Geological Aspects
The lake sediment units found in the Huta Tinggi area consist of sediments in a calm water environment (lacustrine), consisting of alternating pyroclastic material ranging from gravel-gravel to silt-sand. There is a normal-stepped fault structure, thought to be related to the local tectonic dynamics that occurred after the deposition of the above material. In the middle of the caldera which has become a lake with a water level of + 900 m above sea level, there is Samosir Island, oval in shape, with The highest place reaches 1600 m above sea level. The presence of several stagnant lakes or reservoirs (sag-ponds) makes this area unique, namely ‘an island (Samosir) above an island (Sumatra) and a lake (Aek Natonang etc.) above a lake (Toba)’. The formation of landscape lineaments and the presence of several rain-fed lakes on Samosir Island with certain directional orientations, indicate the similarity of the lineament patterns with the Great Sumatran Fault system. The formation of rain-fed lakes on Samosir Island (Aek Natonang, Sidihoni etc.) indicates that the land surface in these places is relatively impermeable, this is one of the characteristics of lake sediments which are silty (water-impermeable).
Biological Aspects
The Geosite area is occupied by residential communities with economic activities such as cultivating rice, corn, coffee, sweet potatoes and raising buffalo which are used as activities for tourists visiting the Geosite.
Cultural Aspects
Huta Tinggi Tourism Village is one of the villages in Pangururan District, Samosir Regency and was designated as one of the Tourism Villages through Samosir Regent Decree Number 372 of 2019 concerning Determination of Tourism Villages in Samosir Regency. This village’s superior product is a tourism package based on local wisdom which has been sold and marketed to domestic and foreign tourists. The program that is expected is the HR Capacity Building Program, namely in the form of Foreign Language Training activities which are equipped with TV facilities, Infocus, sound system and bookcases. Meanwhile, the Program for Providing Facilities and Infrastructure that is expected is the Rejuvenation Program for Lapo Tuak (Taak Tuak) as a Tourism Lapo (Batak Wine), Construction of a Photo Spot Area, Procurement of traditional Musical Instruments and keyboards, Uniforms and accessories for Art Studio Performances, construction of information panels as well as the construction of a tourist village gate at the entrance to Huta Tinggi Village. It is hoped that this HR Capacity Building and Facilities and Infrastructure Provision Program will provide extraordinary benefits and can reach the entire Huta Tinggi village community. All village communities are involved in this tour package, starting from children as cultural arts actors, some adults as culinary and food processing project actors, village tour guides as companions for tourist activities as well as educational and story telling sources, agricultural land owners as well as farmers and breeders as providers and companions of tourist activities/attractions and owners of lapo (tuak/Batak Wine shops) as providers of entertainment and places
