  abstract = {{A}erial photographs of the {C}otopaxi {V}olcano ice cap dating from 1956 to 1997 were used to quantify the evolution of the surface area. {R}esults were obtained using precise stereoscopic methods that give the most accurate information. {I}n addition four specific glacier tongues were investigated in detail to measure the ice mass lost between 1976 and 1997. {S}urprisingly, the bedrock morphology is shown to be very irregular and this explains a large extent of the variability found in the ice losses. {T}he results show that glaciers stagnated from 1956 to 1976 and lost about 30% of their surface area between 1976 and 1997. {S}lope exposure did not seem to have any significant effect since all the glaciers of the volcano retreated in the same proportion. {I}n accordance with specific measurements performed on the nearby {A}ntizana 15 {G}lacier, it is suggested that the strong recession observed after 1976 was associated with increasing melting conditions which have occurred repeatedly during the intense/long-duration warm {ENSO} phases.},
