Slovak authors Robert K. Lesniakiewicz and Miloš Jesenský (pseudonym Manfred Jensen) published their own discoveries in Poland (in Tajemnica Księżycowej Jaskini (2006) and Powrót do Księżycowej Jaskini (2010)) and later in the United States (The Mooncave Mystery (2020)). They believe the Moonshaft to be a section of an underground network of tunnels related to the mysterious glass tunnels in Babia Góra in Poland. Czech author Martin Lavay performed his own excessive research and discovered that fights similar to those described in Horak's diary occurred in Low Tatras close to villages Telgárt and Vernár. Together with author Jaroslav Mareš and researcher Erik Vojtek, they found an extraordinary rock formation they called rock eye near mountain Kráľova hoľa. However, due to the national park rules, they were not allowed to go any near the object. Lavay published the results of his research in his book Měsíční jeskyně (2019) and on Youtube channel záhady.info. Jaroslav Mareš shot a segment for his project badatele.net. In 2019 Slovak web portal Cez Okno received an information, that one of their followers identified a place in a small mountain range Baruchňa where vegetation grew in a shape of a crest. He believed the Mooshaft to be a slickenside - two enormous blocks of sandstone moved in opposite directions which resulted in smoothing and darkening of their surfaces. Natural geological processes caused the gap between the two blocks to grow bigger which created the unusual cavity. However, no proof that the place in Baruchňa is a Moonshaft was presented. The same year, explorer Erik Batysta visited a cave in Belianské Tatry. He found a fireplace, letters written on one of its walls and a pile of stones that looked like a grave. The cave had an opening in the rear wall but seemed to be too unstable to be explored safely. Part of the cave collapsed later that year.
