Routes in Northeastern Adirondacks?

I’m looking for some routes in eastern Essex County, NY from or near the Essex/Willsboro/Keeseville areas on Lake Champlain.   Seems like the dirt I used to ride regularly on my road bike has been or is in the process of being paved over.  I’ve been exploring some seasonal roads and Jeep trails that aren’t on gravelmap.com or RidewithGPS.com (or on any maps for that matter) with mixed results.  I’d like to find some routes with substantial amounts of gravel and dirt.  Starting or finishing from the Ausable Brewing Company in Keeseville or maybe the Dogwood Bakery in Wadhams could be a plus!   Anyone from the Champlain Valley or the ‘Daks here? 

So full disclosure, the below link is a bikepacking route, so it may contain some pavement or singletrack.  But, there are most definitely gravel roads included.  I am not intimately aware of any specific gravel roads or networks in that region, but I do know they exist.  So you may run into some good ones if you have a starting point.
