[2] The Nendelgin rises at the western edge of the central area of the Chersky System.

The range stretches in a roughly southeast to northwest direction for about 170 kilometers (110 mi), rising above the right bank of the Adycha river.

The 134 kilometers (83 mi) long Delakag (Dzholakag or Dyolukaakh), a right tributary of the Adycha, cuts across the mountain chain roughly in the central part, dividing it into two parts.

The highest point of the range is 1,777 metres (5,830 ft) high and is located in the southern part.

The higher Borong Range, another subrange of the Chersky Mountains, rises to the east.
