The people of Tupper Lake, the ADK Park Conservancy, and private investors have been butting heads over the issue of a resort-type improvement to Big Tupper for quite some time.
Big Tupper used to be a nice locals resort, but given its proximity to Whiteface, its relatively low snowfall totals, and its lack of state funding it was not able to stay open. The infrastructure at the mountain is outdated, there are now detachable chairs or new equipment. The top of the mountain was rarely open.
With that said though, it was a nice place to ski. No crowds, mostly locals and none of the hype that is whiteface/Lake Placid.
PBS just did a really nice documentary on the ADKs and there is a short section about Tupper Lake and the proposal to expand and reopen Big Tupper. The concerns range from environmental to economic and local zoning will have a lot to do with the decision. Its important to note that the Adirondacks are not exclusively a forest preserve, there are many communities and high impact recreation activities that take place within the Adirondacks. The Adirondacks have always been about the conservation and use of resources to be able to thrive in a relatively harsh environment for survival of industry and community. That is way the expansion of Big Tupper seems to be a no-brainer, it fits with the traditonal ADK mentality of landuse , but the prospect of selling condo and investing in a ski area so close to Whiteface is a dangerous one. Also, given Big Tupper's location you can't expect people from Albany, Montreal, or any other large population to go there over Whiteface.
I hope this helps, and check out the PBS special on the ADKs it will provide you quite a bit of insight to the situation at Big Tupper.
