The name is Aymara: ch'iyara means black and qiri means scale, so Ch'iyar Qirini is "the one with a black scale". The mountain is also spelled Charquerini and Chiar Kherini. It lies in La Paz Municipality, Murillo Province, near the El Alto Municipality border.

Ch'iyar Qirini has no marked trail or facility; the sources record only its position north-east of Chacaltaya and north of the two Qillwani Lakes, in La Paz Municipality near the El Alto border. Approach from the Chacaltaya side, where the access road ends, and treat the final slopes as unmarked high-altitude terrain at 5,363 m.

Two lakes called Qillwani lie north of the peak and provide visual landmarks in this high mountain landscape. These water bodies demonstrate how the high Andes are shaped by glacial melt and alpine hydrology.
