The Opalescent River drains the col between Mount Marcy and Mount Skylight, carving through the remote heart of the High Peaks — arguably the most storied backcountry watershed in the Adirondacks. It feeds Lake Tear of the Clouds (the highest source of the Hudson River) at its upper reaches and runs north through Feldspar Brook territory before joining the outlets near Flowed Lands. Access requires a full-day commitment: this is backpacker and through-hiker water, not a roadside stop. The river's name comes from the milky, opalescent color of glacial silt in the current after rain — a fleeting effect, but unmistakable when you catch it.
