Answer:
50 lakes
Step-by-step explanation:
About 50 glacial lakes and ponds appear on the 1:50 000-scale topographic maps of Costa Rica, all above 3 440 m in elevation in a 15 km2 area surrounding Cerro ChirripĆ³. The lakes occupy glacial depressions formed in bedrock, in till deposits, or a combination of the two. More than half generally hold water year-round.
