History: Central Park In The Early 1900s, Manhattan, New York City, United States

Cameron's Line is a fault zone that traverses Central Park on an east-west axis.
Various glaciers have covered the area of Central Park in the past, with the most recent being the Wisconsin glacier which receded about 12,000 years ago. Evidence of past glaciers are visible throughout the park in the form of glacial erratics (large boulders dropped by the receding glacier) and north-south glacial striations visible on stone outcroppings.
