Vízesési Cavity

The Vízesési cavity is one of the cavities located in the Danube–Ipoly National Park, in the Holdvilág trench at Pomáz.

Description

At the periodic waterfall of the Holdvilág trench, in the line of the waterfall, on the upper part of the rock wall, about three metres below the edge. Its entrance is clearly visible from below, but the iron ladder that facilitates climbing the waterfall rock wall also allows a partial view into the cavity.

Entering the cavity is possible only with a rope and when exploring it, it is advisable to approach the entrance by descending.

Its entrance, 90 centimetres wide and 170 centimetres high, faces roughly west. The entrance is followed by a single 3.5‑metre chamber that slopes sharply outward. Nevertheless, its height gradually increases because the ceiling rises even more strongly than the floor level. The highest part is at the inner third of the chamber and is two metres high. The side walls consist of a standing‑in‑column, larger slab‑containing andesite block, while the floor and ceiling are formed by a loose assemblage of smaller and larger stone blocks.

The cavity also appears in the literature under the name Vizesési‑cave (Eszterhás 1993).

Formation

Its formation probably occurred as follows: debris that had previously settled in the wider part of the rock stair forming the waterfall, indicated today by the cavity’s side walls, was later shaped into a cavity by periodic erosion and rock collapse. Its ceiling is one to one and a half metres below the upper streambed of the periodic waterfall; the position of the rock blocks that form it is very unstable, so it is expected that it will collapse and be destroyed in the near future. If no personal injury occurs in the meantime, that will be due only to luck.

Research History

In 1991 György Ézsiás described it for the first time. In the manuscript titled *Magyarország nemkarsztos barlangjainak lajstroma* written by István Eszterhás and produced in 1993, it is stated that the Vizesési cavity was formed in the andesite breccia of the Visegrád Mountains, in the 4900‑meter cave‑catastrophe area, located in Pomáz. The cave is 2.5 m long and 1 m high. The compilation lists the 520 objects (478 caves and 42 artificial cavities) created in Hungary in non‑karst rock that became known by the end of 1993. In Hungary, 12 caves or artificially created, cave‑named cavities formed in andesite breccia. In the Visegrád Mountains, 33 caves formed in non‑karst rock.

In 1997 István Észterházy examined the cavity in detail. The manuscript titled “Bibliography of the Caves of the Hungarian Karst” dated 12 November 2001 lists the Vízesési cavity in its cave name index. The index lists three literary works that deal with the cavity. Items 364 and 366 do not mention it, while items 363 and 365 do. In the study published in the 2014 Yearbook of Karst Development it is stated that the Vízesési cavity located in Pomáz is one of the 101 caves of the Visegrád Mountains, measuring 3.5 m in length and 2 m in height.
