About this map

Tonzona River dominates this interior landscape as it winds across a wide, low-lying basin in the Yukon-Koyukuk region. The water system is further defined by the N Fork Jones Cr, which drains toward the main river channel from the south. This terrain transition is anchored by the Birch Hills, a cluster of elevated features in the southeast corner that provides a stark contrast to the surrounding river flats and wetlands. Grounded in a 2009 SPOT imagery base, the map reveals a largely undeveloped wilderness where natural hydrology and subtle topographic changes dictate the character of the land, lacking any established road networks or permanent settlements.
