Glacial Erratic

Approximately 30 miles from the hustle and bustle of New York City, the Preserve is an idyllic spot for strolling, jogging, horseback riding, cross country skiing, and snowshoeing.

One attraction at the Rockefeller State Park Preserve in North Tarrytown is a giant jagged chunk of rock at least 600 million years old. This mass of free-standing gneiss, almost 20 feet high and 65 feet in circumference, is probably the largest ''glacial erratic'' to be found anywhere in the county.

Getting There

The site of the giant boulder is less than a 10-minute walk from the preserve's main-entrance parking area off eastbound Route 117, down a lovely woodland path named ''Nature's Way.''

"probably largest in the country." ....... Probably not ?

There's also an outcropping on eastern end of property near a parkway.......I've always imagined "raven rock" mentioned in passing by Irving in "sleepy hollow" was located in the area...... May 27, 2018
