Rockslides in East Kingston

Two recent rockslides on Main Street in East Kingston are being monitored by Ulster town officials, Callanan Industries and state authorities. The first rockslide, which occurred on Thursday, July 25 with another minor slide on Friday, Aug. 9, happened on Callanan’s East Kingston quarry site.

According to town officials, the pair of rockslides appear to have been caused by the collapse of an historic cement mine opening created in the late 1800s, and were not related to blasting, which was not happening when the slides occurred. Callanan suspended all blasting on Aug. 12 to ensure the safety and stability of the slopes overlooking Main Street.

One day after the smaller slide, concrete barriers were placed on the west side of Main Street as a precautionary measure to prevent rocks from falling onto or crossing the road while studies are being done by geotechnical consultants hired by Callanan. The analysis will cover potential future operations in the quarry. The East Kingston quarry is one of several across the state being mined by Albany-based Callanan Industries, which trades in paving materials, concrete and other aggregates.


“Callahan is working diligently to make sure that there is no enhanced risk to the residents of the Town of Ulster in East Kingston,” Town Supervisor James Quigley III said Tuesday, Aug. 13.
