anthropogenic disturbances of the natural landscape through removal of vegetation,
access constructions, and restoration. The geotourism potential of megaclasts is partly determined by their huge size
and their rare and scattered occurrence. Aesthetic qualities, local legends, and co-occurrence with prehistoric megalithic
constructions increase this potential. The Maiden’s Stone in Mountainous Adygeja, which is ~ 35 m long, has been a tourist
attraction already for decades. It is an impressive example of geoconconservation and geotourism connected with
megaclasts. Generally, megaclasts increase the value (including the scientific importance) of the geological heritage of
Mountainous Adygeja, where a geopark might be established.
