National Geographic’s Maps Division and Center for Sustainable Destinations teamed up to produce the first NG-developed Online Geotourism MapGuide to support sustainable tourism across the Greater Yellowstone region of Wyoming, Montana, and Idaho.

The site, http://www.yellowstonegeotourism.org/, which launched on March 31st, is open to anyone to discover and share information about unique features, tours, and businesses that best represent and sustain the natural and cultural character of the region. Visitors can also request a free print MapGuide.

Geotourism is the kind of travel that sustains or enhances the geographical character of a place — its environment, culture, aesthetics, heritage, and the well-being of its residents. Online Geotourism MapGuides are web versions of the print maps that National Geographic has developed for a number of regions around the world, including Crown of the Continent, Baja California, and Vermont’s Northeast Kingdom to name a few.

In addition to producing print and/or web maps, these projects bring together diverse representatives from the local communities to collectively define what makes their region special and how best to communicate it to the rest of the world. NG Maps is excited to participate in these projects that help travelers and local communities discover and preserve special places around the world. Anyone interested in developing a Geotourism MapGuide for their region, or simply becoming a “Geotraveler” should visit http://www.nationalgeographic.com/travel/sustainable/.

This case study aims to identify the cubic capacity and geometry of the geological body of silt–organic sediments in the environment of a former gravel pit situated in a drainless depression of the alluvium of the Čierna voda River. It is located in the well-known geotourism locality of Slnečné Jazera in Senec, in the SW of Slovakia. To identify the body, electrical resistivity tomography was combined with the use of sonar. The research shows that this approach is appropriate for a number of activities that are subjects of engineering-geological investigations. The cubic capacity and geometry of specific aqueous engineering-geological environments must be determined in connection with the need for the management, control, quantification and extraction of selected sedimentary bodies. In addition, the management of sustainable development of reservoirs, sedimentation basins, industrial ponds, settling pits and natural pools for recreation (the subject of the case study) is important to control the limit amounts of sediments in such environments. The results of this study may be applied in analogous engineering-geological conditions. The drainless depression Slnečné Jazera contained a body of silt–organic sediments amounting to 23 000 m³ (41 Olympic-size pools of 25 m x 12.5 m x 1.8 m). The maximum thickness of the bottom sediments was about 6.3 m on the alluvium with an articulated morphology owing to the submerged digging of gravel. The proposed approach improved the control of extraction of the sedimentary body and optimized the engineering-geological conditions in this geotourism locality.
