Sitting on 400 acres, the Tamarack lodge was built inthe early 1900s as a simple boarding house and was expanded in 1927. At its peak it would have 300 rooms and the resort had all the activities one would expect from a retreat in the Borscht Belt of Ulster County, NY. The location primarily catered to jewish familes and provided popular entertainment of the day, which in the 60s meant Cream, the Who and Janis Joplin.
There was a massive fire in 1995 which effectively shuttered the resort.It remained functionmal till 2000 when the health dept closed them down. the property sat unused for a decade until another fire broke out destroying 30 buildings in 2012.
Now there is very little left. There are only 3 primary buildings left along with some sort of storage building and a half dozen bungalows at the back of the property. the main building floors are extremely unstable and the rar building has had a partial collapse of the roof.
You can see pictures of it before the fire at this site.

The bungalows are demolished now and the rest of the site is fenced off with asbestos warnings, heavy machinery, and 4 industrial sized dumpsters. The main building’s windows are boarded up indicating it’s to be demolished very soon. They’ve removed much of the debris from the fire and you can actually see the old pool again since all the debris on top if it is gone.
