name from the Spanish word for cows – local livestock commonly frequent the entranceway and their dung may be thickly deposited underfoot. This narrow passage is about 12 m long (with a surface area of 7 m2) and it rises upwards on entering the cave interior, before connecting with Azokh IV chamber inside.
Azokh I: The Stalagmite Gallery
With a total surface area of 843.5 m2 the Stalagmite Gallery is the largest inner chamber of the cave system at Azokh (Figs. 3.13 and 3.14; see also Fig. 3.8 for general location). The name was originally coined by the previous excavation

A large conspicuous stalagmite, which gives the gallery its name, is located at the extreme right of this image (along the SE wall of the chamber); b The termination of the NW branch of this gallery, leading into the second gallery (Azokh II). Note the thick bands of chert, which are laterally persistent for several meters, forming cornices; c The stalagmite; d The largest known panel of speleothems in the cave system, protected from corrosion by overlying chert cornices. This panel includes flags and a c. 2 m high column

team (Huseinov 1985) in reference to the large conspicuous stalagmite found along the SE wall of the chamber (Fig. 3.13c), a short distance from the narrow connecting passage to Azokh 1.
The Azokh I chamber divides into two branches (Fig. 3.8), as follows:

distinctive inflection in the cave ceiling and the ground slopes slightly distally. This lower part of the gallery (overlain by the low ceiling) has a surface area of 38 m2. The ground surface of the crawling pass is composed of loose sediment, most of which is completely undisturbed.
•Branch 2 opens towards the left hand side (NW) as one enters from Azokh 1 passage and continues for some 47 m in a northwesterly direction (i.e. orthogonal to the first branch), before connecting with the next inner

chamber (Azokh II). There is a steady slope on the floor of this gallery, ascending 8 m elevation in less than 23 m. The NW end of this chamber ends with a large chert cornice on the northern wall (Fig. 3.13b). A second (lower-level) access route to Azokh II is present below this feature (Figs. 3.13b and 3.14d).
The limestone walls of the Stalagmite Gallery are mostly light in color, with broad and shallow concave surface depressions. In the northern wall of Branch 2 a large band of overhanging chert is located at about 2.5 m above ground level. This is a common place for bats to congregate and, as a result, a half meter thick mound of guano has developed beneath it. This block of chert also protects parts of several speleothems covering the wall from corrosion. This panel of speleothems is about 3 m long and 2.5 m high, and stalactites, flags and a 2 m high column are present (Figs. 3.13d and 3.14a).
Very close to the walking passage connecting through to Azokh II, a large block of chert hangs from the ceiling via a
narrow pedicle of limestone (Fig. 3.14e). This feature provides evidence for the intense corrosion of the cave walls during the late evolution of the karst system. A short distance beyond this (Fig. 3.14c), is another large block of chert hanging from the ceiling at waist level (Fig. 3.14b). It is less obvious, due in part to its close proximity to a large underlying debris cone of sediment (from a collapsed gallery).
The ground sediment in the Azokh I chamber is a sandy-clay, with a thin veneer of more clay-rich material. During the summer months, when excavation and survey work is in progress, this sediment is usually found to be slightly damp. The access route to Azokh II was dry during a visit made by PDA in November 2007. The ceiling in this part of the cave used to have a few thin straw stalactites, which were fairly recent in age and active during the summer. The debris of a large collapsed chamber is located nearby (Fig. 3.8) and possibly acts as a water reservoir for this feature. Several meter-scale depressions occur on the

The gallery is named after this feature
