Fig. 188 — Asymmetrical peaks in the Central Ranges between Antabamba and 

 Lambrama. The snow-filled hollows in the photograph face away from the sun — that 

 is. south — and have retained snow since the glacial epoch; while the northern slopes 

 are snow-free. There is no true glacial ice and the continued cirque recession is due 

 to nivation. 



Fig. 189 — Glacial topography north of the divide on the seventy-third meridian, 

 Maritime Cordillera. Looking downstream at an elevation of 16,500 feet (5,030 m.).
