Deep Notch

Deep Notch, sometimes West Kill Notch, or Echo Notch, is a mountain pass in Lexington, New York, United States. It divides two Catskill peaks, both subpeaks of high peaks of the range. The narrow groove between the steep, high slopes on either side is traversed by state highway NY 42 and the Shandaken Tunnel, part of the New York City water supply system. It has been called "striking" and "a marvel of grandeur and beauty". The rocky slopes have required extra fencing at the base to prevent slides from blocking the road, the only paved road from northwestern Ulster County to neighboring towns in Greene County. Their steepness has also made them attractive to ice climbers, a recreational opportunity not widely available elsewhere in the Catskills.
