No site in New York's access file falls on the Opalescent River, so the way in is public ground and road crossings rather than a marked landing. 2 blocks of public land front the Opalescent River, and 14.3 of its 15.0 mapped miles run through them.
High Peaks Wilderness — state conservation department, 12.16 mi of this river, 275,300 acres in all
Vanderwhacker Mountain Wild Forest — state conservation department, 2.15 mi of this river, 99,350 acres in all
Ownership from PAD-US as the state publishes it. Where a block has its own page, the name
links to it. The river miles are how far this river's drawn axis runs inside each block, measured here;
the acreage is the whole unit's, most of which is nowhere near this water.
